Practice Forced Landing Briefing: The lesson that never was

November 24th, 2012 by PHC | Permalink

Normally if the phone rings before 9am on a weekend, it’s the aero club, often a good thing as it means there’s a last minute slot going 🙂    However, on this particular day the phone rang, but realising it was past 9am, this couldn’t be a cancellation.

It was still the aero club, but this time ringing to tell me I was late for my lesson.  ‘Lesson?, I never booked any lesson for this weekend, same time next week is what’s on my phone.’   Other than to suggest in over a year I’ve never missed one yet, we won’t go into who was right or wrong here, it doesn’t matter.

What made this particular call a bit strange was the background banter of whether or not I should just come in anyway:

“Come in….”
“What’s he doing?”
“Practice Forced Landings”
“Oh, well we don’t have the weather for that…”

Maybe I just wasn’t awake enough at the time, but after a debate of whether I could get down there quick enough to still grab the lesson, this banter was some what amusing  🙂

Bad weather seems to leave the instructors filing ‘important paperwork’ (possibly involving coffee and talking about the weather), so it doesn’t always mean it’s a total loss for a student.   I was invited to go down anyway and we’d go through the briefing for the lesson.   Good stuff (and the one thing in flying that is actually free! 🙂 ).

Practice Forced Landings

General idea is to get comfortable with the procedures involved should the engine stop or decide to burst into flames.

Without thrust, the aircraft will assume a landing configuration…….in as much as you’re going down whether you wanted to or not.

In the event such things occur, there’s a sequence of priorities and things to be getting on with in order to maximise the chances of the end result being a landing, rather than a crash.

Practice Forced Landing Briefing

Practice Forced Landing Briefing

  1. Set Best Glide Range Airspeed :  70 knots in a Cessna 172 – Anything faster or slower and your glide range will be reduced, though worth noting that best glide range is not the speed to set if you want best glide endurance……..but unless we’re trying to avoid ditching in the sea for the maximum amount of time possible, range is what we want.
  2. Select a Field : It might be a bunch of houses ahead of us, but perhaps there’s a field behind or on the far side of us, you never know your luck maybe even an airfield 🙂     Preferably into wind as this will reduce our ground speed, start planning – can we reach it etc.   When selecting a field, it’s all about the S’s:
    1. Size
    2. Shape
    3. Surface
    4. Slope
    5. Surroundings
  3. Restart Checks :  Assuming this is an engine failure, now we have given ourselves maximum range and know where we’re going to try and put the plane if all else fails, time to see if we can’t get the engine going again.
    1. Mixture:  Is it rich?   Exercise it and reset to rich
    2. Throttle:  Is it open?  Exercise it and set to about half power.
    3. Fuel Shut Off:   Should be ON   (fully pushed in)
    4. Fuel Tanks:  Select Both
    5. Aux. Fuel Pump:  ON
    6. Magnetos:  Left, Right, back to Both
    7. Try Restarting the engine.
  4. Check the Plan:  If it hasn’t restarted, time to double check we can still make the intended field, that nothing new hasn’t now come up to make that original field unusable (e.g. now we can see there are power lines etc.), are we still at the right airspeed.
  5. Distress Call:   Time to wake up the world……7700 on the Transponder to indicate an emergency, radio call “Mayday, Mayday, Mayday <Call Sign> <Type of Emergency> <Location> <Number of Persons on board>”.    Unless by some miracle there is an airfield within glide range, in which case this radio call should be enough to promote you to number 1 in the landing order.   Other than deploying the emergency services, that’s about all Air Traffic can help you with – so unless the engine restarts and the crisis goes away, not much need in talking to them after this.
  6. Check the Plan:  Airspeed / Can we still make it / Is it still the field for us.???
  7. Shutdown Checks:   This plane is now officially no fun, but it’s potentially going to be less fun if you hit the ground with everything live, time to turn it all off (If the emergency was a fire, you’d have already forgotten about restarting it):
    1. Mixture :  Lean / Idle Cut Off
    2. Throttle Closed
    3. Fuel Shutoff:   OFF (Pulled out)
    4. Aux. Fuel Pump:  OFF
    5. Magnetos:  Off

At some point we want to turn the Avionics and Master Switches OFF, however, the Avionics drives the transponder, so we might want to avoid turning that off straight away.   The master switch drives everything, if we turn that off, we’ll lose the avionics, the flaps, the lights…….primarily we’re concerned we might still want those flaps and we won’t want to take them early, because once the height is lost there will be no getting it back.   As a result these will be the last two switches to go off.

Circuit / Approach

As per the sketch on the white board above, the aim is to be at 1000ft at a specific point, or “Low Key” point.   From here the final part of the approach can be flown:

  • Too Low : Fly more directly to the aiming point
  • Too High: Fly away from the aiming point, or ‘S’ turn.

The idea is to aim for a touch down point about half way into the field selected, as the height is lost and it is certain we could make that point, the aiming point is brought closer to around a third into the field.   Though speed needs to be considered, as the book of words says:  “Better to reach the far end at taxi speed……..then to undershoot into the near side hedge at flight speed.”

At around 500ft, staying legal, the practice will be called off and a verdict of whether we’d have made it or not given.  It’s probably ironic that aircraft have some of the toughest design & production certification requirements of any industry – but you won’t find any air bags or crumple zones here, they’re designed for high probability of safety in the air, not crashing into a fence.

Well that’s the general theory…..

Next lesson we’ll see how it turns out in practice 🙂

Extra 200 & The Weather

G-GLOC in climb

G-GLOC in climb

Not having much luck with this plane at the moment, from it’s engine not starting, to it having a flat tyre and then bad weather.

It doesn’t seem to like me much.

Having recently had a few days off work I thought I’d have another go at getting up in it, but it was still not to be, two days of terrible fog and a cloud base of 200ft at its worst, forget doing aerobatics 🙁

We’ll keep trying though, all good things…..

 

Lesson 35: Advanced Turns

November 19th, 2012 by PHC | Permalink

The first words ever posted on this blog were:  “It’s going to be about flying and nothing but flying…”   The opening lines of the ‘about page’ at the time, setting the scene for:   “Why document it all anyway?”  ……and also a subtle hint that, as you might have noticed, I don’t name instructors.   That was always intentional for two reasons:  I was conscious from the get go that it’s not fun to find your name randomly on web pages and secondly a lot of what gets written up is subjective afterthought with lots of scope for error.   Why bring it up now?

