Standardized inter-partition communication and deterministic execution tables for avionics modularity.
The APEX (Application Executive) interface enables software vendors to develop avionics applications that run unchanged across any certified RTOS platform, protecting aircraft OEMs from single-vendor lock-in.
AvionicsOS implements certified sampling ports for high-rate continuous telemetry (where latest values overwrite stale data) and queuing ports for sequential control commands (where message order is preserved without packet drops).
