The four modes are as follows:

Mode

Use

Stabilizer (ST)

Used to hold wings level, or to perform manually-commanded left or right turns 
by rotating the L/R TURN knob

Heading (HD)

Used to fly along a heading as selected by the heading bug on the directional 
gyro. Since the autopilot is rate-based, it is possible to move the heading bug 
to a new heading while the autopilot is engaged; the autopilot will command a 
standard-rate turn to the new heading.

Low-sensitivity 
course track
(LO TRK)

Used to fly along a navigation course selected by one of the NAV radio CDIs. 
Use the AP NAV SELECT switch to select the NAV1 or NAV2 CDI for tracking. 
Low sensitivity means the autopilot will ignore short term needle excursions 
due to radio interference or VOR station passage. Maneuver the aircraft to a 
heading within ±10º of the selected course with the CDI no more than one dot 
deflected from center before engaging the autopilot in this mode.

High-sensitivity 
course track
(HI TRK)

Also used to fly along a navigation course selected by one of the NAV radio 
CDIs. High sensitivity means the autopilot will track with maximum authority 
making this mode ideal for VOR or Localizer approaches but less so for VOR 
tracking since the autopilot will track all needle excursions and may behave 
badly during VOR station passage. Maneuver the aircraft to a heading within 
±10º of the selected course with the CDI no more than one dot deflected from 
center before engaging the autopilot in this mode.

Disengaging the Autopilot

The autopilot can be disengaged normally by any of the following three actions:

• Pressing the red AP DISC switch on the yoke

• Pressing and holding for three seconds the AP MODE SEL switch on the yoke

• Pressing and holding for three seconds the L/R TURN knob on the autopilot 

bezel

The RDY light will flash rapidly for five seconds to indicate that the autopilot has disengaged. 
In addition, a beeping audio alert issues while the RDY light flashes to call further attention to 
the disengagement. However, in flight with a noise-canceling headset, the audio alert may 
not be loud enough to be audible.

Using the AP MASTER switch to remove power from the autopilot will also disengage the roll 
servo, but this should be considered only as an emergency procedure should the three 
normal methods fail to disengage the autopilot.

Again, be sure to turn AP MASTER switch OFF before engine shutdown; the autopilot power 
is not removed when the avionics master switch is turned off. It’s a good idea to add this as a 
separate item on the shutdown checklist.
