Question No. 1

What is the position of the elevator in relation to the trimmable horizontal stabilizer of a power assisted aeroplane, which is in trim ?

[ Total Que.:43 ]
The position depends on speed, the position of slats and flaps and the position of the centre of gravity.
The elevator deflection (compared to the stabilizer position)is always zero.
At a forward CG the elevator is deflected upward and at an aft CG the elevator is deflected downward.
The elevator is always deflected slightly downwards in order to have sufficient remaining flare capability.
