Project: ARINC 653

Goal: Develop ARINC 653, Avionics Application Software Standard Interface, defining a standard interface between avionics application software and Real Time Operating System (RTOS).

Scope: ARINC 653, developed as three parts:

• Part 1 - Required Services
• Part 2 - Extended Services
• Part 3 - Conformity Test Specification

Benefits: ARINC 653 is used extensively on new civil aircraft and new military aircraft produced by Airbus, Boeing and Lockheed Martin. Avionics suppliers have expressed the desire to use ARINC 653 RTOS on regional, business and private aircraft. ARINC 653 enables application software to be developed concurrently and independent of the RTOS. This will enable avionics functional updates to be made with minimal impact on the underlying computing platform.
