Autopilot system
The autopilot system is integrated into / with the EFIS unit.
Please refer to the latest revisions of the MGL iEFIS Panel Operator Manual
and MGL Integrated Autopilot User and Installation Manual for detailed
instructions on autopilot operation and functionality.
The EFIS / autopilot inputs data from an electronic compass and AHRS, and
controls two servos (one for pitch and one for roll) linked to the aircraft
control system.
Power to the servos is controlled via a switch labeled AUTOPILOT, located
on the instrument panel (refer to paragraph 7.17.2). This switch must be
on for the autopilot / EFIS outputs to have any effect on aircraft attitude.
The autopilot can be engaged in several ways:
The autopilot engage / disengage button on the control stick(s) (refer
to paragraph 7.2).
Via the EFIS keypad.
The autopilot can be disengaged in several ways:
•
The autopilot engage / disengage button on the control stick(s) (refer
to paragraph 7.2).
•
Via the EFIS keypad.
•
A servo reports (to the autopilot / EFIS) a slipping clutch or torque
overdrive for 1 second, i.e. the pilot overrides the autopilot via
mechanical force on the control stick.
•
Removing power to the autopilot servos (switching off the
AUTOPILOT switch), effectively removing the EFIS / autopilot’s
control / actuation of the servo motors. Refer to paragraph 7.17.2.
