Abstract:
1. A device for detecting lack of reaction of a crew of an aircraft to an alarm regarding the danger related to a path of the aircraft, the device comprising: an alarm monitoring device for automatically monitoring the emitting condition of a plurality of alarms regarding dangers related to the path of the aircraft; a first internal determining device for automatically determining, in case one of the alarms is emitted, a first time interval, for the crew to react to the alarm emitted by implementing at least one procedure to cope with the danger causing the emitted alarm; a crew monitoring device for automatically monitoring the reaction of the crew without implementing an automatic avoidance operation during the first time interval; an instruction generation device and a signalling device automatically emitting an auxiliary alert signal, if at the end of the first time interval from the emitted alarm, the crew has not reacted to the emitted alarm; a second internal determining device for automatically determining a second time interval, for the crew to react to the alarm by implementing a procedure for coping with the danger, the second time interval being determined only if at the end of the first time interval, the crew has not reacted to the alarm; and an avoidance path generation device and an auto pilot device for automatically implementing, if at the end of the second time interval the crew has not yet reacted to the alarm, an automatic avoidance operation along an avoidance path for coping with the danger, the avoidance operation being implemented only if such an avoidance path can be calculated.
