GLIDEPATH MODE (GP) (WITH EXTERNAL WAAS ENABLED
IFR NAVIGATOR ONLY)
Glidepath Mode is used to track a WAAS or other satellite-based augmentation
system SBAS generated glidepath. When Glidepath Mode is armed, 'GP' is annunciated
in white in the Autopilot Status Box.
Selecting Glidepath Mode:
1) EXTERNAL NAVIGATOR: Ensure a GPS approach with vertical guidance
(LPV, LNAV/VNAV, LNAV +V) is loaded into the active flight plan. The active
waypoint must be part of the flight plan (cannot be a direct-to a waypoint
not in the flight plan).
2) Ensure that GPS is the selected navigation source.
3) Press the APR Key (GMC 305) or touch the autopilot, then touch APPR
(only available when an external GPS navigation source (i.e., GTN or GNS
Series) is configured).
