on a side note, can an instructor without an aero endorsement teach (or even demo) incipient spin recovery? Or a stall off a climbing turn?
reason I ask is, if aerobatics now means:

(a) bank angles that are greater than 60°; or
(b) pitch angles that are greater than 45°, or are otherwise abnormal to the aircraft type or
(c) abrupt changes of speed, direction, angle of bank or angle of pitch.

surely such stall training could come close to falling under some of those criteria (particularly (c)).

Genuine question.

That's it, djpil, not longer a student, but happy to stay sharp by practising those manoeuvres every now and then, hence (the legitimacy of) the question.

Oh dear, there’s always one peanut in the crowd that thinks the prop will always keep spinning :-(

And I do apologise for being that peanut.

But I would appreciate the benefit of your experience and obvious wisdom.

How does a peanut like me get the propellor to stop spinning if it’s attached to a hot Lycoming or Continental in the air? I know from first-hand experience that it’s not by turning the fuel off or the magnetos off, or both.

Pull the mixture and hold in level stall till it stops ..... re-establish glide and use starter to get it turning again - when you're ready - or do a dive and see what speed autorotation commences. Over an airport may be prudent.

Yeah the stall sometimes works, but it’s amazing how long you have to hold it there before the windmilling ceases. And sometimes other stuff happens that means the level stall can’t be maintained!

If you stop the VW in a Starlet nothing will get the prop to turn to airstart. A couple of interesting forced landings, at least one in the water near Rottnest attest to that.

Probably not a great idea for a hot Lycoming or Continental when it may need to be restarted quickly.


Once you pull the mixture inflight, your Lycoming or Continental is not going to stay hot for long! :eek:

The CHTs tend to take quite a bit of time to cool down. Not much difference from pulling the throttle to idle.
