METHOD OF TRANSMITTING FLIGHT DATA RECORDED BY A BLACK BOX OF AN AIRCRAFT BY A RADIOELECTRIC BEAM WHOSE DIRECTIVITY CHANGES IF A CRITICAL STATE OF THE AIRCRAFT IS DETECTED

摘要

There is proposed a method of in-flight transmission of data recorded by a black box of an aircraft (1), the method comprising the emission (600) by the aircraft (1) of a radioelectric beam (F1, F2) transporting said data according to a first directivity (D1) if at least one predetermined parameter does not indicate a critical state of the aircraft (1), and according to a second directivity (D2) different from the first directivity (D1) if the predetermined parameter indicates a critical state of the aircraft (1).
