NOTE: GS arming will occur when the above conditions have existed
for 10 seconds. Illumination of the GS annunciator will occur,
indicating arming has been accomplished. The ALT annunciator
remains on. GS capture is indicated by extinguishing of the ALT
annunciation at GS intercept.
4.2.2.4 Manual Arm/Automatic Capture
If approach vectoring locates the aircraft above or too near the GS
centerline at the intercept point, usually the outer marker, it becomes
necessary to execute a manual arming of the GS. This is done by:
1. Pressing the ALT switch once if operating in the altitude hold
mode.
2. Pressing the ALT switch twice if operating in the VS mode. Once
capture is achieved, the GS annunciation will illuminate, and the
ALT annunciation will extinguish.
NOTE: If it becomes necessary to establish a holding pattern at the
outer marker, automatic glideslope arming can be disabled by
pressing the NAV switch a second time while in the NAV/APR mode.
The GS annunciator will flash, and the Disable (DSBL) annunciator
will illuminate, to indicate that the GS mode is disabled. To
reestablish GS arming, press the NAV mode switch again. The
DSBL condition annunciator will extinguish, the GS annunciator will
cease to flash.
