GLIDEPATH MODE (GP)
Pressing the CWS Button while Glidepath Mode is active does not cancel the mode. The autopilot
NOTE:
guides the aircraft back to the glidepath upon release of the CWS Button.
Glidepath Mode is available only in installations with GIA 63W Integrated Avionics Units and when
NOTE:
WAAS is available.
Upon reaching the glidepath, the flight director transitions to Glidepath Mode and begins to capture and
track the glidepath. Glidepath mode is used to track the WAAS-based glidepath. Arming Glidepath Mode
(annunciated in white as 'GP') requires:
• Approach supporting WAAS vertical guidance is loaded into the flight plan
• Expected availability of vertical guidance
• GPS Approach Mode is selected (GPS is the selected navigation source and the APR Key is pressed; see GPS
Approach Mode)
Glidepath capture is inhibited unless all of the following are true:
• The final approach fix (FAF) is the active waypoint
• The CDI is at less than full scale deviation
• Automatic sequencing of waypoints has not been suspended (by pressing the SUSP Softkey)
