Abstract: The invention relates to an aircraft data transmission system for transmitting data between the aircraft and a transmission station located outside thereof. The inventive system includes a transmitting/receiving device for transmitting and receiving data messaged from the outside of the aircraft, a message managing device comprising a device for carrying out the PER encoding/decoding of said messages, an interface device for displaying the incoming messages to an operator and enabling said operator to generate outgoing messages, an encoding device carrying out a function of encoding the encoding/decoding device and a recording device for recording all incoming and outgoing data messages related to an internal/external communication, which passes through the message processing device and is encoded, on a recording medium.

Abstract: The invention relates to an aircraft data transmission system for transmitting data between the aircraft and a transmission station located outside thereof. The inventive system consists of a transmitting/receiving device (3) for transmitting and receiving data messaged from the outside of the aircraft, a message managing device (6) comprising means (8) for carrying out the PER encoding/decoding of said messages, an interface means (9) for displaying the incoming messages to an operator and enabling said operator to generate outgoing messages, an encoding device (13) carrying out a function of encoding the encoding/decoding means (8) and a recording device (14) for recording all incoming and outgoing data messages related to an internal/external communication, which passes through the message processing device (6) and is encoded, on a recording medium (16).
