Abstract: A system is (10) for determining a flight rest scenario for an aircraft crew (12) comprising at least two pilots able to fly the aircraft (12) during a flight. The system (10) comprises a display device (16) comprising a screen (20), a module (32) for acquiring flight context and constraints inputs, and a module (34) for determining at least one crew rest scenario for the flight from the acquired inputs. The determination module (34) is able to determine the rest scenario from at least one simulation by a biomathematical fatigue model having at least one of the acquired inputs as variables. The system also includes a display management module (36) configured to display the determined rest scenario on the screen (20) of the display device (16).

Abstract: A device for waking up a crew member resting on an aircraft includes a processing unit configured to detect current development parameters of the aircraft and/or to detect a state of consciousness of at least one other active crewmember. The processing unit is also configured to activate an apparatus for waking up the resting crew member, when at least one predetermined condition for waking up the resting crew member on one or several current parameters of the aircraft and/or on a parameter representative of the state of consciousness of the at least one other active crew member is satisfied.
