VERTICAL PATH TRACKING MODE (VPTH)
If another vertical mode key is pressed while Vertical Path Tracking Mode is selected, Vertical Path
NOTE:
Tracking Mode reverts to armed.
Pressing the CWS Button while Vertical Path Tracking Mode is active does not cancel the mode. The
NOTE:
autopilot guides the aircraft back to the descent path upon release of the CWS Button.
When a vertical profile (VNV 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 VNV Target Altitude (ALTV) or the Selected
Altitude (ALTS), whichever is greater.
Prior to descent path interception, the Selected Altitude must be set below the current aircraft altitude
by at least 75 feet. For the flight director to transition from Altitude Hold to Vertical Path Tracking Mode,
acknowledgment is required within five minutes of descent path interception by:
• Pressing the VNV Key
If acknowledgment is not received within one minute of descent path interception, the white 'VPTH'
annunciation and the VNV Key annunciator light start to flash. Flashing continues until acknowledged or the
descent path is intercepted. If the descent is not confirmed by the time of interception, Vertical Path Tracking
Mode remains armed and the descent is not captured.
