Integrated Autopilot Upon reaching the glidepath, the autopilot transitions to Glidepath Mode and begins to capture and track the glidepath. System Overview Flight Instruments EIS CNS Interface GPS Navigation Flight Planning Hazard Avoidance Glidepath Mode Armed Once the following conditions have been met, the glidepath can be captured: • 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. If Glidepath Mode is active and any of the following occurs, the Integrated Autopilot reverts to Pitch Hold Mode: • The active navigation source is manually or automatically switched. • WAAS glidepath data from the external GPS navigator fails or becomes invalid. GLIDESLOPE MODE (GS) NOTE: Pressing the CWS Button (if equipped) while Glideslope Mode is active does not cancel the mode. The autopilot guides the aircraft back to the glideslope upon release of the CWS Button. NOTE: The integrated autopilot will not capture a glidepath or glideslope from above. Glideslope Mode is available only in installations with a navigation receiver configured. Glideslope Mode is available for LOC/ILS approaches with lateral and vertical guidance to capture and track the glideslope. When Glideslope Mode is armed (annunciated as 'GS' in white), LOC Mode is armed as the lateral autopilot mode. Selecting Glideslope Mode: 1) EXTERNAL NAVIGATOR: Tune and activate the desired localizer frequency. 2) EXTERNAL NAVIGATOR: Ensure that LOC is the selected navigation source (use the CDI SRC Softkey to cycle through external navigation sources if necessary). 190-01115-00 Rev.
