Abstract: The invention relates to a communications system (10, 110) for an aircraft comprising a transceiver (22) having at least one transmitter (24), at least one receiver (26, 28) and at least one antenna, at least one data processing device (12) connected to the transceiver (22) by means of a data transfer device (20) and having at least one operating device (14), connected to the at least one data processing device (12), having manually activated switches, buttons and/or rotary knobs (18) for entering data into the at least one data processing device (12). According to the invention, the at least one operating device (14) is mechanically connected to the at least one data processing device (12) to form an assembly (16).

Abstract: A control panel for a communications system of an aircraft has at least one transmitter and at least one receiver, with multiple transmission and reception channels, and multiple operating elements that have an on/off function, in each instance. Each operating element is assigned to one of the transmission and reception channels. Reception on the transmission and reception channel, in each instance, can be released by the on/off function. A selection switch has a selection position for each transmission and reception channel, in which it releases the related transmission and reception channel for the transmission and blocks the other transmission and reception channels for transmission. The selection switch has a further selection position, in which it releases the transmission and reception channels that are released for reception by the operating elements, for transmission, and blocks the other transmission and reception channels for transmission.
