i know the use of the trim button on the uh-1 helicopter but i just get confused why i heard that i have to "press the trim release and fly the aircraft to a new altitude and then release, the new altitude will then be held."
how do you fly an aircraft to a higher altitude when you depress your trim release button?(on a uh-1 huey) i thought that the trim release button is used to relieve the force on the cyclic?
