I also remember doing some training in a 152 (I think it was a club checkride) with the then Chief Pilot of Marshalls. He suggested that we try a full power stall. As I was setting up for it, I asked "So what am I expecting to happen then?". He turned to me and said, in his inimitable deadpan tone, "I have no idea, I've never tried one before."
That sounds like the people I trained with!
Seriously though ... knowing that the only stupid question is the one I don't ask ...
I sure I recall being in a little aeroplane with power on (don't recall whether it was full or not, don't recall the flap setting either, er, not very good at this am I) and the stick back as far as it would go and the nose pointing at the sky and the thing simply refusing to stall. In that the warner was blaring away, but the nose didn't drop and a wing didn't drop and whilst we weren't making a lot of forward progress we weren't making much downward progress either. Sure the wings must have been at least partly stalled, but the thing was still flying after a fashion and we decided it wasn't a "stall". So, as the thing wouldn't "stall" in this configuration with this power setting the instructor decided that it was reasonable that I'd failed to demonstrate a recovery from the non-existent stall!!
So, the stupid question is:
Are there ranges of configuration and power setting for particular aircraft where this behaviour is expected - it stays upright, mushes along vaguely forwards, nose doesn't drop, wing doesn't drop, no more elevator to bring into play?
