 |

Michael,
please discuss with your flight advisor, I would do a step up approach
first with 60% power to get a feeling (and start enough high).
My Glastar does exactly the opposite to what you describe (and I can
repeat it) so the outer wing stalls and the plane goes into a straight
and level attitude with nose down, very tame.
However I did hear from Lancair/Glasair pilot from wing overs! (Andre
Beusch might be a good person to talk about his experience.)
Good luck (and I'm impressed with your landings, seems the 10 has a lot
of elevator authority on slow speed as well as that nose gear is up
about half the runway long 
Cheers Werner

My test program asks for a full power 30° bank stall.
M question is if this has been done by others and what is the aircrafts behavior. I'd expect that the low wing would stall first due to lower airspeed compared to the outer turn wing.
What did you experience?
Thanks
Mike

John,
the idea behind that point is to simulate a large bank on a go around.
It should not be done that way, but in Switzerland the test flying
includes that program point.

I'm thinking that the test is just a plain accelerated stall ..... and the stall should be occur about 20 knots above straight and level stall speed.
So, at some comfortable speed 90 to 100 knots .... roll into the 30 degree bank and apply back pressure to hold altitude. The airspeed should decrease as you add back pressure until the stall occurs. Different airframes act differently. Some will roll to the outside of the turn and some will just drop the nose and roll to the inside. Let us know if that satisfies the test and what the resulting unusual attitude you get!!!
I may be wrong, but this is my take.

Flaps should be up for most any scenario including missed approach or go around, as there should be no turning before flaps are retracted.

Technically yes it's an accelerated stall but at a 30 degree bank the load factor is only 1.15, so stall speed should go up 7.5% -about 5 kias.
