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
First Claim
1. A method for transmitting in flight data recorded by a black box of an aircraft, the method comprising emitting by the aircraft a radioelectric beam conveying said data along a first directivity if at least one predetermined parameter does not indicate a critical condition of the aircraft, and along a second directivity different from the first directivity if the predetermined parameter indicates a critical condition of the aircraft wherein the emitted radioelectric beam (F1, F2) is generated by:
- activating a set of antennas (A1-An) of the aircraft, if the parameter does not indicate a critical condition of the aircraft, andselectively activating a sub-set (Ai) of the set of antennas, if the parameter indicates a critical condition of the aircraft.

Abstract
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).

12. A transmission system for an aircraft comprising:
-
a flight recorder of the black box type, an emitter of a radioelectric beam conveying data collected by the flight recorder, the system being characterized in that it further comprises; a diagnostic module configured for determining at least one parameter either indicating or not a critical condition of the aircraft, and a control module configured for adjusting the directivity of the emitter according to the determined parameter wherein the emitter (A) comprises a plurality of antennas (A1-An), and wherein the control module (C) is configured for; activating the plurality of antennas (Ai-An) if the parameter does not indicate a critical condition of the aircraft, and selectively activating a sub-set (Ai) of the plurality of antennas if the parameter indicates a critical condition of the aircraft. - View Dependent Claims (13, 14)
