lesson report

Hi Oz, I'll bet it will drop a wing fast if you have power on and
full left rudder (you probably shouldn't do this as it may be way too
violent -just a little left rudder should be enough), but you have to
stall -not just take it to the point where the stall warning goes
off. But, do you actually stall or only just slow to near Vs -your
description did not sound like a full stall?

Hey Mark!
If the fpm shows a loss, that's a stall yes? It started to show below
level, at which point I lowered the nose. The horn had been activated
for a few seconds already. The Gazelle stalls at about 45kts, and I was
definately not doing anymore than that, so I'd say it was an actual
stall. Next lesson is supposed to be advanced stalls so I'll get more
practice in then.
You may be right about it dropping a wing with full power and full
rudder. I was originally told it would not do it, but I guess that was
with a power off stall.


Hi Oz

No, a loss in altitude is not necessarily a stall demonstration. You
have to try to maintain height by pulling back more and more and the
stall will show itself as a sudden nose drop -you may be at full back
stick before the drop occurs. This is because the center of lift
suddenly moves back as flow separates. In the PPL you are expected to
hold altidude accurately until the abrupt nose drop. The actual stall
speed depends on loading and the POH figures should be for MTOW. If you
are not up to MTOW, the stall will be below Vs (remember bank increases
wing loading). Height loss could be as little as 50' if you do it well.

For the wing drop 1/2 power and small left rudder should be enough -you
don't want it to snap into a spin! The wing drop exercise gives you
experience in immediate reactions needed to stop a spin developing. I'd
say it is probably the most dramatic manouver I've done so far (recovery
from unusual attitudes under IF seemed less dramatic -maybe because I
couldn't see the ground!).

I hope you've covered the spin break method -PARE (and remember you must
pull back rather than forward if you've become inverted :-( ). I'll
admit I've not had the confidence to do a full wing drop while flying
solo so far -even though my recoveries to all 3 stalls have been quite
good (IMHO). It can't be due to the 'confidence prop' in the right seat
can it??? By the way, on my checkout for soloing to the training area I
managed to drop a wing a bit during an advanced stall. My immediate
rudder action killed the problem and I got my first compliment :-) -so
training does seem work -even though I'm still finding good rudder
coordination elusive... only 10Hrs to go before PPL minimums... Tomorrow
is low flying lesson 1 -I'm really looking forward to that one after 5
hours under the hood!

Hi Mark,
I'm not doing PPL, I'm doing RAAus, which is ultralights. I asked about
spins last weekend, and was told we won't be covering them. I asked if that
was because the a/c just won't spin, and was told that you could probably
force it to spin, but you'd probably rip the wings off at the same time.
Spins are classed as aerobatics, and my little a/c is not approved for
aerobatics.
I'm 3 hours from RAA minimums (20hrs)
