Abstract: PURPOSE: An intercommunication device for a helicopter supporting a backup mode is provided to relay internal communications and external communications through analogue communication data by using the backup relay unit of a communication repeater even during a backup mode. CONSTITUTION: A plurality of user terminals (210, 220, 230) communicate with the inside or outside. A communication repeater (300) is connected to each user terminal. The communication repeater relays a signal from each user terminal to the inside or outside. Each of walkie-talkies (510, 520) is connected to the communication repeater, and communicates a signal from the communication repeater with the outside. An external control center (100) is wirelessly connected to the walkie-talkies, and transmits or receives a signal from or to each walkie-talkies. [Reference numerals] (100) External control center; (210) User terminal 1; (220) User terminal 2; (230) User terminal 3; (300) Communication repeater; (510) Walkie-talkie 1; (520) Walkie-talkie 2