This lesson ended with that slightly awkward moment, I’ve seen other blogs go through:

So are you still writing that blog then?

Busted…….it was inevitable, I’ve mentioned the aircraft names in every post (they can’t sue me for libel) and recently I was conscious of using the airports name and photographs more and more, it was getting easier and easier to stumble upon and be able to connect the dots.

Still, if you come away with any impression other than the club and instructors there are all fantastic – you’re on the wrong blog.   Fingers crossed my bad lessons grumble more at myself then anyone else, to enjoy the highs you must experience the lows….

Back in good old Whiskey Kilo :  Low Fuel

G-SHWK

G-SHWK

With a general lack of AVGAS at the airport, this lesson would be done in G-SHWK, it’s only been a few weeks apart, but I miss flying it 🙂

After a short discussion on the lesson and a general summary of lesson background theory and objectives:

  • Steep Turns (45 Degrees)
  • Collision Avoidance
  • Stalling/Recovery during a Steep Turn
  • Demo of a Practice Forced Landing

Actually ‘collision avoidance’ was more of a rationale for the need to do a steep turn. Finding a reason to do one (other than because they’re fun) was something I actually faffed around trying to find…..avoiding hitting something, so obvious!  :-\

On with the plane checkout.

Upon turning the master switch on, the fuel gauges read “5 gallons Left, ~10 gallons Right.”   That’s as low as I’ve ever seen (except for when they didn’t respond at all) and at that moment I was pondering going back and checking we were still taking this plane…….bit of quick math (~15 gallons in the tank, ~10 gallons/hour fuel consumption:   1 hour lesson + 30 minutes reserve).   Doable, I’d crack on and see if it was all in vain later.

The dip stick confirmed the fuel gauges could be believed.

Cleared for Immediate Take Off

Another one of those bizarre moments upon lining up for departure (why I find it bizarre I’ve no idea, but it is…).   Having called ‘ready for departure’, air traffic replied asking if we could accept an immediate clearance – we could, upon rolling on to the runway the plane on final approach made its radio call and I realised I knew the pilot……..now if I didn’t get out of the way sharpish and forced a go around, I wasn’t going to hear the end of it.   Full power!!!

A tip from my instructor that if ATC ask if we can accept an immediate clearance, we can just start rolling and accept as we go, rather than confirm we could, then get offered, then accept and get going.   Arguably the latter is more procedurally correct (otherwise you’re moving, potentially on to the ‘Landing Area’, without actually having a clearance to do so).   The counter argument would be one of inference…..Debate amongst yourselves, I do as I’m told 🙂

Once in the climb, looking down and left I realised I could see the runway, we were getting pushed right by the wind.  An average attempt to compensate followed.

Commencing a 20 degree climbing turn to the right, it was just a matter of time before Air Traffic would ask us to switch frequencies.

More R/T errors and Brain Stalling

A lot of time has been spent pondering the mental stall from last lesson, so I was hoping to avoid it.  It’s sort of strange that in the last 10 months, it’s only in the last 2-3 lessons that I’ve had to switch frequencies.

The call to actually switch frequencies went ok, it went wrong when I called Approach and they called back the QNH (pressure setting for measuring altitude above sea level), that for no obvious reason threw me completely…….maybe they said QNH 1011 and I didn’t hear the QNH, maybe they didn’t say QNH, all I know is I just heard “1011” – for which I found myself thinking “what?  what’s that?”

I’ve got to get over this locking up issue, it’s at risk of becoming a bigger headache then my previous obsessive desire to fly on instruments.

Steep Turns

After a couple of steep turn demos, executed with zero change in altitude (a tough act to follow!), it was time for me to have a go.

First a 180, 45 degree banking turn to the right.

It went pretty well, from my memory of the dials it was completed with +90ft (apparently the limit is +/-150ft, so not bad for my first go).

Followed by the same thing to the left (to prove it wasn’t a fluke), it wasn’t quite as good but still within limits.

Collision Avoidance Turns

Essentially the same maneuver, but without any of the smoothness in entering the turn/applying power etc.   Just roll straight into it as if your life depended on it…….compared to the steep turns I’ve done in the Extra this was still a very civilised affair, but a bit more aggressive in motion then the first two.

Stalling in a Steep Turn

Before any stall there is a HASELL check (Height, Airframe, Engine, Location, Lookout).  Normally the lookout is a 360 degree turn at 30 degrees of bank, as we were up here to do steep turns, why not do a steep turn orbit.   The longer you’re in the turn the harder it is to keep everything in check, it wasn’t my best orbit, but it wasn’t too bad.

When asked what the first thing to do to recover was?  I answered “roll the wings level” …..Wrong.  In hindsight I have flash backs to being told this is what people tend to do automatically when in a wing drop stall, the correct action is to actually push the control column forward and get airspeed first.   Ahhh the stuff not yet engraved in my brain…..

After a quick demo and noting that it’s actually quite hard to stall in such a tight turn, it was time for me to have a go.

You learn faster from your mistakes so at least running through the “what are you going to do” meant it went smoothly on the practical (lets  all now forget the answers given in the theory shall we).

Demo of a Practice Forced Landing

Nothing quite makes you want to come back for more, like seeing what you’ll be doing/attempting next.

Time to see a practice forced landing, albeit one executed more calmly and with seemingly much more time then it would feel if I was attempting it.   Picking a brown field and gliding down, warming the engine every 1000ft, to around 700ft before finally calling it off.   It always amazes me how calm and almost relaxing it is to be in a plane with essentially no power gliding to the ground……strange (perhaps I have blind faith in the engine restarting).

My glide approaches in the past had a tendency to undershoot, so we’ll have to see how it goes.

Returning home

The fuel warning annunciator was flashing low fuel, the gauges were saying roughly zero in a turn 🙁    and about 5 gallons in straight and level……..time to run for home.

A bit of a practice run with my instructor for the radio calls, this might actually go half decent for once.

