when the user selects Altitude Hold Mode by pressing the ALT key on the GMC
control unit, or touching the ALT button on the display. The following two
options are available:
• Normal: The Flight Director enters Altitude Hold (ALT) Mode.
• Sync Selected Altitude: The Flight Director enters Altitude Hold (ALT)
Mode and the Selected Altitude (Altitude Bug) changes to the current
aircraft altitude.
• ALT Mode User Up/Down Action: Determines the behavior of the Flight
Director when the Flight Director is in Altitude Hold (ALT) Mode and the user
moves the pitch wheel on the GMC control unit, or touches Nose Up or Nose
Down on the AFCS Display. The following two options are available:
• Normal: Adjusts the Target Altitude in 10-foot increments, up to +/-200
feet from the original Target Altitude.
• Select VS Mode: The Flight Director changes from Altitude Hold (ALT)
Mode to Vertical Speed (VS) Mode and initiates a climb or descent.
Subsequent vertical speed adjustments are in increments of 100 fpm. The
Default Vertical Speed that is used for the initial climb or descent is set
using a pair of fields that appear when Select VS Mode is selected.

differs in the following ways:
NOTE: With Altitude Controls set to Simplified, the user will not be able to
pre-select a new altitude while ALT mode is already active.
