The Thrust Levers (T/L) are also an interface for pilot inputs to the
FMGCs, and to the FADEC. The Thrust Levers are shown below.
T/L functions are:
− Engagement of A/THR and FD in take off mode (thrust levers at FLX
or DRT or TOGA position), and engagement of A/THR, FD and/or AP
in go-around mode (T/L at TOGA),
− Selection of other thrust rating limits (T/L to MCT or CL),
− Setting the limit for A/THR authority, by T/L position,
− Controlling manual thrust when A/THR is not active, and reverse
thrust.
