The operating scenario
A communications interruption delays a ground command. When it arrives, the aircraft must establish whether the action is still authorised for that aircraft and under the applicable conditions. Delay alone does not make a command invalid.
The proposed authority boundary
Evaluate the target aircraft, requested operation, authority scope, validity and available evidence before accepting a controlled command. Weaker connectivity must not enlarge the authority that the aircraft can establish locally.
What the partner evaluates
- A legitimate command within current authority can be accepted.
- An expired, mis-targeted or out-of-scope command is refused.
- A repeated delivery does not cause an unauthorised duplicate effect.
- Restart, state continuity and link recovery behave as specified on the target configuration.
Platform responsibilities
The aircraft retains responsibility for stabilisation, navigation and pre-authorised contingency behaviour. Acceptance checks require integration with the flight-control architecture. Flight performance, safety and airworthiness require their own validation.
An application and evaluation scenario. No flight demonstration or qualified airborne implementation is claimed.
