Hi Send Clowns,

I understand that a T-Tail would be required as it is more prone to be within the disturbed air from the stalled wing.

When I see these type of questions in various sources of feedback, they all tend to contradict each other.

Would you know what the JAA like as the answer to "which aircraft would be more prone to a super stall"? To which there are "Swept wings" as one answer and "T-Tail" as another.

I have seen feedback questions with both Swept Wings and T-Tail in the same answer so that would be the logical one, but if they are listed individually?

Are they asking in terms of the pitch up moment needs to be present (swept wings) or plainly that a T-Tail aircraft is more prone to have lack of pitch moment when its swept wings stall with their nose up tendancy (BAC1-11 for instance)? Ie, as you said a Dash 8 with straight wings would pitch down and thus one would hopefully not get to the "super stall" stage.

Best wishes,

Charlie Zulu.
