SR22 Airplane Description

Yaw Trim System

Yaw trim is provided by spring cartridge attached to the rudder pedal
torque tube and console structure. The spring cartridge provides a
centering force regardless of the direction of rudder deflection. The
yaw trim is ground adjustable only.
On airplanes with electric rudder (yaw) trim, trim changes are pilot
controlled through a linear actuator connected to a hinged trim tab on
the rudder trailing edge. The actuator is installed in the rudder. A
RUDDER TRIM indicator with integral rocker switch is mounted in the
console immediately adjacent to the FLAP control switch. Pressing the
left half of the switch initiates Nose L trim and pressing the right half
initiates Nose R trim. A needle sweeps the trim indicator scale to
indicate trim position. The full Nose Right trim tic is labeled TAKEOFF.
Rudder (yaw) trim operates on 28 VDC supplied through the 2-amp
PITCH / YAW TRIM circuit breaker on Main Bus 1. The switch and
indicator are not internally illuminated.