…..and the hand over back to the tower went fine, all well until they asked how we wanted to rejoin.   Good question.   I’ve only ever done overhead joins, they had to be awkward and give me options 🙂

Descending back into the circuit via a crosswind rejoin, dropping a touch low and then going a touch high (+/-100ft of circuit height), it was an average circuit.

Crosswind Landing

The turn on to final was late, resulting in an overshoot leaving us right of the approach.   This needed to be corrected for while flying into a crosswind.   Historically my crosswind landings have been bordering rubbish, only recently have they started to touchdown without an almighty thud.

I can actually remember flying the approach pondering what I was doing……..yes we were staying straight, but it was a half crabbed, half rolled approach to keep it that way and noting previous lessons afterthoughts of It goes wrong because I’m not reacting fast enough, this approach had a ton of input.

Just above the runway I mentally reminded myself to stop looking at the asphalt and look along the runway, applying a bit more back pressure we touched down almost as smooth as I’ve ever landed.   The technique for getting down might have been debatable, but the landing was one of my better ones……and if you want to walk away from a lesson happy, it’s all about that touch down.

Debriefing

Seemingly some good points, turns were in limits etc.   then a note on the approach technique and that it basically wasn’t right, the result was one wing kept lifting and this probably played into why there was a ton of input to keep it looking reasonable.   But I got it kicked straight just before we landed and the landing itself was alright 🙂

We can refine the technique getting down, compared to my early crosswind attempts, I’ll take that landing any day of the week 🙂

 

Flights Cancelled by Wind & Cloud

November 4th, 2012 by PHC | Permalink

Recently I’ve lapsed on my general rule of booking 33% more lessons then I actually want or can technically make, it’s just been a busy few weeks and actually it’d been a pretty good run without a cancellation……but it couldn’t run forever.

So a couple of weekends back it was 25-35 knot gusting wind, scratching that lesson.

This weekend I was booked in for some less ‘sensible’ flying in the Extra 200, that was looking good all morning, but upon arrival to the aero club the Met Office had other ideas and within ten minutes wiped 2,000ft off the cloud base 🙁     What I really wanted to do with this session was some spinning, so for that we’d need a good few thousand feet, with the clouds down at 1,800 it was never going to happen.

So a couple of weeks of cancellations, but we’ll try again in a few days.   A couple of hours of blue sky can’t be too much to ask for can it?

Lesson 34: Short-field Take Off & Revision

October 15th, 2012 by PHC | Permalink

Having had a glance through the training sheet, I was semi-prepared for the tick box objectives of this lesson before arrival (though I have to admit I’ve not yet memorised the emergency procedures sheet quite as well as I should – equally I was expecting a slight grilling on this).

Briefing

G-MEGS Garmin 1000 Glass Cockpit

Garmin 1000 Glass Cockpit

With several of the clubs airplanes in for maintenance, it would be another trip in G-MEGS.   I couldn’t have timed finishing circuits and having a flight in the book for MEGS any better, now it’s playing to my advantage, as not all students are allowed to fly G-MEGS (I certainly went a year walking past it).   If I heard the instructor right, you need at least two solo’s – these are just club rules, but I’d guess the lack of analog gauge planes is causing other students some availability issues.

Found myself quite looking forward to another go in the glass cockpit aircraft.

The objective was to tick off a number of training boxes:

  • Short-field take off
  • Revision of slow flight
  • Revision of Climbing/Descending (with an emphasis on doing it at set speeds / rates).
  • Stalling with Flaps
  • Rejoining the circuit

Take Off

I’m quickly getting the impression that G-MEGS lives its life in tip top form, perhaps not getting the same abuse of trainee pilots like the other Cessna’s.

All pre-checks done, the plan had been to ask Air Traffic for permission to back track on the runway (taxi the wrong way up the runway in order to maximise distance for take off), with a plane coming into land and a mile long runway if we didn’t we might have got an immediate clearance.   I figured it’d still be more fun to do a back track and take off from there, so I requested permission to do it….  ATC as expected came back with instructions to hold…….once the Piper was down they were obliging to the request.

Lined up, with a full mile of runway ahead of us:  10 degrees of flaps set, toe brakes firmly held down, the engine was run up to 2,000RPM.    With the engine roaring, the brakes were released and the rest of the throttle opened……Everything that could be done to get this plane in the air in the shortest possible distance (apart from asking the instructor to get out), had been done and now we were charging down the runway and soon up, up and away.   Hope the kids that were at the airport enjoyed seeing this particular plane take off.

Climb out

Aiming for best angle of climb, this was done initially at 62 knots, before switching up to 80 knots once we were at a good altitude.   Really just to get some practice in flying best angle of climb.   Found the digital tape a bit easier to work with on this second trip.

Kept the climb coming up before starting a turn out to the right at 2,000ft.

Given the rubbish weather that had been forecast in the days prior, it was actually really nice flying.   A few clouds, but mostly blue sky and stable air.

Straight, Level……and Slow

My instructor asked me to fly at 70 knots.

I could just about remember that I wanted somewhere around 1,700 RPM to get this and it actually came together and trimmed up really nice.   2,500ft @ 70 knots.   Nice enough.

We did a bit of work with the flaps and various other speeds and familiarisation of flying out of the circuit.

Air Traffic Control were starting to get slammed by aircraft wanting to join or leave and we had a handful of planes to keep a look out for.  The Extra 200 was up (very fast, very aerobatic!), a Tiger Moth was around (very slow) and a Piper was somewhere in the area,  so lots to be looking out for!

Orbits at set speed

G-GLOC in climb

G-GLOC in climb

Just after being asked to make a turn, at 11 O’clock I spotted a planes wings 90 degrees dead flat to us, it was the Extra, doing a stall turn.    I must confess to now largely stopping and watching it complete the maneuver, they look good from the ground, when you’re altitude level with them, it looks even better……I have a flight in the Extra 200 booked for a couple of weeks time, started to really look forward to getting back up in that plane, sooo much fun!

My orbits were ok, I think the Extra distracted me a little, the first I lost ~130ft and that loss of height threw the speed from 70 to 82knots.   All generally ok, but I can normally orbit plus/minus 20ft.

Climb to 4,000ft

As we were about to revisit  stalling with the flaps down and stalls with flaps & power (approach configuration) it was time to climb back up, avoiding the clouds, to 4,000ft.   It’s been a while since I’ve been up this high 🙂

Found myself getting quite used to G-MEGS and the glass cockpit, once you get over the newness of it all it’s really quite easy to work with.

