Refer to Section 7 – Systems Description for a description of the
autopilot and altitude selector and their respective modes.
The Autopilot is integrated with the Altitude Selector/Alerter and can
be operated with or without data inputs from the Altitude Selector/
Alerter. The autopilot ALT and VS modes are coupled to the Altitude
Selector/Alerter ALT and VS outputs by pressing and holding the
Autopilot Programmer/Computer VS button and then pressing the ALT
button. Altitude Selector Vertical Speed output can be individually
coupled to the autopilot through the autopilot VS mode by pressing the
autopilot VS button.
• WARNING •
The pilot must properly monitor and control the engine power
to avoid stalling the airplane in autopilot altitude hold or
vertical speed modes.
• Note •
Any coupled Altitude Selector / Alerter mode can be disabled
by disconnecting the autopilot.
Autopilot and Altitude Selector Pre-Flight Tests
1. Battery Master Switch ............................................................... ON
2. Transponder .............................................................................. ON
3. Avionics Power Switch .............................................................. ON
Note that all autopilot annunciators, except CWS, and TRIM
illuminate. After about 5 seconds, all lights will go out. When the
turn coordinator gyro has reached operational RPM, the RDY
annunciator will come on.
4. Altitude Selector Tests:
a. Altimeter ................................................... Set Field Elevation.
b. Self-Test – On power up, all annunciators come on for
approximately 5 seconds and then sounds an audio tone.
After the self-test is complete, press the DTA and then BAR
buttons on the altitude selector.

c. Rotate altitude selector input knob to set BARO to the nearest
0.1 inch Hg.
d. Push ALT button to display ALT SEL. With a flashing SEL
annunciator, rotate the selector knob to input an altitude 300
to 400 feet lower or higher than the indicated altitude.
e. Push the VS button. Rotate the selector input knob to input the
desired climb (+) or descent (-) vertical speed.
f. Push ALT button, ALT SEL annunciator will illuminate.
g. Engage autopilot HDG mode.
h. Press and hold the VS button and then press the ALT button.
Autopilot VS and ALT annunciators will illuminate.
i. Rotate altitude selector knob to change selected altitude to
match field elevation. VS annunciator on autopilot
programmer should go out when the ALT SEL setting on the
altitude selector is within 100 feet of indicated altitude on
altimeter. Autopilot ALT mode should remain illuminated,
indicating autopilot altitude hold is engaged. If ALT
engagement does not occur within 100 feet of indicated
altitude, readjust BARO setting on altitude selector.
5. Autopilot Tests
a. Heading Mode .................................................................TEST
1.) Center the HDG bug under the lubber line on the HSI.
2.) Momentarily press HDG button on autopilot Mode
Selector. Note that HDG light illuminates.
3.) Then rotate HDG knob on the HSI to the left then right.
Note that control yokes follow movement of knob. Then
return HDG bug to lubber line.
b. Vertical Speed .................................................................TEST
1.) Press VS button on autopilot programmer/computer. Note
that VS light illuminates VS+0.
2.) Rotate the VS control knob to 500 FPM up (+5). After a
short delay, the control yoke will move aft.
3.) Rotate the VS control knob to 500 FPM down (-5). After a
short delay, the control yoke will move forward.

c. Altitude Hold ....................................................................TEST
1.) Depress ALT button on autopilot programmer/computer.
Note that ALT annunciator comes on, VS annunciator
goes out, and yoke does not move.
d. Overpower Test:
1.) Grasp control yoke and input left aileron, right aileron,
nose up, and nose down to overpower autopilot.
Overpower action should be smooth in each direction with
no noise or jerky feel.
e. Radio Check:
1.) Turn on NAV1 radio, with a valid NAV signal, and select
VLOC for display on the HSI.
2.) Use autopilot programmer/computer to engage NAV
mode and move OBS so that VOR deviation needle
moves left or right. Note that control yokes follow direction
of needle movement.
