10. A method for controlling a thrust reverser system connected to at least one engine of an aircraft, wherein the thrust reverser system comprises a detector, a speed detector, a radio altimeter, a position sensor, and levers comprising:
detecting a condition for activation of a reverse idle control by:
collecting speed detected by the speed detector,
collecting an altitude emitted by the radio altimeter,
determining a position of the levers, and
determining the angle of descent or climb of the aircraft,
activating the reverse idle control,
detecting a condition for activation of the thrust reverser by:
determining if the weight of the aircraft rests on wheels of landing gear; and
when the weight of the aircraft rests on the wheels of the landing gear, activating the thrust reverser, and
detecting a condition for activation of the reverse idle control.
