spins from coordinated flight

If you then ask a student to explain the aerodynamics in play as a spin
develops, it's THEN you want the auto rotational aerodynamics.

Different approach. You, as a military pilot (as I think to have
understood), believe in the behavioristic approach. Me, as a scientist
(and amateur pilot) follow the cognitive approach. Your approach yields
pilots who exactly know what to do in this or that situation, but
probably without really understanding the deeper reasons. My approach
tries to understand the underlying physics and to deduct the needed
pilot action from there. Not nessecairy for a pilot, but it's my style,
I think it's interesting and it's the prerequisite if you want to go on
your own feet beyond the tought stuff.

Now if only that fog around here would go away so I could go and rent
that Cap 10 and do some spins...

I don't know of any autopilot that could be programmed to fly an aerobatic
maneuver based on predicted actions. Yet an autopilot can be designed to
observe and respond to the observed dynamic actions of the airplane.

I don't know of any autopilot that could be programmed to perform
rolling circles, either. But where's the relevance?

Flight is an art based on a science.

Well...I could say that your comment above is a deep personal insult
(which it is BTW :-) but in this case I will respect the fact that you
simply don't know anything at all about me since you have assumed I am a
military pilot which as half the world knows couldn't be further from
the truth.
I am in fact simply a civilian pilot who has flown military airplanes.
It's as simple as that really....oh yes...there is one more
thing....I've spent about 50 odd years directly involved with the flight
training community as both a CFI and an adviser and consultant at levels
ranging from primary training to teaching people to fly the highest
performance airplanes in the world.

If you surmise that the people I have taught to spin airplanes "probably
don't understand the deeper reasons" involved that YOU as a scientist
can provide, or that the pilots I have trained don't know thoroughly the
complete aerodynamics involved with spins, I fear you are in for a deep
disappointment :-))

We just present these things when it is correct to present them and not
when another explanation is the right explanation :-)
