DERATED CLIMB
Applicable to: ,
GENERAL
The derated climb (DCLB) reduces the thrust during climb in order to increase the engine life. The
crew can select two derated climb ratings :
DCLB1 reduces the ‐ maximum climb thrust by 5 to 10 %.
‐ DCLB2 reduces the maximum climb thrust by 10 to 15 %.
The FADEC reduces the difference between derated and maximum climb thrust with the
altitude, until zero at high altitude ; The ceiling is therefore not affected by the derated climb.
The performance for each derated thrust is given in the IN FLIGHT PERFORMANCE, Refer to
PER-CLB-AEO-CLB USE OF DERATED CLIMB.
Note: The derated climb does not depend on autothrust, autopilot or flight director engagement.
SELECTION
The crew can select DCLB 1 or 2 on the DRT CLB field of the PERF CLB MCDU page during
PREFLIGHT, TAKEOFF, CLIMB or GO-AROUND (with change of destination) phases. During any
other phase, the DRT CLB field is not available.

ACTIVATION
The derated climb becomes active during the CLIMB phase when the thrust levers are set at or
below the CLB detent.
Note: If the flight plan includes several climb phases (or step climb), the derated climb is
available only during the first CLIMB phase.
DEACTIVATION
The derated climb is deselected when one of the following condition is met :
‐ Manually cleared on MCDU, or
‐ One of the thrust levers is set to MCT or above (in flight), or

ENGINE START ON BATTERIES
Applicable to:
Note: This procedure can be followed when the aircraft electrical network is only supplied with
batteries.
Make sure that pneumatic power is available for starting the engines.
Perform an autostart on engine 2.
The secondary engine parameters are not available as long as the aircraft electrical network is
supplied by the batteries.
Note: It is required to start first a LH engine since the Xbleed valve does not open automatically
on batteries. Moreover, the parking brake is pressurized by engine 2.
When all the parameters are stabilized,
Check that the aircraft electrical network is normal.
Start the second engine following the autostart procedure.
ENGINE START ON BATTERIES
Applicable to: ,
Note: This procedure can be followed when the aircraft electrical network is only supplied with
batteries.
Make sure that pneumatic power is available for starting the engines.
Perform a manual start on the LH engine following the MAN ENG START procedure.
The secondary engine parameters are not available as long as the aircraft electrical network is
supplied by the batteries.
Note: It is required to start first the LH engine since the Xbleed valve does not open automatically
on batteries. Moreover, the parking brake is pressurized by the LH engine.
The EEC remains in unrated mode for 4 min. Follow the ECAM procedure to recover the
normal EPR mode.
When all the parameters are stabilized,
check that the aircraft electrical network is normal.
Start the second engine following the autostart procedure.
