 |
|
having done many, many aileron rolls and aileron rolls in sequential
groups... in such aircraft as the Navy-Beech T-34 Mentor, M-D A4
Skyhawk... and some in the 2-hole Pitts Special. and others... and...
the C-172 and... yes 'even' the C-150... my experience has shown me...
[keyword ME], that high drag aircraft, with slow roll rates will have,
at best... a pronounced nose low attitude upon recovery. and an
immediate reduction in power is required in an attempt to avoid Vne once
on the recovery side of being upsidedown. it really falls fast in the
last quarter off the upsidedown portion of the roll recovery in a high
drag airframe... and it has been as such Every time!... a big wallow in
a high drag, slow roll bird... and nose low and gaining speed or if done
wrong... slow and approaching an upsidedown stall... to me every time i
have attempted or completed such an event in a slow, high drag airframe
i can only consider it to have been a dangerous maneuver. hardly a safe,
acrobatic maneuver.
no doubt it can be done... and one can wallow thru it... given imo, more
braun in the cockpit than a sense of cool smarts...  but clearly it is
a DANGEROUS maneuver. " kids, don't attempt this at home!"
in fact, tonite on local 6pm news last item was pix of the acro pilot in
brazil or some place close... high and tight... rolling, flipping,
zipping and all this and that at an airshow... wow... and then... NO
MORE air! " ouch " and he bot the farm in full view of the crowd. even
safe things can get dangerous... and rolling slow, high drag aircraft is
always dangerous...
ymmv, but i am not so sure...

Normally in a low performance airplane you would get some speed, raise the nose 20 degrees, then do your aileron roll. The slower the roll response the higher you raise the nose to start; that way you won't exceed Vne on recovery. The nose should end up only slightly nose low; not 30 degrees nose down.
