1. A system to send air traffic control (ATC) data-link messages from an aircraft, the system comprising:
- a communication manager in the aircraft having two data link addresses for the aircraft, the communication manager comprising;
a first copy of software in a first data link layer portion assigned a first one of the two data link addresses and configured to communicate ATC data-link messages; and
a second copy of the software in a second data link layer portion assigned a second one of the two data link addresses and configured to communicate non-ATC data-link messages,wherein the aircraft is configured to execute ATC applications in a first portion of an application layer onboard the aircraft, and wherein the aircraft is configured to execute non-ATC applications in a second portion of the application layer onboard the aircraft, andwherein the ATC data-link messages are sent from the aircraft independent of the non-ATC data-link messages sent from the aircraft via a physical link between the communication manager and an aircraft radio.

Abstract
A system to send air traffic control (ATC) data-link messages from an aircraft is provided. The system includes ATC applications in a first portion of an application layer, non-ATC applications in a second portion of the application layer; and a communication manager in the aircraft having two addresses for the aircraft. The communication manager includes a first copy of software in a first data link layer and a second copy of the software in a second data link layer. ATC data-link messages are sent from the aircraft independent of non-ATC data-link messages sent from the aircraft.

10. A method to send air traffic control (ATC) data-link messages from an aircraft independent of aeronautical operational control (AOC) data-link messages sent from the same aircraft, the method comprising:
-
providing a first data link address and a second data link address for the aircraft to a ground station communicatively coupled to the aircraft; sending the ATC data-link messages from the aircraft to the ground station via a physical link between a communication manager in the aircraft and an aircraft radio using a first logical channel that is associated with the first data link address and reserved for the ATC data-link messages; and independently sending the aeronautical operational control (AOC) data-link messages from the aircraft to the ground station using a second logical channel that is associated with the second data link address and reserved for the aeronautical operational control (AOC) data-link messages. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method to send air traffic control (ATC) data-link messages from an aircraft independent of aeronautical operational control (AOC) data-link messages sent from the same aircraft, the method comprising:
-
sending the ATC data-link messages from the aircraft via a physical link between a communication manager in the aircraft and an aircraft radio by implementing a first logical channel, which is associated with a first data link address and reserved for air traffic control data-link messages, to communicatively couple the aircraft to the ground station; and independently sending the aeronautical operational control (AOC) data-link messages from the aircraft via the physical link between the communication manager in the aircraft and the aircraft radio by implementing a second logical channel, which is associated with a second data link address and reserved for non-ATC data-link messages, to communicatively couple the aircraft to the ground station. - View Dependent Claims (17, 18, 19, 20)
