Method and a device for detecting lack of reaction from the crew of an aircraft to an alarm related to a path
First Claim
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.

Abstract
A method and a device are provided for detecting lack of reaction of the crew of an aircraft to an alarm related to a path. The method includes monitoring the emitting condition of a plurality of alarms related to dangers in the path of the aircraft and monitoring a reaction of a crew during first and second time intervals determined based on how long the crew should take to response to the initial alarm in the first time interval and an auxiliary alarm in the second time interval. The method also includes implementing automatic avoidance operation for coping with the danger if the crew has not reacted to the alarms by the end of the second time interval.

3. A method for detecting lack of reaction of a crew of an aircraft to an alarm regarding a danger related to a path of the aircraft, the method comprising the following steps carried out automatically:
-
(a) monitoring the emitting condition of a plurality of alarms regarding the dangers related to the path of the aircraft; (b) in case one of the alarms is emitted, determining a first time interval for the crew to react to the emitted alarm by implementing at least one procedure for coping with the danger this alarm originates from; (c) monitoring the reaction of the crew during the first time interval without implementing an automatic avoidance operation during the first time interval; and (d) only if at the end of the first time interval from the emission, the crew has not reacted to the alarm, performing the following operations; (d1) emitting at least one auxiliary alert signal; (d2) determining a second time interval for the crew to react to the emitted alarm by implementing a procedure for avoiding the danger the emitted alarm originates from; and (d3) if at the end of the second time interval the crew has not yet reacted to the emitted alarm, implementing an automatic avoidance operation along an avoidance path for coping with the danger, the avoidance operation being implemented only if such avoidance path can be calculated. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)
