GS (Glideslope) Mode
The autopilot glideslope function will capture and track an ILS glideslope.
The following conditions must be met for at least 1 second to automatically
arm the GS mode:
1. The appropriate NAV receiver must be tuned to the appropriate ILS
frequency.
2. The ILS signal must be valid – no NAV or GS failure annunciations shown
on the PFD.
3. The CDI must be set to LOC 1 or LOC 2 as appropriate.
4. The autopilot must be in NAV/APR/ALT modes.
5. The aircraft must be within 50% CDI needle deection of the Localizer
centerline.
6. The aircraft must be more than 10% below center on the glideslope
indicator.
If it is necessary to disable the glideslope mode after it has been
automatically armed, press the APR mode button on the autopilot computer.
The GS annunciation will ash to acknowledge this. To then re-arm the
glideslope mode, press the APR mode button on the autopilot computer
again. The GS annunciation will immediately extinguish, and then reappear
after one second if all of the above conditions (1-5) are still met.
With the glideslope mode armed, once the aircraft arrives at 5% below center
on the glideslope indicator, the ALT annunciation will disappear to indicate
engagement of the glideslope mode.
To manually engage the GS mode the following conditions must be met:
1. The appropriate NAV receiver must be tuned to the appropriate ILS
frequency.
2. The ILS signal must be valid – no NAV or GS failure annunciations shown
on the PFD.
3. The CDI must be set to LOC 1 or LOC 2 as appropriate.
4. The autopilot must be in NAV/APR/ALT modes.
5. Ensure the aircraft is not greater than 10% above the glideslope
centerline.
6. Press the ALT button on the autopilot computer.
The GS annunciation will ash whenever the glideslope indicator needle
deection exceeds 50%, or a glideslope failure occurs. Whenever a
glideslope failure occurs the FAIL annunciation will also be displayed.
CAUTION: Manual engagement of the glideslope mode when the
aircraft is positioned above the GS centerline will cause a more aggressive
intercept toward the glideslope. Do not manually engage the glideslope
mode if the glideslope needle deection is greater than 10% above center.
