2. Description 2.1 General This duplex communication system (Fig. 1) is used for aircraft push-back. The tug driver, two wing walkers and marshalling agent wear headsets in conjunction with Transmitter/Receiver Units »CTGateCom II.24/Multi«. The four headset wearers outside the aircraft can communicate with one another. The tug driver is able to communicate with the flight deck via the Aircraft Interface that is connected to the aircraft intercom on the outside of the aircraft.
