Abstract: A collision avoidance device for an aircraft of the type comprises means for the geographical localization of the aircraft, means for the computation, for each geographical place, of a safety floor above which the aircraft must be positioned, means to predict the position in the air of the aircraft between a first given instant and a second given instant and means to compare the predicted position in the air of the aircraft with respect to the specified security floor. The safety floor, which is used for the comparison, is consolidated beforehand by means of a sensor that detects the obstacles in a forward sector of the aircraft and provides means with measurements enabling the computation of the altitude of these obstacles with respect to a reference level. The disclosed device has the advantage of enabling a reduction in the risk of delayed alarms and harmful alarms.

Abstract: A device for assisting the extinguishing of fires by water-bombing aircraft. The device includes at least one sensor for sensing the source of the fire, a device for pinpointing the position of the aircraft, a geographical database and a calculator for calculating the route of the aircraft as a function of its position and the position of the source as pinpointed in the database.

Abstract: A device to control an aircraft system in manual pilot mode, using notably a head-up display, is constituted by a display screen located at the position of a piece of equipment of the right-hand part of the instrument panel, the screen displaying information elements delivered by the replaced equipment and information elements to control the piloting task. Application for the controlling of a manual pilot phase by a co-pilot in an aircraft using a head-up display.

Abstract: The disclosure is an aircraft landing aid device that includes at least a database containing signatures and positions of reference objects, a sensor picking up signatures of reference objects, means of navigation used to fix the approximate position of the aircraft, means of correlation connected to said means of navigation, sensor and database, that define the vertical and horizontal bearings of the objects picked up by said sensor, and means of fixing the exact position of the aircraft, connected to said means of navigation, sensor and database. It is applicable in particular to airliners, enabling landing in all weather conditions.

Abstract: The disclosure is an aircraft collision-avoidance device used notably during landing approach. The device includes at least means of fixing the position of the aircraft, a database, first means of comparison, means of extraction of the point of touch-down on the runway, means of calculating the real glide slope vector of the aircraft, means of extraction of the theoretical glide slope vector of the aircraft, and second means of comparison used to compare the real and theoretical slope vectors. It is applicable in particular to airliners during final approach to landing.
