Pitch Hold, Vertical Speed, and Flight Level Change modes can also be used to fly non-path descents
while VNAV is enabled. If the VS or FLC Key is pressed while Vertical Path Tracking Mode is selected,
Vertical Path Tracking Mode reverts to armed along with the appropriate altitude capture mode to allow
profile re-capture.
To prevent immediate profile re-capture, the following must be satisfied:
• At least 10 seconds have passed since the non-path transition was initiated
• Vertical deviation from the profile has exceeded 250 feet, but is now less than 200 feet
Pressing the VNV Key twice re-arms Vertical Path Tracking for immediate profile re-capture.
VNAV TARGeT ALTITUDe CAPTURe MODe (ALTV)
Armed VNAV Target Altitude and Selected Altitude capture modes are mutually exclusive. However,
note:
Selected Altitude Capture Mode is armed implicitly (not annunciated) whenever VNAV Target Altitude
Capture Mode is armed.
VNAV Target Altitude Capture is analogous to Selected Altitude Capture Mode and is armed automatically
after the VNV Key is pressed and the next VNAV Target Altitude is to be intercepted before the Selected
Altitude. The annunciation 'ALTV' indicates that the VNAV Target Altitude is to be captured. VNAV Target
Altitudes are shown in the active flight plan or vertical direct-to, and can be entered manually or loaded from
a database (see the Flight Management Section for details). At the same time as "TOD within 1 minute" is
annunciated in the Navigation Status Box, the active VNAV Target Altitude is displayed above the Vertical
Speed Indicator (see Figure 7-11).
As the aircraft nears the VNAV Target Altitude, the flight director automatically transitions to VNAV Target
Altitude Capture Mode with Altitude Hold Mode armed. This automatic transition is indicated by the green
'ALTV' annunciation flashing for up to 10 seconds and the appearance of the white 'ALT" annunciation.
The VNAV Target Altitude is shown as the Altitude Reference beside the 'ALTV' annunciation and remains
displayed above the Vertical Speed Indicator. The Required Vertical Speed Indication (RVSI) is removed once
VNAV Target Altitude Capture Mode becomes active.
