The trim tab at the elevator is deflected upwards. In which position is the corresponding indicator?
Refer to figure.
When the elevator trim is moved up, it will force the elevator to move down and thus decrease the down force from the stabilizer. This will cause a nose down moment from the wing lift, so the cockpit trim indicator should show nose down.
A good way to remember is to think that Trim tab and trim indicator are opposite, therefore:
- Elevator trim tab up – trim indicator gives nose down
- Elevator trim tab down – trim indicator gives nose up
