• The speed reference system (SRS) mode remains engaged until CLB phase is engaged,
which occurs at ACCEL ALT or at any other vertical mode engagement, whichever comes
first.
• If during takeoff the FCU altitude is set below the current aircraft altitude, the system ignores
the FCU altitude and the aircraft remains in SRS mode until the pilot selects an altitude above
the aircraft altitude or engages any other mode.
PRESELECTING A HDG OR A TRK
Applicable to: ALL
PROCEDURE
If a HDG or a TRK was preselected on the ground :
PULL OUT the HDG/TRK selector knob when required
CHECK that the HDG/TRK mode is active and displayed on the FMA
When a HDG or TRK is preset, OP CLB mode will engage at the acceleration altitude. (CLB
mode is not available in HDG/TRK mode).

NORMAL TAKEOFF PROFILE
Applicable to: ALL
NO FLIGHT DIRECTOR TAKEOFF
Applicable to: ALL
If a takeoff is initiated without FDs, the system responds as follow :
‐ There are no FD bars.
‐ There is no A/THR arming.
‐ There is no guidance available.

The target speed on the PFD is that selected ‐ on the FCU or is defaulted to 100 kt.
‐ Setting the thrust levers to the CL detent does not activate A/THR.
Note: Do not engage the autothrust prior to selecting a target speed on the FCU.
PROCEDURE
Establish initial climb of 15 °
When reaching the thrust reduction altitude (THR RED ALT) :
SELECT a climb speed.
SET the thrust levers to CL detent.
ACTIVATE the autothrust.
TURN ON the FDs (basic modes engage).
SELECT appropriate mode.

Failure of both FDs after the start of takeoff :
• The FD bars disappear.
• The FCU window displays the target speed, which synchronizes on V2, or the current speed
(if it is higher).
• The autothrust remains armed.
• At thrust reduction altitude, LVR CLB flashes. If the pilot set the thrust levers to the CLB
detent, the autothrust becomes active in selected SPD mode (no FDs selected).
If the current speed is greater than the target speed, the thrust decreases.
• At acceleration altitude the target speed does not change, since it is selected.
TAKEOFF WITH NO V2 ENTRY
Applicable to: ALL
If V2 is not inserted, the speed reference system (SRS) will not engage for takeoff.
Five seconds after lift off, V/S mode will engage. When V/S engages the current airspeed becomes
the FCU target speed.
To regain a normal speed target, the pilot must :
SELECT the appropriate climb speed on the FCU and PULL out the knob.
At ACC ALT :
PUSH the A/THR pushbutton on the FCU.
SET the thrust levers to CL detent.
PUSH in the SPD selector knob to get a managed speed target.
TAKEOFF USING THE LOCALIZER OF THE OPPOSITE RUNWAY
Applicable to:
If the localizer, of the ILS associated with the opposite runway, must be used for takeoff :
SELECT the RAD NAV PAGE.
ENTER the ILS IDENT.
If the ILS is in the database, the system tunes the proper frequency.
Check that the ILS front course is displayed in the CRS field.
Note: This may trigger the “RWY/ILS MISMATCH” message. Disregard it.

If the ILS is not in the database :
SET the appropriate frequency, and SET the ILS front course in the CRS field.
DESELECT the ILS pushbutton on the FCU.
Since the PFD displays reverse deviation.
SELECT ROSE ILS on one ND.
