@gums:
In my mind, PJ2 has always been one of the staunchest and unswerving advocates of attitude & power, flight path stabilization, and 'knowing' your aircraft, both aero & systems-wise.
It appears to me that he is only explaining how the system works & what they were dealing with. But I don't want to speak for someone else.
@ The stall:
I flew 3 T-tail air transport aircraft which did not 'deep stall' and one military conventional tail aircraft that did.
The bottom line on this recovery and associated techniques is that none were ever attempted because there was no recognition that they were ever required.
If the term 'deep stall' is not meaningful enough or does not fit the formal definition, or offensive to anyone, call it a 'pterodactyl' or a 'lemon drop'. That won't change it one bit.
Just don't call me late for dinner.