After an orbit to check the area for other aircraft, we did a stall with 20 degrees of flaps, with the nose and left wing dropping, it’s a fairly simple matter of pushing the control column forward, applying full power, adding some rudder and leveling the wings before recovering into a climb.

After another stall, I was asked to do one with flaps and power.   It all went fine, except I must have missed the request to recover on the ‘first sign’  (buffeting / stall warner), as I was on my way to letting it stall before the instructor said “Any signs of a stall?”       ……of course, oh right you want me to recover it already.   Fair enough.

Just to make sure, we did it again.

Descending at a set rate of descent

What goes up……… in this case, must come down at a pre-determined rate of descent.   Really just to polish up and check I could still do this stuff (it’s strange but I’ve been going round in circuits so much that it’s been months since I’ve had to descend for anything but approach to a runway).

First I was asked to descend at 500ft/min.    Seemed to get it all trimmed out nice for that no real issues and the stable atmosphere was no doubt helping the performance.    Next it was to try and make it 700ft/min.    This time the rate was wondering +/-50ft or so, but generally seemed a decent descent.

We leveled out at 2,500ft.

Just time to practice a few of those emergency scenarios I’ve not memorised enough, I think I had them in my head on run up to first solo, but now they’re slipping away, so some homework required 🙂

Circuit Rejoin

This would be my only “arrrh” moment of the flight, we got the ATIS information easy enough and my call to Approach was ok, they said to contact Tower and this was all good.   I then pressed the mic button to call the Tower and it should have gone like this:

“Cambridge Tower, Golf Mike Echo Golf Sierra, with information Alpha, QNH 999 hectopascals, request standard overhead join.”

Should have……but instead went like this:

“Cambridge Tower, Golf Mike Echo Golf Sierra, with information Alpha……….”

At which point my brain blanked out and my instructor took over to rescue the call.    I think the only issue here is I’ve not spent enough time familirising myself with the chain of events and when/who I’ll be talking to next, so I was trying to remember the who and the sequence and the sequences that would follow.

That screw up out of the way, the rest of the calls for joining the circuit were good and I was quite happy talking to the tower as we were put into a holding pattern over the airport due to traffic.

Descending on the dead side of the runway, it still surprises me how low 1,000ft feels when you’ve had an hour at 4,000ft.   Was a reasonable descent with an aircraft taking off as we were flying the crosswind leg of the circuit, just to keep things interesting.

Crosswind Landing

The weather was turning on us, from blue sky it was now an 8 knot crosswind, not far from the limits of a student.   I’ve spent a lot of time thinking through my crosswind landings, where they weren’t brilliant and consciously thinking about being more responsive.

Final approach was flown with the nose facing ~30 degrees right of the runway.

Leaving it a touch late to kick it straight (we were maybe 20ft off the ground), touch down was feather like and landings like this really put the icing on the cake of any lesson.

It had taken a bit of runway to get it all straight and calm, so ATC cleared us to back track and exit at Charlie, we could have got off at Delta but it’s a long old grass taxi if you get off there, so always grateful for their support.

Debriefing

G-MEGS External

G-MEGS

All in all a good and very enjoyable lesson, I know there were a few mostly minor bits I needed to tidy up, but I was happy with everything and the instructor seemed pretty happy, noting a decent landing in crosswind (he’s been in some of my more awful landings).

The weather is just about holding and/or I’m getting pretty lucky, it won’t last I’m sure 🙂

Lesson 33: First Navigation

October 1st, 2012 by PHC | Permalink

Arriving at the club, this would be a lesson of many firsts….

Finally allowed to leave the circuit, this would be my first lesson not flying in a rectangle for a loooong time, I can’t remember being above 1000ft without being told “watch your height…”.

G-MEGS External

G-MEGS

My instructor for the day was still out flying somewhere, so I was told to go and check out the plane, I’d be flying MEGS……..

Pardon me?   I could have sworn you said MEGS and must have misheard you……You’ll be flying G-MEGS.    They realise I’ve never flown MEGS before right?  Better check……Nope still flying it.

Ok then, G-MEGS it is.

 

Plane Checkout

G-MEGS Garmin 1000 Glass Cockpit

Garmin 1000 Glass Cockpit

So why the fuss about the plane, it’s a C172, so what’s the issue?    It’s a C172 with a Garmin 1000 glass cockpit.   All the bells, whistles, buttons and switches you could ever wish for appear in G-MEGS.

It was an option half way through learning circuits and an instructor thought better of it as there was enough to be learning without a whole new set of switches and lights.   So believe it or not, of the clubs 4 Cessna’s, I’ve never got to fly this one before.   Don’t get me wrong though, I’ve often walked past it wanting to one day have a go.

All those extra switches and lights require a different checklist, it’s fundamentally your standard C172 checklist, but now you have to check the G1000 isn’t detecting faults and dials now appear on the screen etc.   There are a couple of other buttons to press and as you can see below the yoke in the picture, there’s a million circuit breakers!

Briefing & Weather

Having had the slowest checkout of my life, with moments of “Where the heck is that..?”   I finally returned to the club house to catchup with my instructor and confirm we were going flying somewhere other than laps of the airport.   We were, Yaaay!!

The plan was to fly out, make a right turn, find “point Alpha” (a good reference starting point for bigger navigation sessions), do some radio work, request a QDM etc. and  come back for an overhead join.   Then it would be a touch and go, a left hand climbing turn out and then off to “Six Mile Bottom”  (it’s a small village East of the airport and has a good railway crossing a road landmark).

I forget what the actual wind was on the day, but if this had been a circuit lesson it would have been cancelled (greater than 10 Knots crosswind).   As the objective of this lesson was not about me landing, worst case the instructor could always do it, so the lesson remained on.

During the power checks another student, who from the radio calls had just been released solo, discovered the wind was to much and ATC called him back.

The digital RPM on the G1000 makes you faff with the throttle,  1722 RPM, but I want 1800….. that sort of thing.

Take-Off with Crosswind

The crosswind was so high that I asked the instructor “I think I’m doing this take-off….” during take-off brief.  A reminder to turn ailerons into wind and level them before rotation, but other than that yeah I could have a go.

