A system and method for selecting a datum representative of an air parameter, including a plurality of sources each capable of delivering a datum representative of a measured value of the parameter. The system includes: a mechanism for determining, for at least some sources, a number of other sources from the plurality of sources in agreement with a source in question; and a mechanism for selecting the datum selected from the data delivered by the sources for which the determined agreement number is the maximum. An engine control system, or an aircraft can include such a system or implement such a method.

1. A system for selecting a datum representative of an air parameter, comprising: a plurality of redundant and independent sources that are each configured to deliver a datum representative of a measured value of the parameter;means for determining, for at least a concerned source, a number of other
1. A system for selecting a datum representative of an air parameter, comprising: a plurality of redundant and independent sources that are each configured to deliver a datum representative of a measured value of the parameter;means for determining, for at least a concerned source, a number of other sources of the plurality of redundant and independent sources in agreement with the concerned source; andmeans for choosing the selected datum to be used in a control computer from among data delivered by the plurality of redundant and independent sources for which the determined agreement number is maximum,wherein the means for choosing the selected datum is configured to be inactive when: the means for determining identifies at least four sources of the plurality of redundant and independent sources in agreement by pairs, andsources of one pair of the plurality of redundant and independent sources are not in agreement with sources of another pair of the plurality of redundant and independent sources. 2. The system for selecting according to claim 1, wherein another source is in agreement with the concerned source if an absolute value of a difference between the datum delivered by the concerned source and the datum delivered by the another source is less than a predetermined threshold. 3. The system for selecting according to claim 1, wherein the means for choosing the selected datum is configured to be inactive when: the means for determining identifies four sources of the plurality of redundant and independent sources in agreement by pairs, andsources of one pair of the plurality of redundant and independent sources are not in agreement with sources of another pair of the plurality of redundant and independent sources. 4. The system for selecting according to claim 1, wherein the concerned source is associated with a fuselage of an aircraft. 5. The system for selecting according to claim 1, wherein the sources of the plurality are located at a fuselage of an aircraft. 6. The system for selecting according to claim 1, wherein at least one of the sources of the plurality of sources is located at an engine of an aircraft. 7. A system for controlling an aircraft engine, comprising: the system for selecting a datum according to claim 1; andmeans for determining an instruction for controlling the engine according to the selected datum. 8. An aircraft comprising the system according to claim 1. 9. The system for selecting according to claim 1, wherein the means for determining includes means for determining, for each of a first number of the plurality of redundant and independent sources as the concerned source, the number of other sources of the plurality of redundant and independent sources in agreement with the concerned source,the means for choosing includes means for choosing, from a second number of the plurality of redundant and independent sources, the selected datum to be used in the control computer from among data delivered by the plurality of redundant and independent sources for which the determined agreement number is the maximum, andthe second number is less than the first number. 10. The system for selecting according to claim 9, wherein the first number of the plurality of redundant and independent sources includes at least one source located at a fuselage of an aircraft and at least one source located at an engine of the aircraft, andthe second number of the plurality of redundant and independent sources excludes the at least one source located at the engine. 11. A method for selecting a datum representative of an air parameter from among a plurality of data each representative of a measure value of the parameter and delivered by a respective plurality of redundant and independent sources, the method comprising: determining, for at least a concerned source, a number of other sources of the plurality of redundant and independent sources in agreement with the concerned source; andchoosing the selected datum to be used in a control computer from among the data delivered by the plurality of redundant and independent sources for which the determined agreement number is maximum,wherein the choosing is not implemented when: the determining identifies at least four sources of the plurality of redundant and independent sources in agreement by pairs, andsources of one pair of the plurality of redundant and independent sources are not in agreement with sources of another pair of the plurality of redundant and independent sources. 12. The method according to claim 11, wherein the choosing is not implemented when: the determining identifies four sources of the plurality of redundant and independent sources in agreement by pairs, andsources of one pair of the plurality of redundant and independent sources are not in agreement with sources of another pair of the plurality of redundant and independent sources. 13. The method according to claim 11, wherein the determining includes determining, for each of a first number of the plurality of redundant and independent sources as the concerned source, the number of other sources of the plurality of redundant and independent sources in agreement with the concerned source,the choosing includes choosing, from a second number of the plurality of redundant and independent sources, the selected datum to be used in the control computer from among the data delivered by the plurality of redundant and independent sources for which the determined agreement number is the maximum, andthe second number is less than the first number. 14. The method according to claim 13, wherein the first number of the plurality of redundant and independent sources includes at least one source located at a fuselage of an aircraft and at least one source located at an engine of the aircraft, andthe second number of the plurality of redundant and independent sources excludes the at least one source located at the engine.
