On the subject of T-tail stalls. A stall situation in a T tail is neither more nor less critical than that of any other configuration, providing it is recognised at the onset and recovery is effected promptly and correctly. The real problem occurs when the stall is allowed to develop into a deep stall, from which many aircraft have been lost.
Two notable examples being a BA Trident over Staines UK in the 60's where the PF retracted the leading edge 'droop' devices too soon leading to aerodynamic deep stall at a fairly low altitude, and a Northwest 727 on a ferry flight, where the young crew were mislead into the stall after pitot tubes became iced and subsequently blocked, the crew became aware of high airspeed in the climb, which they attributed to having a light aircraft. They pulled her back and let her climb, even mistaking the onset of the stall buffet as Mach buffet. As in the first incidence, the entered the deep stall and were unable to effect recovery.
The vast majority of my experience has been with T tails, 1-11's which were a pleasure to fly, as was the 727. THere have been many things put in print about tyhe pros and cons of the aerodynamics of the design, If I don't forget, i will come back to this thread and add some links later on.