Other than the crosswind that made for a semi-straight run, the take-off was ok.  The G1000 continued to have a “new toy” effect on me, rather than glancing at a gauge that is ballpark “80knots”, the digital airspeed just appeared to be all over the place, 72, 80, 84, 76, 80, 74, 81…….   I had a flash back to a previous lesson where the instructor said “You know what an 80 knot climb looks like…..so look out of the window and fly what looks like 80 knots!”    To that end I gave up on the digital display, looked up and started flying properly again.

Navigation to Point Alpha

Point Alpha

Point Alpha : Aerial Photo

It’s just basic maths, but it still surprises me how quick by plane you can be over a “nearby” landmark, which by car would have taken a lot longer to reach.

Such was the case with point alpha, I’d climbed up to 2000ft, turned right and within a matter of minutes (it felt like a handful of seconds), my instructor was asking “So let me know when you can see point alpha….”    Looking down and to my left, it seemed to already be there.   This is some sort of trick question, I’m going to point it out and then get told “ahhh everyone says that, but notice how….”    Nope, it really was point alpha – my god we reached that quick.

Strangely I’d looked at this point on my map a week before briefly, but hadn’t topped up on my knowledge of the surrounding area.   My instructor pointed out a few of the surrounding villages, I may have lived in this area for several years, but my geography is going to need work 🙂

QDM, QDM, QDM….

Now to see about getting Cambridge to supply us a QDM (Magnetic Track to a VHF Direction Finding Station), or in short:  “Which way should I point the plane if I wanted to fly to Cambridge????”

This is done with the syntax:

QDM, QDM, QDM…..<CALL SIGN> Requests QDM

The repetition is to allow the station being called sufficient time to get a fix.   They then reply with a bearing and a class of its accuracy, with “Class A” being +/-2 degrees.

Every radio call I was making was having me think twice as hard as normal, the new aircraft call sign: Golf Mike Echo Golf Sierra, kept making me think “remember what plane you’re in”.    I guess I’ve flown  Whiskey Kilo too much.

Compass errors

With that done, we set the heading bug and then went on to have a play around with compass errors.   To demonstrate how awful a compass is in a turn my instructor covered up the Garmin with his map (I’m used to flying with a map covering my instruments).

There was traffic in the area so ATC told us not to go above 3,000ft, we were at 2,200ft and if I’m honest my altitude keeping was a bit all over the show (+/-200ft), but I’m gonna blame the wind and the Garmin 1000 vertical speed tape that just seemed to be all over the place half the time.

Suffice to say the compass was once again verified to be rubbish in a turn, no awards for discovery there, but always nice to have a practical to prove it.

Touch n Go : Lots of Crosswind

Radio calls done to indicate we had the airfield insight it was time to rejoin the circuit, flying over the 05 numbers at 2,000ft and then turning back to cross the runway before making a descending turn – taking all the power off to get it down to a thousand feet.

Crossing 05, my altitude dipped to 930ft……I’d been flying nothing but a 1000ft for almost as long as I can remember, but suddenly with just 20 minutes up at 2,300ft, now everything felt really low.   It was a lot like driving at 70 mph and then pulling off into a 20 mph zone, feeling like you could just stop, get out and walk faster……..Now I almost felt like we were low enough to hit something, a double take that we were at 1000ft again.   Normal circuit stuff.

Such was the crosswind on final we were flying in with the nose 45 degrees off from the runway, and such was my concentration on attempting to make a decent show of the approach that I forgot to radio “final”  (400m out my instructor asked if I was going to…….arrgh).    If there’s one thing I’ve found in flying, it’s the ability for the mind to zone in on 1 task and forget everything else, it’s almost scary how focused you can become to the defeat of all else.

Don’t know why I bothered concentrating though, the last 50ft were awful and some instructor assistance was required to get it down with grace.   Crosswind landings have got to be a motor memory thing, I’m not reacting to the inputs quickly enough, there’s a reaction but because everything is reactive, the reaction and the amount of input needs to be instinctive…….and well, it clearly isn’t instinctive enough yet.

Navigation to Six Mile Bottom:   That’s a railway line?

Six Mile Bottom

Six Mile Bottom / Railway Line

As we climbed up my instructor told me to follow the railway line, my thoughts were “Ok I reckon that must be the train track…….but it must be one narrow train!”    I hope it looks wider on the ground, because it almost looked like a public footpath from the sky.

Again, no sooner was I convinced it was a railway line, the landmark I was looking for (road crossing the railway line) was insight – but self doubt kept playing in my mind such that I hadn’t gone “Yay there it is…..”    And we were over it moments later.

To try and put this distance thing into perspective, as the crow flies from the end of the runway to the yellow highlighted circle of Six Mile Bottom, it’s exactly 6 miles.

At 100 knots, subject to wind affecting ground speed, you’ll cover this distance in ~3 minutes.   However, you’re 2000ft up, a quick bit of crude math suggests that from 2000ft, if you look down with an angle of 10 degrees (or 80 from the planes perspective), you will be able to see a point 11,500ft away (2.1 miles).   Make that angle 5 degrees and it will be theoretically in immediate sight.

True Bearing, True Bearing…..

Just to get a bit of practice in, time to request a true bearing (also known as a QTE) from Cambridge.   This simply gives you the true bearing of the plane from the airport/station.   If you then fly the reciprocal of the bearing given, you’ll be heading to the station.

All done exactly as a QDM, but although it’s known as a QTE, the call is still for a “True Bearing”.

Time to head home

Calling ATC to tell them we had the airfield insight and request an overhead join, it was time to head home.   We were told to report when “overhead”  (2000ft and over the top of the airport).

Until my instructor spotted he’d turned off my RPM gauge (aren’t glass cockpits fun), I was flying for a while on the sound of the engine with my brain going “I’m sure the RPM was on the left of the display…..where’s it gone?”

