Is trim linear with speed?
Question in my head that came from the A320 stall thread....
In general is trim change linear with speed change?
And more specifically; is it linear with FBW aircraft - A320?
My thoughts would be that according to the lift formula you’d would require proportionally more nose up trim for every knot of speed loss.
It has to be correlated but if it’s not linear what is it?
Thanks in advance.
