Thrust Setting Modes - Block DiagramA. Manual Thrust Setting Mode (the autothrust function is not active)
The throttle control lever installed in the cockpit center pedestal controls:
The throttle control lever installed in the cockpit center pedestal controls:
- The actual engine thrust setting
- The selection of the thrust limit mode.
The EEC: - Receives the throttle lever angle
- Computes the engine thrust limit parameter, and
- Adjusts the actual engine thrust parameter accordingly.
B. Automatic Thrust Setting Mode (the autothrust function is active)
The throttle control lever controls:
The throttle control lever controls:
- The limitation of the actual thrust
- The selection of the thrust limit mode.
The FMGC computes the target thrust parameter and sends it to the EEC.
The EEC adjusts the actual engine thrust parameter according to this value (Ref. 73-20).
The top limit value of the target thrust parameter is the current position of the throttle control lever (this is applicable when the alpha floor protection is not activated).
When the alpha floor protection is activated the throttle control lever represents the lower limit of the autothrust demand.