Once over the dead side it was just a simple case of make a descending turn, down to a thousand feet and then it was as my instructor put it “back in your normal circuit”.     Yay the safety of the circuit, how I’ve missed you these last 55 minutes 🙂

To help keep the speeds up and maybe make it all a bit better, tried to do the landing flapless.   I may have remembered my radio calls this time, but the crosswind was still relatively immense, my attempt at landing in this much crosswind was, well, rubbish.   Time for a little help from someone who knew what they’re doing……

G-MEGS all turned off

G-MEGS Shutdown

All that being said, after months and months of going round in circles, this was an enjoyable lesson.

Finally have all four Cessna’s in the book, so maybe I’ll get to fly it again from time to time now.

Milestones & Statistics

September 23rd, 2012 by PHC | Permalink

A cynic once said:  There’s only a person in the front left seat of a plane so there’s accountability should it crash (otherwise you’d just let computers fly it, human error is one of the greatest causes for plane accidents)……..to that end, a lot of emphasis is placed on pilot experience and that experience is traceable primarily through their log book.  The integrity of that record is held against the pilots integrity and as such each and every page of a log book is signed by the pilot as being true and correct.

Downside is paper records are rubbish for keeping live totals & statistics.    Therefore to date I’ve never bothered totaling up my hours flown, how long it took before I went solo, which planes I’ve flown the most….. etc. etc. etc.

Upon completion of circuits, which I consider a milestone, I decided to sit down, type it all up and see where we’re at with the numbers:

Total Flight time to Solo 19 Hrs 45 Min
Circuit Time to Solo 10 Hrs 9 Min
Total Duel (to date) 26 Hrs 15 Min
Total Solo (to date) 3 Hrs 20 Min

They say the average is to go solo somewhere around hour 15, sure I’m past that, but I never said I was doing this to set records.   I’m to busy to fly every week, but if you want to tick boxes in the shortest time possible, I’m sure that flying 3 and sometimes 4 times a month is the key.

Solo Time is an interesting one, remember when I didn’t ask how or why I was back to 40 minutes still to fly in my final circuits lesson?   By the numbers in my log book I was actually at 2.5 hours before setting out on that final lesson solo, but if I don’t include my first solo (15 minutes in the log book) in the count towards 2.5 hours. Then on that final lesson I had exactly 20 minutes left to get, which ties up with a previous debrief.   So I think somewhere communication wires have got mixed up and I went out to get 40 minutes (and got 55), when I needed only 20.   You won’t hear me complaining, flying solo is a lot of fun!   It’s what the whole show is about….

Aircraft Flown

Nothing here came as  much of a suprise:

G-SHWK
18
G-HERC
12
G-UFCB
8
G-GLOC
1

Note this counts solo & duel sessions seperatly, so doesn’t give you number of lessons if added up.   I’ve also strictly only flown G-SHWK 17 times in the day, one was a night flight and my time in G-GLOC was spent mostly upside down 🙂

Average Flight Time Per Lesson

This comes in at 55 minutes.

So at this particular check point in the flight training, those are the numbers.  If nothing else it might serve as a ball park estimate for anyone learning at a similar rate what it’s going to cost them to get to this point.

Lesson 32: Circuits Complete (Solo #6)

September 19th, 2012 by PHC | Permalink

If the last lesson was booked on an adrenalin rush, with completing circuits within reach, this lesson was booked because the weather forecast screamed “Last chance!!!”.

As predicted, the weather on the morning was glorious sunshine, no clouds but surprisingly a 10 knot wind.   Unlike the last lesson though, this time it was straight down the runway, giving a cross wind of almost zero knots.   Perfect for flying.

I’d been grabbing cancellations and booking more lessons then I really should have all over the place through August.   With only a handful of minutes of solo circuit time remaining, I was very conscious that financially, it might be now or never to complete circuit flying (…..well, given I might never get the weather again this year, it felt like it might be now or never).   No pressure then!

Briefing
Flying with an instructor who so far, had never sent me solo before.   I didn’t know the hows and why’s, I didn’t ask, but some how I was back at ’40 minutes of solo time required’.   So the mission statement was pretty simple:

In the least number of circuits possible, impress the instructor enough to send me solo for maximum time.

Sounds simple right?   But I knew historically, my first circuit, especially one at 9am, was not typically my best…….today it would have to be!

I didn’t want Charlie Bravo again, to much was staked on this lesson to be messed about by the ‘airplane’.   So just to be sure, we took G-HERC (Romeo Charlie), it’s been historically very good for me on solo time.

A quick re-cap of circuits for non-pilot readers of this blog:

Taxi & Take-Off

G-HERC (Golf Hotel Echo Romeo Charlie)

G-HERC (Golf Hotel Echo Romeo Charlie)

With the plane checked out the instructor jumped in and went through her general plan of attack:   We’d do maybe two circuits, she’d say nothing, see how they went and then hopefully she’d be getting out and I could go and get my solo time.   I’ve never been sent solo in two circuits before, so now they’d really have to be good right out of the blocks.

All pre-checks done and with a queue of other Cessna’s all not very far behind us in their checks we made a dash for holding point Alpha.   The radio calls started coming in “Charlie Bravo…..request taxi.”,   “Whiskey Kilo……request taxi”.  It’s going to be busy in the circuit this morning.

Lined up on the runway and cleared to take-off, I always make one final check with the instructor if they’re happy.   With that, full power on and Romeo Charlie begins its charge down the runway.

It begins to climb at 60 knots and pushing in some right rudder we begin what turns out to be a really nice straight climb up – looking good so far at least.

Circuit #1 & #2

That climb really set the trend, the air was really stable and downwind was as smooth as anything at a perfect 1000ft.

Turn on to final and approach on circuit one was almost as perfect as I’ve ever done, all flaps down and radio calls done I just needed a good last 50ft (I’d go around if I had to, but I really wanted to get this right).   It wasn’t a perfect landing, we flew along the runway longer than I’d have liked, but when it touched down it was pretty reasonable.

With a vote of confidence about the landing from my instructor, I pressed on with circuit two.   A few minutes later I was told:

“We’ll make this to land…”

That could only mean one thing:   Don’t screw up this next landing and the solo was on!!

We touched down off circuit two with a bit of a bounce, nothing special but it made me grimace a little, it could have been better – there was a lot riding on that landing.  Should I have gone around?  Was I pushing it too much?    By the time all those questions had gone through my head, we were approaching the turn off point and my instructor was suggesting my flying was perfectly safe to be sent solo.

