AUTOMATIC FLIGHT CONTROL SYSTEM
Upon reaching the glidepath, the flight director transitions to Glidepath Mode and begins to capture and
track the glidepath.
Once the following conditions have been met, the glidepath can be captured:
• A GPS approach with vertical guidance (LPV, LNAV/VNAV, LNAV+V) is loaded into the active flight plan.
• The active waypoint is at or after the final approach fix (FAF).
• Vertical deviation is valid.
• The CDI is at less than full-scale deviation
• Automatic sequencing of waypoints has not been suspended (no 'SUSP' annunciation on the HSI)
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.
GLIDESLOPE MODE (GS)
Glideslope Mode is available for LOC/ILS approaches to capture and track the glideslope. When Glideslope
Mode is armed (annunciated as 'GS' in white), LOC Approach Mode is armed as the lateral flight director
mode.
