Stall characteristics may also be too 'chaotic' to be programmed, that is the behaviour is very sensitive to multiple t=0 parameters.

Did sim full stall training for initial type rating and have done it again every few years. Last year did fully developed a320 spin in the Altheon sim at LGW. I was surprised at the 'classic' spin that developed and how easily it recovered using the standard technique. I think we lost about 7000'. Good to know how much respect has to be given to the rudder on these a/c.

You don't think that this might be just a standard equation spin generated for generic interest .. and of no particular relevance to the A320 ? What validation description was provided by Alteon ?

Spin

Disregarding the fact, that until now i never heard, that reliable flight tested post stall / spin data are available for the Airbus i think you flew in wonderland environment.

Or are you just talking about the altitude loss starting with the recovery, disregarding the altitude loss from upset until start of first recovery inputs?

At what level did the procedure start?

I did spin training in the T37 trainer, altitude needed from entry to recovery to S&L again between 5.000 to 9.000 feet for a fully developed spin.

Pan Am B707-120 / 25Feb59 N709PA suffered in-flight separation of the #4 engine during a training mission north of Paris France. An PAA instructor pilot was demonstrating minimum control speeds at 8000 feet, the B707 stalled at an estimated speed of 120 KIAS and started into a right spin. The plane lost 2000 feet of altitude, before a violent recovery maneuver tore the engine and pod mount from the wing. Aircraft flew to London. Engine recovered in pasture near Pioneis on the Brest Peninsula.

With only 2000 feet of altitude loss, this could not have been a fully developed spin.
Sounds more like a post-stall departure.
Demonstrating Vmca at 8000 feet sounds a bit foolish, but those were the bad old days.
