"Flat spin" within approved envelope?
#11
I guess you kept that one to yourselves at that time. IIRC it has something to do with the T-Tail.
Boredom, confidence, and complacency can bite you. Just an interesting parallel factoid - Mooney's are not approved for spins either - NOT that I'd have any knowledge of that.

Holy crap! That's incredible.
For the seasoned CFIs out there, would you recommend always loading the plane to utility category when doing any air work?
My concern is that while practicing stalls with a student, we could enter a spin in a normal category loaded aircraft which could prevent a recovery.
Thoughts??

Careful how you phrase this stuff no brakes, once spinning simply pushing the stick forward will only accelerate the spin. I think you are referring to much earlier, at the innitial stall. The best advice on these matters is to consult the good ole' POH.

MoeRudda,
I'm sure what JamesNoBrakes meant was to relax back pressure immediately as part of a "spin prevent" (as the USAF used to call it in the T-37). The T-37 would wrap up pretty quick if you tried the "spin prevent" when it was already established in the spin.
The main point is that you need stall + yaw to get into a spin. If you stop either immediately, before the spin is established, recovery happens quickly. Last month I did 22 "upset recovery" flights in our F33C aerobatic Bonanza, with slipping and skidding cross-controlled stalls each time. The plane recovers immediately if back pressure is relaxed and rudder/ailerons placed to neutral after the initial "snap". If back pressure is held, it can get interesting...

Yep, I was trying to answer the CFI that was stating "what if I'm doing stalls with my student and...". I was trying to say that with decent knowledge and skills, it should never get as far as a spin. Also, every plane does recover differently and I'm not sure if Moe Rudda has spun an airplane where the rudder is not effective at stopping spin rotation, as opposed to some aircraft that are designed with extremely effective rudders that get airflow easily in spins (basically the opposite of skycatchers, haha). Pushing the stick forward slowly does result in spin acceleration, but there is so much more to it all I also happen to see a lot of (unfortunately) people that attempt to make an aircraft spin "better" by employing a variety of techniques that are not IAC with the approved procedure. While some may be relatively harmless and only serve to help the aircraft into a spin, this general idea and operating method could be hazardous if you don't understand the effects or get an outcome that was unexpected. It's usually the crowd that doesn't really know what their doing but they "heard this works".
Used to fly those aerobatic bonanzas! How are the wing-spars holding up?

PLEASE READ THE ABOVE STATEMENT!
GO GET SOME TIME IN A PITTS and see what the "stick forward" will do for you in a spin.---NOT A GOOD THING!
