SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS & CNS AUDIO PANEL AVOIDANCE MANAGEMENT FLIGHT Automatic Flight Control System Vertical Navigation Modes (VPTH, ALTV) Note: VNAV is disabled when parallel track or dead reckoning mode is active. Note: The Selected Altitude takes precedence over any other vertical constraints. Vertical Navigation (VNAV) flight control is available for enroute/terminal cruise and descent operations any time that VNAV flight planning is available. Refer to the Flight Management Section for more information on VNAV flight plans. Conditions for availability include, but are not limited to: • The selected navigation source is FMS. • A VNAV flight plan (with at least one altitude-constrained waypoint) or vertical direct-to is active. • VNAV is enabled. • Crosstrack error is valid and within certain limits. • Desired/actual track are valid or track angle error is within certain limits. • The VNAV Target Altitude of the active waypoint is no more than 250 ft above the current aircraft altitude. The flight director may be armed for VNAV at any time, but no target altitudes are captured during a climb. The Command Bars provide vertical profile guidance based on specified altitudes (entered manually or loaded from the database) at waypoints in the active flight plan or vertical direct-to. The appropriate VNAV flight control modes are sequenced by the flight director to follow the path defined by the vertical profile. Upon reaching the last waypoint in the VNAV flight plan, the flight director transitions to Altitude Hold Mode and cancels any armed VNAV modes. Vertical Path Tracking Mode (VPTH) Note: If another pitch mode key is pressed while Vertical Path Tracking Mode is selected, Vertical Path Tracking Mode reverts to armed. NOTE: Pressing the CWS Button while Vertical Path Tracking Mode is active does not cancel the mode. The autopilot guides the aircraft back to the descent path upon release of the CWS Button. When a vertical profile (VNAV flight plan) is active and the VNV Key is pressed, Vertical Path Tracking Mode is armed in preparation for descent path capture. 'VPTH' (or '/V' when Glidepath or Glideslope Mode is concurrently armed) is annunciated in white in addition to previously armed modes. If applicable, the appropriate altitude capture mode is armed for capture of the next VNAV Target Altitude (ALTV) or the Selected Altitude (ALTS), whichever is greater.
