Abstract:
1. A method of transmitting a message between a tanker aircraft and a receiver aircraft during an in-flight refueling operation performed by a boom device deployable from the tanker aircraft and connectable to a receptacle of the receiver aircraft, the boom device and the receptacle comprising coils which establishes an electro-magnetic connection between the tanker aircraft and the receiver aircraft while connected during a refueling operation, wherein the message comprises a data message and a voice message, and the method comprises: providing in the aircraft that emits the message, a digital data frame containing the data message and a control signal, and an analog audio signal containing the voice message and a control signal; converting, in the aircraft that emits the message, the digital data frame into a digital data signal and transforming the digital data signal to an analog data signal conditioned to a suitable voltage level for transmission to the target aircraft of the message; converting the analog audio signal to a second analog audio signal conditioned to a suitable voltage level for transmission to the target aircraft and filtered to remove frequencies above a predetermined frequency f1; mixing the second analog audio signal with the analog data signal to form an analog audio and data signal; transmitting the analog audio and data signal to the target aircraft via said electro-magnetic connection; separating the analog data signal and the second analog audio signal contained in the analog audio and data signal received in the target aircraft, and transforming, in the target aircraft, the analog data signal to the digital data signal and thereafter converting the digital data signal converted to the digital data frame.
