FLIGHT CONTROL
6-12
When a descent leg is captured (Figure 6-12), Vertical
Path Tracking becomes active and tracks the descent
profile. An altitude capture mode (‘ALTS’ or ‘ALTV’) is
armed as appropriate.

Automatic Pitch Hold Reversion
Several situations can occur while Vertical Path
Tracking Mode is active which cause the flight director to
revert to Pitch Hold Mode. Vertical Path Tracking and the
appropriate altitude capture modes are armed for possible
descent profile recapture if the vertical deviation:
• Exceeds 200 ft during an overspeed condition
• Experiences a discontinuity exceeding 200 ft due to
a flight plan change
• Becomes invalid due to excessive cross-track error,
track angle error
• Cannot be computed for a leg type (such as a hold
or procedure turn)
The following circumstances cause mode reversion
without arming Vertical Path Tracking Mode:
• Navigation source manually changed from GPS
• CNCL VNV Softkey selected on the Active Flight
Plan Page (MFD)
• All remaining vertical waypoints deleted from the
flight plan
• Displays entering Reversionary Mode
Non-Path Descents
Pitch Hold, Vertical Speed, and Flight Level Change
modes can also be used to fly non-path descents while
