The present disclosure provides a computer implemented method of providing an indicator useful for piloting an aircraft. The aircraft comprises an antenna configured to communicate with a transceiver. The method comprises: obtaining an antenna envelope characterizing directions relative to the aircraft for which a directive gain of the antenna exceeds a predetermined threshold; determining a direction of the transceiver relative to the aircraft; calculating a maneuvering range of the aircraft by comparing the antenna envelope and the transceiver direction, wherein the maneuvering range is indicative of eligible orientations of the aircraft for maintaining the transceiver within the antenna envelope; and outputting data indicative of the maneuvering range.

The method according to claim 1, wherein when the transceiver direction is out of the antenna envelope, the maneuvering range is empty. 3. The method according to claim 1, wherein the predetermined threshold is variable with respect to a direction relative to the aircraft. 4. The method according to claim 1, wherein the data indicative of the maneuvering range comprises at least one of roll and pitch variation maximum values to maintain the transceiver within the antenna envelope. 5. The method according to claim 4, wherein the at least one of roll and pitch variation maximum values include a tolerance margin. 6. The method according to claim 1, further comprising: determining a recovery range of the aircraft, the recovery range defining potential orientations of the aircraft for returning the transceiver within the antenna envelope; andoutputting data indicative of the recovery range. 7. The method according to claim 6, wherein when the transceiver direction is in the antenna envelope, the recovery range is empty. 8. The method according to claim 6, wherein the data indicative of the recovery range comprises at least one of roll and pitch variation minimum values to return the transceiver within the antenna envelope. 9. The method according to claim 1, wherein obtaining the antenna envelope is performed using data indicative of a reference antenna radiation pattern. 10. The method according to claim 9, wherein the reference antenna radiation pattern involves a scanning capability of at least the antenna and interferences between the antenna and the aircraft structure. 11. The method according to claim 9, wherein obtaining the antenna envelope is performed by accessing prestored data indicative of directions relative to the aircraft for which the reference antenna radiation pattern exceeds a default threshold. 12. The method according to claim 9, wherein obtaining the antenna envelope comprises updating the predetermined threshold and determining the antenna envelope using the updated predetermined threshold and the reference antenna radiation pattern. 13. The method according to claim 9, wherein obtaining the antenna envelope comprises detecting obstruction from a scene relief using topographical data. 14. The method according to claim 6, wherein at least one of the data indicative of the maneuvering range and the data indicative of the recovery range are output to a control system of an unmanned aircraft vehicle, which is remote from the unmanned aircraft vehicle. 15.
