16. BACK-COURSE LIGHT (BC) (Installed
in
a remote position, as shown, with 300A,
400A and 400B autopilots only.) - The remote amber BC light will illuminate
when back-course operation is selected by the REV SNS LOC 1 switch (17)
mounted on the left-hand instrument panel or the BC function of 300A autopilot.
CAUTION
When back-course operation is selected, the course (omni) devia-
tion bar (15) on the HSI does not reverse. However, selection of back-
course operation will always cause the localizer signal to the
autopilot
to reverse for back-course operation.
17. BACK COURSE REVERSE SENSE (REV SNS) LOC 1 OR LOC 2 SELECTOR
SWITCH - With AP switch ON (on 400A or 400B Autopilot control units) and
either LOC 1 or LOC 2 selected, localizer signals to the Cessna 400A or 400B
Autopilots will reverse for back-course operation. With autopilot ON or OFF, the
course (omni) deviation bar on the HSI will not reverse but the standard CDI
pointer will reverse depending on the position of the REV SNS switch.
18. AUTOPILOT (A/P) NAV 1 OR NAV 2 SELECTOR SWITCH - (Installed with
400A and 400B Autopilots only) Selects appropriate signals from the desired
navigation receiver to be coupled to the autopilot.
