Feature Article: Trim instruction
The direction to move the trim and the proper instructional
words to use are a common source of confusion. Raising the trim
wheel lowers the nose. It is better to have the student think
of touching the trim wheel as touching the tail of the aircraft.
Moving the trim wheel up will cause air flow over (under) the
elevator to move the tail up. Thus, raising the trim wheel raises
the tail while lowering the nose. Lowering the trim wheel lowers
the tail and raises the nose. By agreement, I make a practice
of telling the student the direction to move the trim wheel. I
also advise against pinching or flipping the wheel. I suggest
use of the index finger on the knobs of the wheel. A full turn
and count system seems to have been deliberately engineered by
Cessna. All full movements of the trim should be with the forefinger
getting the very top or bottom button of the trim wheel and moving
it as far as possible. Always start at the very top button or
the very bottom button with the finger tip. Grasping the trim
wheel between the fingers prevents the full movement needed thus
making necessary more trim adjustment. Pinching the wheel always
leaves the turn one button short.
