LUN3573.02 - Aircraft intercom
LUN3573.02 aircraft intercom is electronic device designed for two-seat versions of jets where it transfers AF signals from two radiocommunication stations, warnings and signals from radionavigation and other special devices in jets to pilot's earphones, and it also distributes modulation signal to two radiocommunication stations. It also provides a communication line between the pilots and between the pilots and ground personnel.
