autopilot disconnects from the ACL mode, the AFCS
OUT indicator (on the discrete indicator) lights for 20
seconds, and then goes out.
If the pilot is monitoring glide path errors from
the data link on the VGI cross pointers and a display
of a TILT or WAVEOFF discrete signal appears, the
cross pointers will drive out of view. There is no
effect on the cross pointers, from these discretes, if
the monitor link is being used. If the monitor link is
being used for glide-path error display and the
received RF signal is lost, the cross pointers are
driven to a fly-up, fly-right indication. This will alert
the pilot to take corrective action. If the monitor link
is turned off or if primary power is lost, the cross
pointers are driven out of view. When the radar
beacon is being interrogated and is transmitting a
replay in the ACLS mode, the BCN ON lamp (on the
discrete indicator) lights, informing the pilot that the
beacon is operating.
When power to the VGI is
removed or interrupted, a warning flag is immediately
displayed on the indicator. All of these functions
guard against any system malfunctions that may
endanger the pilot or the aircraft.
