Thrust Setting Modes-Block DiagramA. EPR Mode
(1) Manual thrust setting mode (the autothrust function is not active)
The throttle control lever in the cockpit center pedestal controls:
The throttle control lever in the cockpit center pedestal controls:
- the actual engine thrust setting
- the selection of the thrust limit mode
- receives the throttle lever angle
- computes the engine thrust limit parameter and
- adjusts the actual engine thrust parameter accordingly.
(2) Automatic thrust setting mode (the autothrust function is active)
The throttle control lever controls:
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 actual 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.
The throttle control lever controls:
- the limitation of the actual thrust
- the selection of the thrust limit mode.
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 actual 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.
B. N1 Reversionary Mode
When N1 reversionary mode is selected, the automatic thrust setting mode (autothrust active) cannot be activated.
The throttle control lever in the cockpit center pedestal controls the actual thrust setting.
The EEC receives the throttle lever angle and adjusts the actual engine thrust parameter according to ambient conditions.
When N1 reversionary mode is selected, the automatic thrust setting mode (autothrust active) cannot be activated.
The throttle control lever in the cockpit center pedestal controls the actual thrust setting.
The EEC receives the throttle lever angle and adjusts the actual engine thrust parameter according to ambient conditions.
