An aircraft radio comprises a transmitter configured to transmit wireless
signals over a transmit frequency; a receiver configured to receive
wireless signals over a receive frequency; and a processing unit
configured to adjust the transmission frequency of the aircraft radio
based on received sensor data in order to avoid interference with other
wireless transmissions; wherein the processing unit is further configured
to determine if a ground station is in range of the aircraft radio and to
communicate directly with a second aircraft radio on another aircraft
when a ground station is not in range.