One tick in a box……now I had to go and do it four more times, on my own.

Solo Flight Number #6

My instructors last words were a reminder that I might only be minutes away from completing circuits, but if the weather did turn or the wind picked up, or I wasn’t happy generally, land it.

With that, I was on my own in the plane.

There’s a wonderful moment, about 15 seconds after the instructor gets out that is almost worth learning to fly for all on its own.   Without experiencing it, words can’t quite describe how brilliant it feels to be at the controls of a plane, on your own, about to take off into the skies…….it’s just special and I’d recommend it to anyone (though be warned, it’s highly addictive).

Taxi clearances done it was off back to holding point Alpha.   I realised about halfway there I was taxing a bit quick, so I backed off the power.   What was I rushing for, I had a clear 50 minutes of lesson time remaining and if I ‘borrowed’ the plane for ten minutes into the next persons lesson,  I don’t think anyone would have minded too much.   With blue skies and perfect wind conditions, I wanted to just enjoy this flight.

Solo Circuit #1

With so many Cessna’s in the circuit, it was no surprise ATC told me to hold, I watched Whiskey Kilo cross the threshold and do a very nice touch down.   I have no idea what my landings look like from outside, but I want to bet a good percentage don’t look as nice as whoever did that one.

I knew that two instructors who I’ve flown with (and have been previously sent solo by) were now in the circuit and they might be watching to see if my landings solo, were remotely like that one, for all I know one of them did it just to show me how it’s done 🙂

ATC came back and cleared me to line-up behind the just touched down Cessna, once they were back up at around 600ft, I was cleared for take-off.

These are the other few moments which words will never do justice, a mile of runway before you, all the power on and you’re soon charging down asphalt.   If you weren’t concentrating on airspeed and keeping the plane straight, you’d be overexcited with the thrill of it all.

The circuit went sweetly, a 1000ft, no wind and nice stable air.  ATC told me I was number two for my touch and go.   I decided I’d do the first few with flaps.

Touch down was almost good, just didn’t quite get the nose up enough and touched down with a slight bump.   Fingers crossed that looked alright from the tower.

Solo Circuit #2

With so little wind it was just great flying, the only planes around were the other two Cessna’s, all from my aero club, so it was sort of fun to be flying around with other club members.   Even though we really weren’t involved with each others objectives.

Another ‘with flaps’ landing.  If anything this was a bit of a rubbish landing,  I don’t look back and think I should have gone around, it didn’t need that, but I know I could have done it better.

Just to keep things interesting a radio call from one of the other Cessna’s indicated that another instructor was about to get out and soon there’d be two students in the circuit!  (I won’t hit you, if you don’t hit me 😉 ).

Solo Circuit #3

I needed to get a really good landing on the books, something that was feather like on touch down, just for my own sake and to bring back some of that excitement that comes from a perfect landing.   With that in mind I knew my best landings come from landing flapless, so I decided to extend downwind and come in flapless.

However, the radio call gaps told me someone wasn’t as far behind as I’d like, so I couldn’t extend to much or I’d mess up everyone’s horizontal separation.

In all that thinking and listening to others radio calls to try and get a good picture of how far they were behind etc. I nearly jumped out of the seat with a moment of “Arrrgh, downwind radio call!”  

About 1 mile out on final I realised that if I did nothing, I wasn’t going to get this plane down in time.   Rather than come in to high and have to abort it late, I decided I could take flaps now (well within the white arc, flying 70 knots) and I’d get it down.

With flaps it really came down, the sink over the last mile made me think if I’d just stuck with it I might have actually got it down without flaps.   A mental note for later….

Touch down was with a fairly hard thump, that was three that personally I felt were a bit average and I was starting to ponder how the first two with the instructor had ever been as good as they were.   Really needed to get a great one in the bag.

Solo Circuit #4

Now I wanted to do a flapless landing more than anything.   I was still conscious of others in the circuit, but I’d had a re-think:   I’d extend my downwind, so they might catch-up a bit, but I’d also be flying the approach at 70 knots instead of 65, so it should all sort itself out ok.

To land or  not to land, that was the question.   I had a clock running in the plane and it was showing 37 minutes, by the time I landed it should be over 40……but what if it wasn’t?   I really wanted to get this done now and not have to come back up with an instructor just to get 1 more circuit solo done.   I figured if I’d ran out of time and they wanted me to land, ATC would tell me, so I called “downwind, for touch and go….”   Might as well max out my solo time if I can 🙂

Turning on to final I initially thought “damn, didn’t extend enough……too high again!”    However, this time I wasn’t so quick to bail on the flapless approach, I kept just a touch of power on as it helps the stability and then told myself “It’ll come down……give it few hundred more meters….it’ll come down”.  This wasn’t wishful thinking, as noted on circuit #3, by about three quarters of a mile out there’s a significant period of sink.   So I might be staring at four white lights telling me I was to high now, but I was pretty confident they’d quickly become two by half a mile out and then we’d be good to go.

Sure enough it came down really nicely, three white one red, then two and we were now on a nice 3 degree approach at about the right time.   Crossing the threshold the sensation of having time and everything feeling calm and slow is the give away feeling that it’s going to be a nice landing.    With a really gentle thud, the main wheels touched down and I lowered the nose.

That is how to land a Cessna 172……. hope someone was watching 🙂

Solo Circuit #5  –  Time to Land.

With good landing in the bag and knowing the clock would be well over 40 minutes on this circuit, I called it to land.

The Cessna that was behind me had aborted its previous landing so was doing a pretty good job of catching me in the circuit and they wanted to now land as well – better not overshoot the touch down then had I.

All flaps down, it was looking perfect and was going to be on the numbers.   Still looking perfect, still looking perfect…… Thump, the back wheels hit the numbers but hit hard and the plane bounced back into the air, all of about 5 ft, before coming back down on its main wheels and I could then lower the nose wheel.   It was never a balloon, there was nothing like enough lift, but it had gone from a really pretty landing, to a moment of “arrrgh how did that bounce?”

Still we were down and Air Traffic gave instructions to vacate at Charlie, all easy enough.   It’d been a really good morning of flying.   I looked at the clock:   48 minutes of solo flight time, it was undisputable, I was done with circuits!

Parking :  Wooow Parked properly.

