Abstract: An aircraft sound diagnostic method includes a step of measurement of acoustic signals by a plurality of microphones mounted at different positions inside the aircraft, a step of recording of the measured acoustic signals, a computation step which generates a sound mapping on the basis of the measured acoustic signals, a step of comparison of the sound mapping and a reference mapping and a step of transmission of the comparison to a user device. The method makes it possible to track the trending of an abnormal noise or of an abnormal noise level and assist in determining the context thereof. An aircraft sound diagnostic device for implementing the method is also described.

Abstract: A device for displaying a flight plan of an aircraft is disclosed. The device includes a control unit with at least one first display area including a textual list of identifiers of points, a textual list of identifiers of segments, or both that are representative of a portion of the flight plan. A display of the textual lists are centered around a current central display point, the current central display point corresponding to a point of the flight plan or a segment of the flight plan. The device further includes means for displacing by jumps the flight plan portion displayed in the first display area by selecting a new point different from the current central display point, the selected new point becoming a new central display point after selection thereof.

Abstract: The subject of the invention is an interactive navigation device comprising at least one navigation screen making it possible to display a graphical representation of at least one flight plan, a flight plan being composed of points and of segments. The device comprises means for displaying several flight plans simultaneously on the navigation screen at the same time as flight information text fields associated with the points of the said flight plans, the flight information fields being displayed in a manner contiguous with the points associated with them so as to be able to compare them conveniently. The device also comprises means for displaying on the navigation screen flight information fields associated with the segments of the flight plans, the said flight information fields being displayed in a manner contiguous with the segments associated with them.

Abstract: The subject of the invention is a device for displaying flight plans of an aircraft comprising a control unit with at least one first display area comprising a textual list of identifiers of points, of pseudo-points and/or of segments that is representative of a portion of the flight plan, the display of the said list being centred around a central display point, the said point corresponding to a point, a pseudo-point or a segment of the flight plan, the said device being characterized in that it comprises means for displacing by jumps the flight plan portion displayed in the first display area by selecting a different central display point from the current central display point, the said selected point becoming the new central display point.
