In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. The critical angle...

Some reports have described this as a deep stall, but this was a steady state conventional stall. A deep stall is associated with an aircraft with a T-tail...

production was augmented pitch control to avoid deep stall conditions at high angles of attack. The stall issue had been raised during development but had...

primary stall at most forward center of gravity was sufficient to trim a deep stall at the aft center of gravity, but recovery from deep stall was immediate...
