Hi,
May I ask some basic questions about this subject?
I am not enrolled on a flight school anymore at the moment so I think a new post on this forum is the best way to find out.
First question is about ailerons and roll spoilers:
If you give a certain roll input on the yoke, do you always get a certain amount of spoiler and aileron deflection, regardless of speed or altitude?
The books say that ailerons are not useful at high mach numbers, and because of wing twisting e. a. But do ailerons still work at these speeds in the same way as on low speeds?
Second question is related to the first: It is well known that yaw dampers are used to avoid dutch roll, but do they also give turn coordination?
Because as far as I know, the rudder of a jet is not used in normal flight with the gear up, in normal cases. Is it perhaps because roll spoilers also give a yawing moment?
I hope this is not too confusing and look forward to your replies! Thanks
