Trim Control
The GSA 28 autopilot servos can be used to control the trim system in an aircraft.
When the autopilot is disengaged, the servos can adjust the trim speed based on the
current aircraft airspeed. This allows the trim to run slower at high airspeeds and
faster at low airspeeds. When the autopilot is engaged in the air, the servos can adjust
the trim control to minimize the force on the primary controls. This helps ensure the
aircraft will be properly trimmed when the autopilot is later disengaged.
During the flight test phase, the trim system is configured and set up after the
primary autopilot performance has been properly configured. This is done so the
pilot can focus on properly adjusting the performance of the primary autopilot system
without having the autotrim functionality interfere.
NOTE: Ensure basic autopilot functionality is properly adjusted before enabling
trim control for any servo.