Here’s a weird thing about learning to fly:   You wait to fly solo and by the time you do you’ve done take offs and landings without a word from an instructor, many, many times.

Not once do they say nothing when you’re trying to park the thing.    So the first time you’re on your own to try and park it, is when you solo.   This has meant that I’d so far had a total of just 5 goes parking a plane properly (by this I mean straight and aligned with all the others AND able to get the tie downs to reach both sides), they’d all been pretty rubbish.

This time I was determined, it was going to be perfect parking.

I made sure I was perfectly straight as I stopped the nose wheel on its concrete slab and triple checked the left wing to make sure it was about right for distances to tie down (the tie downs only just reach at the best of times).

Returning to the club house my excited announcement to all around wasn’t “Wooow finished circuits.”   Instead, it was a rather more random burst of excitement:

Yaaaay!   I parked the plane!!!!    …….and flew some solo 😉

……Next Lesson, time to look at leaving & re-joining the circuit.   Who knows, maybe even a map will be required…….that’s if I can remember how to fly anything but rectangles, I’ve done quite a lot of it.   I’ve got quite used to looking down on Cambridge Airport from a 1000ft, it’s going to feel weird not to have it within sight!  🙂

Lesson 31: Circuits with Cross Wind

September 8th, 2012 by PHC | Permalink

This all came about from the adrenalin rush of being within touching distance of ending circuit flying and being allowed to go somewhere, anywhere, other than round and round the airport.

Had I been thinking sanely I may have spaced this lesson out a bit more, but the counter-risk if you do, is you might not be “as good” next time you get in the plane.  I’ve had my share of feeling like an hours flying was actually just one small step backwards for man.

The aspiration then was to get signed off to fly solo…..then get the remaining minutes of solo time in the bag.

The wind had other ideas…….

Briefing

G-UFCB Cessna 172SP

G-UFCB : Cessna 172SP

We’d take G-UFCB….   Historically, this plane doesn’t like me, so not a great start.

Crosswind was at 7 knots, 90 degrees to the runway direction (Arrgh!) and gusting up to 9 knots.   Right from the start this was looking questionable.

So questionable in fact that the idea of doing circuits was scrapped by the instructor and instead the plan was to set out and do the beginnings of Nav.

I’ve been going round in circles for so many lessons now that the opportunity to go somewhere, anywhere else was very appealing.

Aircraft Checkout & Change of Plan

The wind didn’t seem that bad while checking out the plane and either the instructor got told to scrap his plan and not take me out of the circuit until the boxes had been ticked.   Or he to was thinking it might just work….

All checked out and taxi clearance granted,  we were off pretty quick.

Circuit #1

There are some lessons I can remember every second, others (normally the ones where it goes wrong), I can’t remember what happened, when.   As this is one of the latter, you can conclude it didn’t really go that well.

The wind successfully blew me left of track on the climb up, not a great start but the rest of the circuit was ok, bit gusty but no worries, it was a 90 knot, 1000ft about as good as they come circuit.   Turned to early on to final:  When there’s a solid cross wind this is easier to do then it sounds, because you have airspeed but your ground speed is rubbish, so if you start a turn at the same point as always you’ll complete it having had a tighter turn relative to the ground.   Think of it like driving a car, if you turn the steering wheel to a set point, the tightness of the turn and therefore what you’re facing after 90 degrees of turn, depends on your speed, slower you drive while turning the tighter you can turn.

All things considered the landing wasn’t bad, I got the usual comment:

“a bit more back pressure”

Considering I’ve done a million circuits and I’ve been solo now five times, I find myself bemused at still getting this comment.   There are moments I wonder if these landings are any better than the first landings I ever did?

I look back and I think this comment was the death of the lesson, I would spend the next 50 minutes trying to improve this and the more I moved away from flying it “my way” (Whatever that is), the worse it all got.

Circuit #2

Much better climb, compensated for the cross wind and stayed on track this time.

The turn on to final also got the correction treatment, the landing however in my mind was forced down and the attempts to get more back pressure on the controls lead to quite a high nose attitude, the stall warner going off still about 20ft off the runway and basically the last 50ft felt like a total mess pulled together.

A positive was that when it did touch down, it did it quite softly.

The Other Circuits

I’m going to keep this short, while I generally enjoyed the flying, this lesson makes me grumpy.

Just before turning base on the next one I was asked to do it flapless, I should have known from that far out I’d never get it down with no flaps……I didn’t, we were still 300ft above the runway upon crossing the threshold, so we aborted.

The rest were progressive levels of rubbish, hard landings, all over the place landings.

Hindsight is 20:20, but lessons like this are where you need it to be called quits early.   The objective right now is not to tidy up this or that, we didn’t come up here to fly cross winds or tidy up cross wind landings.   It’s to get solo time in order to tick that box and move on.

Waaaay back when I started, one of the head instructors used to occasionally sound really fussy to me about not wanting to send other people in borderline conditions for the objective they were there to achieve.    I even had a few lessons cancelled where he’s said “You need solo time, you won’t get it in weather like this, so there’s little to be gained from being with an instructor at this point…..”    You start your training thinking this all sounds a bit pessimistic, but I’ve now come to conclude that this is a voice of experience.

I’m going to leave this post positive though, my crosswind flying is better now then it once was.

 

Human Factors Exam : Passed

September 3rd, 2012 by PHC | Permalink

To give the exam it’s full and proper name:  “Human Performance & Limitations”, not one I’d been really enthused to learn, but it exists for good reason so my plan of attack was to crack on and get it out of the way “early” in the chain of exams and then have one less to worry about and be able to focus on the bigger topics of Meteorology & Navigation.

The club said most people tend not to use the full 30 minutes.   I think I was done in around 20, then spent 10 checking the 3 questions I was a bit on the fence about and re-checking the entire paper for anything really silly (like starting from question 2 etc.)

I returned to the club admin office literally to the second of the 30 minute alarm going off, perfect timing 🙂

………and the result?      90%

I got one question rather embarrassingly wrong (a moment where you realise what you’ve done about 10 minutes after getting home, doh!).   The other, I have no idea and I think it’s best we leave it that way.

Now to open up Meteorology.    It’s moments like this you realise teachers at school were trying to teach you something you actually would use later in life 😉
