Thanks for your answers:
For 4 & 5:
Flight Control Laws | Direct Law - Description
For direct law, it is a direct link and for alternate law check this:
Flight Control Laws | Alternate Law - Description
For the ailerons, it is also a direct link with the side-sticks.
1) Do you agree? So it is still electrical but with pitch proportional to the stick?
2) But if we are in alternate law because we have lost Autotrim, will it be a direct connection or will it still be an electrical connection but with pitch (directly controling AoA)
Thanks...
