AUTO –
• the altitude selector changes in 100 foot increments
• displays the selected BARO minimum as the selector passes through that
altitude. If the BARO minimum is not a 10 foot increment, displays the
next highest 10 foot increment
• When rotated rapidly, the displayed altitude changes at two to four times
the normal rate
1000 – the altitude selector changes in 1,000 foot increments.
Rotate – sets the altitude in the altitude window and on the PFD, HUD and VSD
altitude indication displays.
Push –
• during climb or descent with altitude constraints, each push deletes the
next waypoint constraint between the airplane altitude and the altitude
window
• during climb with no altitude constraints, and the altitude window set
above the FMC cruise altitude, the cruise altitude is changed to the altitude
window value
• during cruise:
• with the altitude window set above or below FMC cruise altitude, the
FMC cruise altitude resets to the altitude window altitude
• if in VNAV PTH or VNAV ALT pitch mode, the airplane begins a
climb or descent toward the altitude window altitude
• within 50 NM of the top–of–descent (T/D) point, with the altitude
window set below cruise altitude, the airplane initiates the descend now
(DES NOW) feature
Push –
• engages altitude (ALT) as the pitch mode
• ALT is displayed on the PFD and HUD pitch flight mode annunciator
• the AFDS commands pitch to maintain the altitude when the switch was
pushed
Illuminated (white) – the altitude hold mode is engaged.
Push – transfer the value from the lower line to the upper line. Lower line blanks
after the transfer.
