In the late 80s, early 90s, I carried out a number of post major inspection air tests in the RAF's VC10s.

In most configurations she stalled like any aeroplane, with aerodynamic as well as stick shake to announce the on coming stall, wings level and don't touch the rudders and at the stall the nose dropped away and standard recovery unload, apply power and recover. How anyone could not recognise what was about to happen is beyond me - it required strength and determination to get there!

However, the 10 had a 'stick pusher' fitted to prevent a true deep stall (the reason why this was fitted only to T tail aircraft on the British register is a long story). The pusher speed was calculated and you used a lot of muscle power to keep the IAS coming back to that figure. In addition an AoA indicator was temporarily installed on top of the coaming in front of the captain and if you got to the magic figure (+14 degrees seems to ring a bell) before the push you got out of it quickly by unloading etc. Try again and if still no push then the system was u/s and needed recalibration.

Contrary to some comments above, the flight simulator did a good job (and still does) of reflecting the whole stall and recovery process - not absolutely the same but good enough to train before the air test.
