AUTOMATIC FLIGHT CONTROL SYSTEM
BASIC AUTOPILOT OPERATION
This section provides an overview for autopilot engagement and disengagement. A more detailed description
follows in Section 7.5.
• Autopilot Engagement — The autopilot may be engaged by pushing the AP Key on the AFCS Control Unit.
Annunciations regarding the engagement are indicated on the PFD.
• 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, ‘PIT’ and ‘ROL’ 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/YD DISC Switch, which is located on the control stick. An autopilot disconnect tone will be heard and
annunciated on the PFD. Other ways to disconnect the autopilot include:
– Pressing the AP Key on the AFCS Control Unit
– Pressing the GA Switch (located on the left throttle) (not applicable with Underspeed Protection option)
– Operating the MEPT Switch (located on each control wheel)
– Pulling the autopilot circuit breaker
In the event of unexpected autopilot behavior, pressing and holding the AP/YD DISC Switch will disconnect
the autopilot and remove all power to the servos.
