CAUTION: The FGCP altitude must always be set to the altitude of a climb waypoint altitude that constrains
the climb path (e.g. an AT, or AT OR BELOW constraint); otherwise the aircraft will continue to
climb towards the FGCP altitude and may therefore violate the altitude constraint.
NOTE: A CHECK SELECTED ALT alert message will also be raised if the FGCP altitude is set above
an AT, or AT OR BELOW or upper limit of a WINDOW climb waypoint altitude constraint, and
the aircraft has reached an altitude where the start of capturing the altitude constraint would
normally be commanded.

1.6.4 Open Climb Guidance
During Climb, the FMS transmits to the Autopilot system and displays on the PFD a target speed; th
tracks and holds the FMS-comm
NOTE: Although the FMS-commanded climb target speed respects all waypoint speed constrai
the responsibility of the flight crew to ensure that the aircraft respects all waypo
constraints during climb.
During Climb, the FMS will continue to manage the climb target speed regardless of the
LNAV or HDG modes).
