摘要

PROBLEM TO BE SOLVED: To select an optimal antenna for communication with a comrade plane from a plurality of antennas.SOLUTION: A controller 22 of an aircraft 10 comprises: a computer 26 for predicting the current position of a comrade plane 10B on the basis of a time change in comrade plane position information indicating the position of the comrade plane 10B; an antenna selection unit 32 for selecting an antenna 12, an elongation &phgr;from the central axis of which at the predicted current position of the comrade plane 10B predicted by the computer 26 is within a coverage &thetas;, from a plurality of antennas 12; and a beam control unit 34 for performing communication with the comrade plane 10B via the antenna 12 selected by the antenna selection unit 32.
