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.
