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)
