Patent ID: 8384563

Claim:
A device for confirming a thrust of at least one engine of an aircraft while it is running on a ground surface, upon a take-off phase thereof, such a device comprising: at least one display screen ( 2 ) in a cockpit of the aircraft permanently displaying at least one control parameter of each engine allowing to check the thrust delivered by one of them; an operating logic unit ( 14 ) for each engine, receiving at least information on said control parameter of said engine when said thrust is reached, on the take-off mode position of a throttle lever corresponding to said engine and on a ground position of said aircraft; and a warning indicator connected at an outlet of said logic unit and able to display, at a level of said cockpit, thrust confirmation information when said information received by said logic unit is validated, wherein said logic unit ( 14 ) comprises, for each engine, at least an AND gate ( 24 ) receiving, at respective inlets thereof, said information on the control parameter of said engine, on the take-off mode position of said throttle lever, and on the ground position of said aircraft, and, when said information is gathered and validated, delivers, at the outlet thereof, said thrust confirmation information in a direction of said warning indicator ( 15 ), and wherein said logic unit ( 14 ) further comprises, for each engine: an OR gate ( 34 ) receiving at the respective inlets thereof at least information on a lack of thrust by said engine, on a position of the throttle lever other than that relating to the take-off mode, on a flight position of the aircraft and on a velocity of the aircraft higher than a take-off decision velocity; and a toggle ( 28 ) at the inlets of which there are received said outlet information delivered by said AND gate ( 24 ) and said outlet information delivered by said OR gate ( 34 ), and the outlet of which is connected to said warning indicator ( 15 ).
