I did some very interesting test flying many years ago in some light twins. The reason was to explore a "deep stall" ie, after provoking a stall(@ 10,000 feet or so) wait for the nose to drop and then pull in full back stick for one second.
The results were amazing, and suffice to say, enough to gain a very healthy respect for speed control at anywhere close to the ground.
These light twins were generally very docile aircraft, PA-31, EMB110 , B200, and similar. The height loss is these deliberately provoked stalls were universally in excess of 2,500 feet. This, from aircraft that regularly lose no more that 50 to 100 feet in stall training.
I have never stalled a heavy jet at or close to its service ceiling, but I would say it is high time this was included in the standard syllabus.(of course only in the sim). I would have a guess that once "deep stalled" a A330 would require in excess of 15,000 to recover, and only then if the correct control Imputs were done.
Thoughts anyone?
