Method for sharing data between aeronautical equipment, related data sharing electronic system and computer program

An electronic data sharing system between equipment items, at least one equipment item being comprised in an aircraft, the aircraft carrying out a flight mission, the electronic sharing system comprising for one of the equipment items:

• an obtaining module configured to obtain a set of data coming from the equipment item, at least one datum of the set of data coming from a sensor associated with the equipment item;
• an addition module configured to add the set of data to a common group, the common group including data common to all equipment items;
• a filtering module configured to filter the data of the common group via filtering rules specific to the mission, so as to determine at least one first relevant datum, the at least one first relevant datum being relevant for the successful completion of the flight mission;
• a transmission module configured to transmit to at least one other equipment item, only the at least first relevant datum to be used among:
• a display to a respective user of the other equipment item, and computation, by another equipment, of a command of that aircraft;
• and
• a delivery module configured to:
• receive data coming from sensor(s) associated with the equipment item and/or determined by the equipment item;
• select from among the received data, second relevant data, the second relevant data being relevant for a user of the equipment item, in order to control said equipment item within the framework of the mission;
• and
• form the set of data coming from equipment item by concatenation of the selected second relevant data.
