DISENGAGEMENT CONDITIONS
The CLB mode disengages, if one of the following conditions is met:
‐ NAV mode is lost or disengaged (OP CLB engages). In this case, the reversion to OP CLB is
accompanied by a triple click aural warning
‐ Another vertical mode engages
‐ The flight crew selects an altitude on the FCU that is lower than the present aircraft altitude.
V/S (FPA) engages ong the current V/S (FPA).
Applicable to: ALL
GUIDANCE
Climb mode guides the aircraft up to the FCU selected altitude. It tries to respect speed and altitude
constraints. The AP/FD pitch controls the speed or Mach number target while the A/THR controls the
thrust set at maximum climb thrust.
When climb mode is engaged (always associated with lateral NAV mode):
‐ The system takes into account all constraints either defined by the database, or manually entered
by the flight crew
‐ The system arms ALT mode and displays the next applicable altitude target on the PFD altitude
scale.
• ALT is magenta on the FMA second line and the altitude value is displayed in magenta on the
PFD scale if the next altitude target is a constraint
• ALT is blue on the FMA second line and the altitude value is displayed in blue on the PFD
altitude scale if the next altitude target is the FCU selected altitude. In climb mode, the system
does not modify the target speed to match the altitude constraints. The flight crew has to select
it manually using the information displayed on the PROG page.
When the aircraft levels off at an altitude constraint, CLB mode arms. It will engage automatically
when the waypoint is sequenced. (If the FCU selected altitude is above the constraint).
