chucks et al,
Tailplane stall.
The extract is from a BAE SYSTEMS safety awareness magazine. Note that the initial icing section applies to both jets and turboprops, but only the turboprops have specific advice for tailplane stall recovery.
This might imply that in theory, all types could be susceptible to tailplane stalling, but in practice, only the turboprops have encountered the problem – and fixes (restrictive flap use) were put in place.
Most jet aircraft have powered (irreversible) controls which negate the problem, but note that the BAE 146 / RJ have manual controls:
– IIRC the Q400 has a powered elevator and thus may not be susceptible to tailplane stalling.
