Operation
AUTOPILOT (A/P) ENGAGE / DISENGAGE BUTTON
When the A/P button is pressed, the Autopilot, FlightDirector (FD) , and Yaw Damper (YD if installed) engage. The annunciator adjacent to the function will illuminate. The system will engage in the ROLL , PITCH , and YAW DAMPER modes. The roll and pitch attitudes will be the attitudes present at the moment the A/P button was pressed. If the A/P button is pressed a second time, the autopilot will disengage leaving the FD and YD functions active. The annunciator adjacent to the A/P button will extinguish and a disengage tone will sound.
YAW DAMPER (YD) BUTTON (IF INSTALLED)
Pressing the YD button will engage the Yaw Damper and illuminate the annunciator adjacent to the YD button. Depressing the YD button a second time will disengage the Yaw Damper and extinguish the adjacent annunciator. The YD normally engages with the autopilot but can be pressed ON or OFF at anytime completely independent of the autopilot. Therefore, it is essential that the YD always be disengaged for takeoff and landing.
FLIGHT DIRECTOR (FD) MODE
The Flight Director is automatically activated and the Steering Bars come into view by pressing the AP button. To use the Flight Director only, press the AP button again canceling AP but leaving FD and YD engaged or engage the FD from the AP READY mode.
HEADING (HDG) MODE
Press the HDG button to engage the Heading Mode. In this mode the system will track the heading bug on the ND . Any heading bug change will cause the aircraft to turn, intercept, and track the new heading. Depressing the HDG button a second time will cancel the mode and default back to ROLL Mode.
NAV MODE
To Intercept and track a VOR signal, first tune the appropriate frequency on the navigation radio, then push NAV.
APPROACH ( APR ) MODE
When pressed, will arm the Approach mode.
BACK COURSE APPROACH ( REV ) MODE
When pressed, will select the back course approach mode.
ALTITUDE HOLD ( ALT ) MODE
When pressed, will displays Altitude Hold mode, allowing you toggle altitude arming on or off. When ALT HOLD is annunciated, the automatic flight control system will capture the altitude displayed.
The autopilot will give a visual alert an aural tone 1000 ft. and 200 ft. before reaching the altitude.
ROTARY KNOB
Used to set the altitude alerter/altitude preselect reference altitude.
VERTICAL SPEED ( VS ) MODE
When pressed bring up the commanded vertical speed in the display. It doesn't capture VS in this version.
VERTICAL SPEED ( UP / DN )
Pressing these buttons will increment the vertical speed if displayed.
IAS MODE
When pressed bring up the IAS in the display. Pressing again will acquire and hold the IAS selected.
IAS ( UP / DN )

Pressing these buttons will increment the IAS, if displayed.
