CONSTRAINT #25 activeNetwork
Aircraft Availability & Substitution
A mission's viability is threatened when the originally sourced aircraft becomes unavailable and the substitute aircraft fails to meet the mission's performance, payload, or passenger requirements.
Decision Question
If the primary aircraft becomes unavailable, does the substitute maintain the mission envelope (range, payload, speed)?
Trigger Conditions
- • Original aircraft goes AOG
- • Operator cancels or reallocates
- • Crew availability changes
Affected Mission Layers
aircraftnetworktimingbaggage
Propagation Paths
- Aircraft AOG → Substitute sourced → Substitute lacks payload capacity → Baggage left behind
Failure Modes
- • Mission delay
- • Payload reduction
- • Forced fuel stop
- • Mission cancellation
Unknowns (Requires Confirmation)
- • Real-time operator fleet status
- • Substitute aircraft exact performance data
Recovery Dependencies
- • Operator network depth
- • Passenger payload flexibility
- • Schedule buffer
