Section 4 - Normal Procedures
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

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

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.

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.
