Abstract: Method and device for an optimal management of the slats, the flaps and the landing gear of an aircraft. The device (1) includes means (5) for determining, in an iterative manner, according to a predicted energy state, optimal commands of means (10, 11) for controlling the slats, the flaps and the landing gear of the aircraft, which allow the aircraft to reach a given point of a trajectory in a given energy state with a given aerodynamic configuration and a given position of the landing gear.
Abstract: A landing gear monitor for aircraft landing gear including a plurality of pairs of wheels on a bogie, in which the main strut oil pressure serves to indicate landing load and is monitored in relation to, respectively, the two-wheel mode and the four-wheel mode, the two-wheel mode being the condition when a first of the plurality of pairs of wheels on the bogie contacts the ground and the four-wheel mode being the condition of a first and a second of the plurality of pairs of wheels on the bogie being in full contact with the ground.

Abstract: The present invention relates to an improved architecture for an aircraft. The aircraft has a first engine, a first gearbox associated with the first engine, a first starter/generator associated with the gearbox, and a first motor drive connected to the first starter/generator for providing the starter/generator with electric power to start the first engine and to receive electric power from the starter/generator after the engine has been started to operate electrically driven systems onboard the aircraft. The aircraft preferably further has at least one other engine which has a gearbox and a starter/generator associated with it and at least a second motor drive connected to the starter/generator. The electrically driven systems operated by the motor drive(s) include an environmental control system, a wing anti-icing system, an aircraft control system, and the aircraft fuel system.
