Clandestino,
Only in the tales of yesteryear, when swept wing was largely an unknown quantity. Since then, wise aerodynamicists came up with something called "washout". When measuredly applied, it assures that roots stall first, thereby: 1)eliminating pitch-up associated with tips that stall first 2) reducing rolling momentum from asymmetric flow separation - separation now occurs closer to CG in lateral sense 3) keeping the outboard ailerons effective.
Not quite. Even if the entire length of a wing, swept or straight, stalls at the same time the separation of the airflow occurs towards the rear of the wing causing the centre of lift to move forward. Unchecked that may cause pitch up.
Please provide reference to this statement of yours.
I can't, I have paper copies of several flight test documents on controls and stability.
Nowadays, on swept wing transports, washout reduces the effect to the point of elimination, as was tragically proven by certain crew of certain airliner that fell flatly into Atlantic without gyrations that have to be expected with tips stalling first
Did you not spot the part about several roll excursions, some up to 40 odd degrees and the 270 heading change?!
It is not the tendancy of a T-Tail to deep stall it is the recovery that can be a problem. Note that the King Air, although a T-Tail, is not prone to deep stalls, straight wing you see!
