More practise...
I was originally going to do the last of my requirements
with Lee today, but Lee wasn't feeling too great, so I did a solo session
instead. Today's writeup will be short! I went out and practised slow flight
and ground reference manoevers (but there wasn't really enough wind to make
the ground reference work a real challenge!). I also did some steep
turns.
I tried one new thing, prompted by the "turn back/don't turn
back" debate that keeps appearing in the newsgroups. This is the debate on
whether you should try to turn back to the runway if your engine quits after
takeoff or land straight ahead instead. I made the "deck" at 3,000 ft. -
a good safe altitude in case I stalled it, then got the airplane in a takeoff
attitude and applied full power, and climbed out at 75 knots (a hair over
Vy). At 500 ft. above the deck (3,500 ft AGL), I pulled the carb heat out
and pulled the power to idle, then waited 3 or 4 seconds to simulate the
engine failure. At this point, I put the nose down and achieved best glide
and trimmed the airplane to hold 65 KIAS. I then did a teardrop turnback
as if going back for the runway, trying to keep the airspeed as close to
65 KIAS as possible. Once back on track, I had lost almost exactly 500 ft,
and that was without the stress of the ground being close by, and never exceeding
70 KIAS or slowing below 65 KIAS. I think it would be a good idea to add
another 200 ft. to this figure (especially since this was a controlled exercise,
with the aircraft being nowhere close to gross weight).
Conclusion.
Just a little more practise... I've got some time scheduled
with Lee to make sure that all the requirements are met.
What was learned.
It's surprising how much altitude you can lose in a teardrop
turn using best glide and no more than 40 degrees of bank. No wonder you
keep hearing about stall/spin crashes when people try to turn back - the
look of the ground coming up can easily get a pilot hauling back and stalling.
My plan is to land straight ahead or use small deviations unless I have at
least 700 feet.
Date & Time: Sunday, 7th September, 1997, 18:00 CDT

Instruction: 0.3 hrs solo. Running logbook total: 55.2 hrs, 23.3 hrs solo
Aircraft: Beechcraft BE23 Musketeer, number N5977S
Taking a ride with Murphy in the left seat.
You've heard of Murphy's law - if anything can go wrong,
it will? Well, Murphy was here today. In the morning, I went out to fly,
but the weather report wasn't that great, but at least it was reasonable
VFR. However, the weather report of 7 miles visibility didn't match what
I could see as I drove to the airport. I called it off - it was clear that
the haze was too bad (more like fog) and when that started to clear, murky
grey floated at around 500 ft. I rescheduled for the afternoon in the Musketeer
since the 172 was booked up solid, and revised the C172's operating
manual.
The day continued to be gray and murky. However, it did clear
up nicely when it was my time to fly. I preflighted and got fuelled up. Lee
was at the airport lounge - he had family in town and he'd taken them out
in his C182, and they were having a pizza when I came in, so I got something
to eat into the bargain!
The preflight went fine, except I couldn't find either the pitot
cover or the laminated checklist, so I had to use the aircraft's POH and
use the checklist in it (pretty much the same as the plastic one, but the
wind kept trying to blow the pages over on the book!) I got to the run-up
pad, and did the run up. Power to 2,000 rpm, right mag - uh oh, 300 rpm drop
and lots of roughness! The left mag was smooth. It sounded like it was running
on 3 cylinders on the right mag. So it was time to ground the airplane...
So the nearest I got to flying today was the runup pad at the end of runway
13.
Conclusion.
These things happen. Just reminds you why you do mag checks
- although mags fail very rarely (I was unlucky to suffer a mag problem today)
- the runup check is extremely important. Always do it!
What was learned.
Once again exercising good judgement. Firstly, excercising
judgement about the weather - although it was MVFR and legal...it turned
IFR so the correct choice was not to fly, despite DUATS briefing before I
went - my eyes were a better weather reporting device this morning! (I always
get a DUATS briefing for a local flight, and both DUATS and call WX-BRIEF
for a cross country).
Then the sick mag...there was only one choice, taxi in, shut
down and call the owner (who said he'd come out and look at it this evening).
