The system B tail-plane trim lever can be used to control the elevator trim setting. The lever is spring-loaded to the centre position. Click-and-drag the lever forwards for nose-down trim and rearwards for nose-up trim. The amount of trim change per second depends on how far the lever is moved fore or aft, and the tail-plane position can be monitored on the tail-plane indicator gauge.

The trim lever will also move in response to any keyboard or joystick trim assignments.
