An electronic circuit for determining a datum representative of a parameter of air surrounding an aircraft, comprising: a first processor configured to receive, from a plurality of sources, respective measurement data representative of a measured value of the parameter of air surrounding the aircraft,determine the datum representative of the parameter of air surrounding the aircraft based on the measurement data from the plurality of sources, andtransmit the determined datum representative of the parameter of air surrounding the aircraft only to a first computer associated with a first engine of the aircraft,wherein the first processor performs the determining of the datum representative of the parameter of air surrounding the aircraft by comparing the measurement data from the plurality of sources and by selecting the datum representative of the parameter of air surrounding the aircraft from among the measurement data from the plurality of sources, anda second processor, different from said first processor, configured to receive, from the plurality of sources, the respective measurement data representative of the measured value of the parameter of air surrounding the aircraft,determine the datum representative of the parameter of air surrounding the aircraft based on the measurement data from the plurality of sources, andtransmit said determined datum representative of the parameter of air surrounding the aircraft only to a second computer, different from said first computer, associated with a second engine of the aircraft,wherein said determined datum representative of the parameter of air surrounding the aircraft transmitted to said first computer associated with said first engine is the same as said determined datum representative of the parameter of air surrounding the aircraft transmitted to said second computer associated with said second engine. 2. An electronic circuit according to claim 1, wherein each of said first and second processors is configured to determine, for certain data at least among the measurement data from the plurality of sources, a number of other measurement data in agreement, and to choose the datum representative of the parameter of air surrounding the aircraft from among the measurement data for which the number of other measurement data in agreement is maximum. 3. An electronic circuit according to claim 1, wherein each of said first and second processors is configured to transmit the datum representative of the parameter of air surrounding the aircraft over a corresponding communication bus of the aircraft. 4. A system for determining a datum representative of a parameter of air surrounding an aircraft, comprising: a plurality of sources each configured to transmit a measurement datum representative of a measured value of the parameter of air surrounding the aircraft;a first electronic circuit to receive the measurement data transmitted by the plurality of sources, to determine the datum representative of the parameter of air surrounding the aircraft based on the measurement data received from the plurality of sources, and to transmit the determined datum representative of the parameter of air surrounding the aircraft;a first control computer associated with a first engine of the aircraft and configured to receive the transmitted datum and to control the first engine according to the transmitted datum,wherein the first electronic circuit selects the datum representative of the parameter of air surrounding the aircraft from among the measurement data from the plurality of sources;a second electronic circuit, different from said first electronic circuit, to receive the measurement data transmitted by the plurality of sources, to determine the datum representative of the parameter of air surrounding the aircraft based on the measurement data received from the plurality of sources, and to transmit the determined datum representative of the parameter of air surrounding the aircraft; anda second control computer, different from said first control computer, associated with a second engine of the aircraft and configured to receive the transmitted datum and to control said second engine according to the transmitted datum,wherein the determined datum representative of the parameter of air surrounding the aircraft transmitted to said first control computer associated with said first engine is the same as the determined datum representative of the parameter of air surrounding the aircraft transmitted to said second control computer associated with said second engine,wherein the first electronic circuit transmits the determined datum only to the first control computer and not the second control computer, andwherein the second electronic control circuit transmits the determined datum only to the second control computer and not the first control computer. 5. A system for determining according to claim 4, wherein each source of the plurality of sources is located at a fuselage of the aircraft. 6. A system for determining according to claim 4, wherein at least one source among the plurality of sources is located at said first engine of the aircraft and another source among the plurality of sources is located at said second engine of the aircraft. 7.
