Abstract: A system for determining an operational state of an aircrew according to an adaptive task plan. The system comprising a computer adapted to determine for the or each crew member at least one theoretical baseline crew member cognitive state according to the task list assigned to the crew member, using a resource model. The computer is adapted to determine an indicator of fitness of the or each crew member to perform the task(s) of the task list assigned to the crew member, from an actual crew member cognitive state determined on the basis of physiological measurements on the crew member and measurements of the crew member's interaction with the aircraft, and from the theoretical baseline crew member cognitive states.

Abstract: An automatic speech recognition with detection of at least one contextual element, and application to aircraft flying and maintenance are provided. The automatic speech recognition device comprises a unit for acquiring an audio signal, a device for detecting the state of at least one contextual element, and a language decoder for determining an oral instruction corresponding to the audio signal. The language decoder comprises at least one acoustic model defining an acoustic probability law and at least two syntax models each defining a syntax probability law.
