Method and system for automatically guiding an aircraft to a landing runway

A method for automatically guiding an aircraft to a landing runway, comprising steps implemented automatically by electronic circuitry on board the aircraft, the steps comprising:

• a first step of receiving at least one Automatic Terminal Information Service (ATIS) message;
• a second step of decoding content of the at least one ATIS message received in the first step;
• a third step, implemented in response to the decoded content of the at least one ATIS message including a parameter relating to an active landing runway, of creating a message requesting confirmation of the decoded content and commanding sending of the message over a communication frequency with air traffic control, the confirmation request message comprising at least the parameter relating to an active landing runway included in the decoded content of the at least one ATIS message;
• a fourth step of receiving a response from air traffic control to the message sent in the third step and decoding the response to determine whether or not the response is a confirmation of the decoded content of the at least one ATIS message;
• a fifth step implemented if the response is a confirmation of the decoded content of the at least one ATIS message, the fifth step comprising determination of a contingency trajectory of the aircraft at least partially in consideration of the decoded content of the at least one ATIS message;
• and
• a sixth step of automatically guiding the aircraft along the contingency trajectory determined in the fifth step.
