Infreq:
Having read the article "Can airliners recover from a stall" I was astonished to read this extract, also from the same poster who has clearly been there, done it and got a cupboard full of tee shirts:

"Normal 'full back stick' stall testing is done with idle thrust, and stabiliser trim trimmed for Vs+10, and a controlled deceleration at 1Kt/sec until stall occurs. 747FOCAL's and my definition of a 'wind up' stall may differ, but for deliberate efforts to enter the deep stall, large UP stabiliser trim was used with large thrust settings to gain high pitch attitudes just pre-stall, and then chopping the thrust and rapidly applying full UP elevator. Disneyland offers no more exciting ride."
The actions described in the last sentence to induce a deep stall seem to be taken close to verbatim from the recent BEA report. Frightening
