A system for automatically managing engine control modes of a multi-engine aircraft is disclosed. The system () can comprise means () for automatically switching all the controlling units () of the engines of the aircraft to an alternative controlling mode, as soon as one of such controlling units () is brought to such an alternative controlling mode.

Automatic managing system of engine control modes of a multi-engine aircraft

A device for controlling engine speed of a multi-engine aircraft includes a series of components for automatically controlling the speed of the engines during the take-off, so as to avoid discrepancies in the engine speeds. To this end, as long as all engines of the aircraft do not have, at least at given intermediary moment of the take-off, a driving parameter value equal to a preset intermediate value of the parameter, the speed of all of the engines cannot exceed an intermediate speed associated with the preset intermediate value. Thus, all engines must reach the intermediate speed so that the acceleration to a higher take-off speed can continue simultaneously for all engines.

Method and device for controlling engine speed of an aircraft during a take-off

A system for controlling at least one aircraft engine and an aircraft comprising such a control system are disclosed. The system () comprises a control lever (), the intermediary range of automatic regulation thereof of the engine speed comprises a single marked position (II) with which there are associated a climbing speed and an automatic regulation speed. Such a lever is able to occupy another take-off and go-around marked position, with which there are associated a take-off speed and a go-around speed.

System for controlling at least one aircraft engine and an aircraft comprising such a control system

A device for confirming the engine thrust of an aircraft is disclosed. The device, via an operating logic unit () of each engine processing different information, including a warning indicator () connected to the unit () delivers or not thrust confirmation information at the level of the cockpit.

Device for confirming the engine thrust of an aircraft

A system for supervising the speed of at least one engine of an aircraft includes three independent information sources determining first, second and third values for an aerodynamic parameter of the aircraft and precision information indicating the precision of these values. A control unit acts on the operation of the engine, and a sensor measures a fourth value for the parameter. An arithmetic unit selects a control value by using the first, second, third and fourth values of the aerodynamic parameter and the precision information and uses the control value to determine a control sequence for the control unit. An information transmission network, to which the three independent information sources and the arithmetic unit are connected, permits a transmission of information between the sources of information and the arithmetic unit.
