Abstract: Radiocommunication system for aircraft. The radiocommunication system (S1) comprises a single box and, integrated into this single box, at least one single main interface module (7), which is formed in such a way as to carry out the processing of the interfaces of all the radiocommunication means (3 to 6) of said radiocommunication system (S1).

Abstract: A device for inputting digital values includes a digital keyboard configured to be actuated by an operator for inputting figures of a particular digital value, display unit that displays at least the input figures, a validating unit configured to be actuated by the operator for validating a displayed digital value, and an input-aid system having an acquisition unit that acquires the input figures as they are being input and a processing unit that, knowing the digital values which are valid, determines at each input of one figure based on the valid digital values at least one auxiliary figure, which the processing unit associates with a set of already input figures to form a proposed value, and transmits the proposed value to the display unit.

Abstract: A method for the determining, on board an aircraft, of an identifier of a communications center with which an aircraft crew wishes to enter into contact, includes the following operations: a) the writing, by the crew, of a radio-communications frequency to a display unit of the cockpit of the aircraft, b) the determining of surroundings of the aircraft, c) the determining of the communications centers situated in these surroundings, d) the comparing of the frequencies of these communications centers with the frequency displayed on the display unit of the cockpit, and f) when the frequency of a communications center is identical to the displayed frequency, the display on the aircraft display unit of the identifier of said communications center having a frequency identical to the displayed frequency.

Abstract: The invention concerns a device (1) comprising a digital keyboard (2) capable of being actuated by an operator for inputting figures of a particular digital value, display means (3) for displaying at least the input figures, validating means (5) capable of being actuated by an operator for validating a displayed digital value, and an input-aid system (6) comprising acquisition means (9) for acquiring the input figures as they are being input, and processing means (10) knowing the digital values which are valid, determining at each input of one figure based on said valid digital values at least one auxiliary figure which it associates with the set of already input figures to form therewith a proposed value, and transmitting said proposed value to the display means (2) for display.
