Abstract
This invention relates to a method for implementing the air traffic service unit (ATSU) managing the links between certain aircraft equipment and the ground/board communication means, and its operating system (OS) managing input/output, the use of software and hardware resources, chaining and timing of applications that are programs carrying out aircraft system functionalities, and wherein memory partitioning mechanisms and CPU partitioning mechanisms are used; wherein operating system calls are filtered so as to prevent said AOC (Airline Operational Communication) type applications from distributing the operation of said air traffic service unit.
Claims4
A method for implementing an air traffic service unit including an operating system having an input/output management, a hardware resource, and a software resource, comprising the steps of:
- managing links between aircraft equipment and a ground/board communication means via the operating system;
- chaining an airline operational communication (AOC) application wherein the application performs an aircraft system functionality;
- timing the AOC application;
- using a memory partitioning mechanism to provide a protection check wherein the protection check determines code access of the AOC application;
- using a processing unit partitioning mechanism to assign a job a priority wherein the job priority determines CPU access of the AOC application;
- and
- filtering an operating system call from the AOC application to prevent said AOC application from disturbing an operation of said air traffic service unit.
