AUTOMATIC FLIGHT CONTROL SYSTEM
7.4 AUTOPILOT OPERATION
NOTE: Refer to the POH for specific instructions regarding emergency procedures.
The autopilotoperates flight control surface servos to provide automatic flight control. Pitch and rollcommands are provided to the servos, based on the active flight director modes. The autopilot uses pitch and roll rates to stabilize the aircraft attitude during upsets and flight director maneuvers. Flight director commands are rateand attitude-limited, combined with pitch and roll damper control, and sent to the pitch and roll servo motors.
Pitch autotrim provides trim commands to the pitch trim servo to relieve any sustained effort required by the pitch servo. The pitch servo measures the output effort (torque) and provides this signal to the pitch trim servo. The pitch trim servo commands the motor to reduce the average pitch servo effort.
When the autopilot is not engaged, the pitch trim servo may be used to provide manual electric trim (MET). This allows the aircraft to be trimmed using a control wheel switch rather than the trim wheel. Manual trim commands are generated only when both halves of the MET Switch are operated simultaneously. Trim speeds are scheduled with airspeed to provide more consistent response.
Servo motor control limits the maximum servo speed and torque. The servo mounts are equipped with slipclutches set to certain values. This allows the servos to be overridden in case of an emergency.
ENGAGING THE AUTOPILOT
NOTE: Autopilot engagement/disengagement is not equivalent to servo engagement/disengagement. Use the CWS Button to disengage the pitch and roll servos while the autopilot remains active.
WhentheAPKeyispressed,theautopilotandflightdirector(ifnotalreadyengaged)areactivated. Engagement is indicated by a green ‘AP’ annunciation in the center of the AFCS Status Box. The flight director engages in Pitch and Roll Hold modes when initially activated.

AUTOMATIC FLIGHT CONTROL SYSTEM
CONTROL WHEEL STEERING
During autopilot operation, the aircraft may be hand-flown without disengaging the autopilot. Pressing and holding the CWS Button disengages the pitch and roll servos from the flight control surfaces and allows the aircraft to be hand-flown. At the same time, the flight director is synchronized to the aircraft attitude during the maneuver. The ‘AP’ annunciation is temporarily replaced by ‘CWS’ in white for the duration of CWS maneuvers.
In most scenarios, releasing the CWS Button reengages the autopilot with a new reference. Refer to the flight director modes section for specific CWS behavior in each mode.
Control Wheel Steering
Figure 7-27 CWS Annunciation
DISENGAGING THE AUTOPILOT
The autopilot is manually disengaged by pushing the AP DISC Switch, GA Switch, MET ARM Switch, or the AP Key on the MFD. Manual disengagement is indicated by a five-second flashing yellow ‘AP’ annunciation and a three-second autopilot disconnect aural alert. After manual disengagement, the autopilot disconnect aural alert may be cancelled by pushing the MET ARM or AP DISC Switch (AP DISC Switch also cancels the flashing ‘AP’ annunciation).
Figure 7-28 Manual Autopilot Disengagement
Automatic autopilot disengagement is indicated by a flashing red ‘AP’ annunciation and by the autopilot disconnect aural alert, which continue until acknowledged by pushing the AP DISC or MET ARM Switch. Automatic disengagement occurs due to:
• System failure |
• Invalid sensor data |
• Inability to compute default flight director modes |
• Stall warning |
(FD also disengages automatically) |
