I much admired Hazlenut's description of stalls. With nearly all training now being done on simulators few airline pilots ever experience genuine stalls, or even the approach to the stall on the types for which they are qualified. I am now retired but used to be a training captain on VC10s (T-tailed), 707s and 747s, and did C of A test flights on all 3 types.
The stalls both in training and on C of A flights were always, wings level, slow deceleration (1kt/sec) to the 1G stall (or stick push in the case of the VC10). I have no experience of stalls in banked flight, or accelerated stalls when pulling G. The aerodynamic buffet in all cases was distinct from the turbulence felt in clear air near jet streams and from the turbulence in the vicinity of thunderstorms.
The 747 was an interesting case since the stall speed clean was defined by the maximum acceptable buffet, D P Davies describes it as a violent vertical bounce, sometimes with a lateral component. To the best of my knowledge the 747 has not been stalled in the clean configuration. In each of the flaps down configurations the stalls were immaculate with good natural buffet, good controllability and a good margin between the buffet and the 1G break, followed by a classic nose drop.
The VC10, being a T-tail aircraft, required a stick shaker and stick pusher, and on C of A flights was always fitted with an incidence meter above the coaming. If the stick push had not occurred before 14deg incidence you pushed like mad!
I relate all this because of the discussion in previous posts about whether the pilots could have distinguished between pre stall buffet and the turbulence associated with thunderstorms. I think the answer is in most cases 'yes', the two are distinguishable. However, in heavy turbulence it is highly probable that the pre stall buffet would be 'lost' in the general ambient turbulence. And in really heavy turbulence one's brains feel rather 'scrambled' which would make it even more difficult! In which case it is quite possible that the pilots on AF447 would not have been able to discern the pre stall buffet.
