Engine Thrust Levers

Thrust Lever Detents

THRUST LEVER DESCRIPTION - Two thrust levers control engine thrust, or set the authority of the auto thrust system. The levers can only be moved manually; they do not move automatically.

When the thrust levers are moved, they transmit signals to the FADEC, which computes the thrust rating limit and EPR. If a thrust lever is set in a detent, the FADEC selects the rating limit corresponding to that detent. If the thrust lever is set between two detents, the FADEC selects the rating limit corresponding to the higher detent. This limit is displayed on the upper ECAM.

There are five positions defined by stops or detents:

  • Takeoff / Go-Around (TO/GA)
  • Flex/Max Continuous Thrust (FLX/MCT)
  • Climb (CL)
  • Forward Idle
  • Max Reverse
