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).

Claims

1-6. -6. (canceled)

7. A data transmission system, which is installed on an aircraft (A) and which is intended for the transmission of data between the aircraft (A) and at least one transmission station (2) located outside of said aircraft (A) during an internal/external communication, said system (1) comprising:

a transmitting/receiving device (3) which is able to transmit outgoing data messages to outside of the aircraft (A) and to receive incoming data messages from outside of the aircraft (A), said incoming and outgoing messages which pass through said transmitting/receiving device (3) being encoded;

a message management device (6);

which is connected to said transmitting/receiving device (3);

which receives said encoded incoming messages from said transmitting/receiving device (3) and which transmits said encoded outgoing messages to said transmitting/receiving device (3); and

which comprises an encoding/decoding means (8) decoding said encoded incoming messages, in order to form decoded incoming messages, and encoding decoded outgoing messages in order to form said encoded outgoing messages;

at least one man/machine interface means (9);

which is connected to said message management device (6);

which is able to present to an operator the decoded incoming messages, which are output from said message management device (6) and which originate from said transmission station (2) located outside of said aircraft (A); and

which allows an operator to generate messages representing decoded outgoing messages, which are then transmitted to said message management device (6) and which are to be sent to said transmission station (2) located outside of said aircraft (A); and

a recording device (14),

wherein;

said encoding/decoding means (8) is formed in such a way as to carry out an encoding/decoding of the PER type;

said system (1) furthermore comprises a compression device (13) which carries out a compression for any data message;

which is not encoded,

which is relative to said internal/external communication,

which passes through said message management device (6), and

which is to be recorded;

said compression device (13) comprises at least one encoding function of said encoding/decoding means (8) which is integrated in said message management device (6) and carries out said compression in the form of an encoding of the PER type; and

said recording device (14) is connected to said encoding device (13) and is formed in such a way as to record, on at least one recording medium (16), any incoming or outgoing data message, which is relative to said internal/external communication, which passes through said message management device (6) and which is encoded according to an encoding of the PER type.

8. The system as claimed in claim 7, wherein said recording device (14) is a cockpit voice recorder of the aircraft (A).

9. The system as claimed in claim 7, wherein said encoding device (13) generates and transmits to said recording device (14) a frame comprising a frame of the PER type comprising at least one data message, together with additional information.

11. A communication assembly (17) comprising at least:

a data transmission system (1) which is installed on an aircraft (A); and

a data transmission station (2) which is located outside of the aircraft (A),

wherein said data transmission system (1) is of the type claimed in claim 7.

12. An aircraft, wherein it comprises a data transmission system (1) of the type claimed in claim 7.
