ENTERING A FLEX TEMPERATURE
WRITE FXX (XX being 2 digits).
ENTER the FLEX temperature using the [4R] key.
The thrust limit mode and the N1 rating limit are displayed on the ECAM E/WD.
ENTERING A DERATED LEVEL
WRITE DXX (XX being 2 digits). Six derate levels are possible : 04, 08, 12, 16, 20, 24 %.
CONFIRM the selection with the [4R] key.
The thrust limit mode and the N1 rating limit are displayed on the ECAM E/WD.

CLIMB SPEED PRESELECTION
If the managed speeds for the initial climb are not suitable, the pilot can preselect an appropriate
climb speed on the “PERF CLB” page as long as the climb phase is not active.
The CLB SPD preselection applies when :
‐ ATC specifies an initial climb speed.
‐ The initial climb speed must be lower than normal because :
• There will be turned greater than 120 ° in the initial climb.
• Obstacle clearance or some other situation requires a high climb angle.
• The airfield has a risk area to be cleared expeditiously (birds reported, for example).

PROCEDURE
PRESS the PERF key on MCDU
PRESS the NEXT PAGE on MCDU
WRITE a climb speed and ENTER it in [4L]
To revert to managed speed, select MANAGED by pressing [3L] key.
When the aircraft is transitioning into the climb phase, the preselected value becomes the target
speed :
‐ The selected speed target is active.
‐ The primary flight display shows the target speed in blue.
‐ The speed window of the FCU displays the new speed or Mach number.
Applicable to: ALL
CRUISE MACH (SPEED) PRESELECTION
The pilot preselects a cruise Mach when it requires a Mach number other than the economy cruise
Mach number.
When the aircraft transitions to the cruise phase, the speed target symbol goes to the preselected
value and MACH (or SPD) becomes selected (blue target on PFD, target MACH shown in the
speed/Mach window of the FCU).

PROCEDURE
PRESS the PERF key on MCDU
PRESS the NEXT PAGE key on MCDU until the CRZ page is accessed.
WRITE a cruise Mach (or speed) into the scratchpad and ENTER it in [4L].
To revert to managed speed, PRESS the [3L] key.
The pilot may modify the cruise Mach or speed on ground or in climb. When the cruise phase is
active, the pilot cannot preselect a cruise Mach or speed.
Applicable to: ALL
ENTERING A HEADING/TRACK PRESET FUNCTION
The heading/track preset allows the pilot to preset a heading or a track for takeoff or goaround
before he commands the aircraft to take up that heading or track (manual activation).
The flight crew can enter a heading or a track preset while the aircraft is on the ground and until
takeoff.

FCOM 19 AUG 10
PROCEDURE
Before takeoff :
SET the appropriate HDG or TRK in the FCU window.
This disarms the navigation mode and allows the runway mode to remain engaged after takeoff.
To activate the preset after takeoff :
PULL the HDG/TRK selector knob.
The heading or track mode engages on the preset value.
The direction the pilot rotates the HDG/TRK selection knob usually determines the direction of
the turn. A left rotation (decreasing heading) produces a left turn ; a right rotation produces a
right turn.
However, when a heading has been preset before takeoff or a go-around, the direction of the
turn will be such as to cause the shortest turn at the moment of engagement.
