  • Device for detecting the state of a switch
    Patent number: 9064649
    Abstract: A device for detecting the state of a switch. The device includes a detection circuit which delivers a signal of specified value (Vpullup) when the value of an electrical quantity (RSw) characterizing the state of the switch is less than a threshold called the lower threshold (Rclosed) and/or a signal of different value when the value of the electrical quantity is greater than a threshold different from the lower threshold, called the upper threshold (Ropen). The disclosed embodiments also concern flight control systems, in which the device is implemented, and the aircraft including the systems.

  • Engine speed control device, a method for controlling engine speed and an aircraft provided therewith
    Patent number: 7975671
    Abstract: An engine speed control device includes an engine speed control lever that generates an engine speed instruction and a device for delivering the indicative information on the actual engine speed. An actuator applies a mechanical force on the lever according to the difference between the instruction and the indicative information on the actual engine speed.

  • Engine Speed Control Device, a Method for Controlling Engine Speed and an Aircraft Provided Therewith
    Publication number: 20090126683
    Abstract: An engine speed control device comprises an engine speed control lever (2) generating an engine speed instruction (POS) and means for delivering the indicative information (&thetas;e) on the actual engine speed. Actuating means (8, 10) are designed in such a way that a mechanical force can be applied on the lever (2) according to the difference between the instruction (POS) and the indicative information (&thetas;e) on the actual engine speed. Said device is suitable for an aircraft. The engine speed control method is also disclosed.
