Problems solved by technology

[0016] Like all networks, it is absolutely impossible for the ATN to achieve 100% probability of delivery; but it can be achieved by eliminating the use of subnetworks of low reliability by increasing the communication capacity of the routing procedure and the transmission of subnetworks and due to this The role of redundancy included in the structure of the system makes the ATN performance close to 100% transfer

Embodiment Construction

[0078] In order to restore the functional failure of the airborne end system, the data link system of the present invention between the aircraft, such as an aircraft, and the ground includes a second airborne end system for ensuring the continuity of communication between the aircraft and the ground .

[0079] Data exchange or "crosstalk" techniques between two endpoints present the following problems.

[0080] - the data required by the first end system for the operation must be sent to the second end system before the communication can be carried out;

[0081]- All programmable controllers of the first end system contact the other controller and adopt the real-time position according to the ground-air exchange between the end users. The inputs / outputs of the individual programmable controllers located in the second end system must be downloaded to be located in advance at the time the communication takes place. However, the size of this download requires the development of...

Abstract

The data link breakdown survival technique involves the use of user interface (12) serviced by a main computer (10). The data is passed to a processor (14) by way of another interface thus giving access to an air to ground transmission transmitter-receiver link (15). There is a second spare computer (11) across the first one receiving the same information as the first computer.

Description

technical field [0001] The present invention relates to a data link system between an aircraft and at least one ground base station and a method of recovering from failure of an application computer onboard the aircraft to maintain a working link. Background technique [0002] The authorities responsible for controlling the flow of air traffic have decided to provide a standard voice communication system with digital communication means in order to maintain a good level of safety in the current situation of increased air traffic. [0003] The International Civil Aviation Organization (ICAO) is developing and implementing a global communication network called ATN for this purpose and in compliance with OSI standards. [0004] The increasing performance requirements for such data links in terms of high traffic flow and performance over normal operating hours become a major goal. [0005] Airlines currently use digital communication systems between aircraft and their operation...
