PRO-NOR-SRP-01-10 P 25/32
TAKEOFF WITH NO WEIGHT/CG DATA
If the crew does not enter ZFW/ZFWCG data prior takeoff, or if the FMGC looses these values due
to a power interruption, the following will occur:
‐ At takeoff, the Speed Reference System (SRS) mode is available (provided a V2 has been
inserted)
‐ When the aircraft leaves the SRS mode, the target speed becomes the current speed and
reverts to selected.
Note: If the AP/FD has reverted to ALT or V/S (FPA) mode, the associated A/THR mode is
SPEED. In this case, the system will probably reduce thrust, because the speed will be
equal to, or greater than, the target speed.
