PROBLEM TO BE SOLVED: To provide a communication method for a helicopter, capable of improving communication quality by preventing a communication disturbance caused by rotor modulation.SOLUTION: In the communication method, there is used a frame composed of learning data and two types of transmission data stored in a first position and a second position. A transmitter unit duplicates the transmission data, stores the transmission data in the first position of a particular frame and stores the duplicated transmission data in the second position of another frame in which transmission is completed within a rotor passing interval (T1) from the top of the frame. The same data is transmitted a plural number of times at intervals of a predetermined time on a time axis. |
