Autopilot Engagement — The autopilot may be engaged by pushing the AP Key on the GMC 605 Mode
Control Panel. A green LED will illuminate indicating the autopilot is engaged in the active modes as
shown on the display.
Autopilot Engagement with Flight Director Off — Upon engagement, the autopilot will be set to hold the
current attitude of the airplane, if the flight director was not previously on. In this case, 'ROL' and 'PIT' will
be annunciated.
Autopilot Engagement with Flight Director On — If the flight director is on, the autopilot will smoothly
pitch and roll the airplane to capture the FD command bars. The prior flight director modes remain
unchanged.
Autopilot Disengagement — The most common way to disconnect the autopilot is to press and release
the AP DISC / TRIM INT Switch
annunciated on the GMC 605/GI 285. Other ways to disconnect the autopilot include:
– Pressing the AP Key on the GMC 605 Mode Controller
– Operating either side of the Electric Pitch Trim Switch (located on the control wheel)
– Pulling the AUTOPILOT circuit breaker
In the event of unexpected autopilot behavior, press and hold the AP DISC / TRIM INT switch to
disconnect the autopilot and remove all power to the servos.
