PROBLEM TO BE SOLVED: To effectively reduce deviation of output power between channels in a mounted amplifier 3, in a helicopter-mounted amplification system mounting the amplifier 3 on a helicopter. SOLUTION: The helicopter-mounted amplification system includes: a transmission device 1 for outputting a signal to be transmitted; the amplifier 3 for amplifying a signal outputted from the transmission device 1; a radio transmission means 4 for wirelessly transmitting the signal amplified by the amplifier 3; and a post-amplification level-notifying means 5 for notifying the transmission device 1 of information about a level of the signal amplified by the amplifier 3. The transmission device 1 includes a level control means for controlling a level of outputting a signal to be transmitted based on the information reported by the post-amplification level-notifying means 5.
