Heading Hold Function until the CDI Indicator is
less than 50% deflected, at which time the
system will automatically convert to APR mode.
If a valid localizer signal is not being received from the NAV 1 radio, the display will flash,
and Approach Hold will not function.

• Landing.
•
NAV 1 is no longer receiving the localizer signal.
•
APR mode is switch OFF, or to another Course Mode .
•
AP Master is switched OFF.
Reverse (Backcourse) Function
Depress this key to toggle the Reverse Hold mode on/off. When the system is engaged,
the key will illuminate. This function requires a valid localizer backcourse signal from the
NAV 1 radio in order to operate.

localizer signal.
1.3.1.4 ROLL AXIS FAILURE
Failure Annunciators
When illuminated, indicates failure of the roll axis and will disengage the
autopilot. Illuminates whenever the continuous monitoring system detects a roll
axis fault, or is not receiving information from the gyro compass..
The AP Servo Annunciator will annunciate a fault, indicating that the AP Servos
are temporarily disengaged.
The ARM indicator for the roll axis will also flash red whenever a fault condition
exists. The mode indicator (i.e. HDG, NAV, APR) will also flash. This annunciates
to the pilot that the autopilot will not capture the heading, or NAV radial track.
