ARINC 653

Definition

ARINC 653 specifies an APEX API for integrated modular avionics (IMA), allowing safety-critical and non-critical software partitions to share a single processor with deterministic time and memory isolation. It is foundational to most modern fighter, transport, and CCA flight software stacks and underpins FACE conformance for many components.
