Final
Report № AIFN/0010/2018, issued on 10 January 2022
21
(a) A wrong aircraft position with regard to the runway was inserted in the flight
management system (FMS). In that case, the system triggers the amber ECAM
caution ‘NAV NOT ON FMS RUNWAY’ if the take-off is on the wrong runway or
taxiway; and
(b) A take-off distance is too short based on the take-off speeds of V
R
. In that case the
system triggers the red ECAM warning ‘T.O RUNWAY TOO SHORT’.
For ABY111 flight, the Aircraft manufacturer concluded that the TOS2, the system would
have triggered:
(a)
The ECAM caution ‘NAV NOT ON FMS RUNWAY’ as the Aircraft lined up on the
wrong runway 12; and
(b)
The ECAM red warning ‘T.O RUNWAY TOO SHORT’ as the take-off runway
available was 1,000 m after the Aircraft lined up on runway 12. The Aircraft
manufacturer calculated that with the hypothesis of V
R
at 127 knots, the take-off
runway required was 1,145 m for the original Aircraft configuration of FLX/MCT
engine thrust at flap 1+F position.
