moving the switch aft will initiate nose-up trim. Neutral (takeoff) trim is
indicated by the alignment of a reference mark on the yoke tube with a tab

primary pitch control system not involving a jammed elevator.
Elevator (pitch) trim operates on 28 VDC supplied through the 2-amp
PITCH TRIM circuit breaker on ESS BUS 2.
