PILOT'S OPERATING HANDBOOK
SUPPLEMENT
CESSNA 400B AUTOPILOT
(TYPE AF-550A)
sory unit, will illuminate yellow when the autopilot is disengaged by any
means other than the control wheel AUTOPILOT DISENGAGE switch.
Whenever the autopilot is disengaged by any means, the autopilot disen-
gage horn will produce a short tone lasting 1 to 2 seconds with decreasing
amplitude.
The autopilot disconnect warning (WARN) light (yellow) will
remain on, until it is cancelled by pressing the control wheel AUTOPILOT
DISENGAGE switch.
The back course (REV SNS LOC 1/LOC 2) selector switch, mounted in
.
the autopilot accessory unit, is only used when conducting localizer
approaches.
With the navigation receiver set to a localizer frequency
,
positioning the switch to LOC 1 or LOC 2 (back course) will reverse the
appropriate signals to provide for back course operation for either
autopilot or manual flight. Except when a horizontal situation indicator is
installed,
selecting back course (REV SNS LOC 1/LOC 2) causes reversal
of the Course Deviation Indicator (CDI) indication, whether or not the
autopilot is being used.
The navigation receiver selector switch (AP NAV 1/NAV 2), installed
in the autopilot accessory unit when dual navigation receivers are
installed, allows the autopilot to operate in conjunction with either
navigation receiver.
