SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS & CNS AUDIO PANEL AVOIDANCE MANAGEMENT Automatic Flight Control System At 50 feet from the VNAV Target Altitude, the flight director automatically transitions from VNAV Target Altitude Capture to Altitude Hold Mode and tracks the level leg. As Altitude Hold Mode becomes active, the white 'ALT' annunciation moves to the active vertical mode field and flashes green for 10 seconds to indicate the automatic transition. The flight director automatically arms Vertical Path Tracking, allowing upcoming descent legs to be captured and subsequently tracked. Altitude Reference (in this case, equal to VNV Altitude Target)) Figure 7-14 Automatic Mode Transitions During Altitude Capture Changing the VNAV Target Altitude NOTE: Pressing the CWS Button while in VNAV Target Altitude Capture Mode does not cancel the mode. Changing the current VNAV Target Altitude while VNAV Target Altitude Capture Mode is active causes the flight director to revert to Pitch Hold Mode. Vertical Path Tracking and the appropriate altitude capture mode are armed in preparation to capture the new VNAV Target Altitude or the Selected Altitude, depending on which altitude is to be intercepted first. VNAV target altitudes can be changed while editing the active flight plan (see the Flight Management Section for details). Glidepath Mode (GP) (SBAS Only) NOTE: Pressing the CWS Button while Glidepath Mode is active does not cancel the mode. The autopilot guides the aircraft back to the glidepath upon release of the CWS Button. Glidepath Mode is used to track the SBAS-based glidepath. When Glidepath Mode is armed, 'GP' is annunciated in white in the AFCS Status Box. Selecting Glidepath Mode: 1) Ensure a GPS approach 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 FMS is the selected navigation source (use the Active Nav Softkey to cycle through navigation sources). 3) Press the APR Key.
