AOG, explained:
when an aircraft waits.
Aircraft on Ground is aviation's loudest alarm — a grounded aircraft with passengers, crew and schedules stacking up behind one missing part.
What AOG actually means
AOG — Aircraft on Ground — is the aviation industry's highest-priority status. It means an aircraft cannot fly until a specific part, tool or document reaches it, and every hour it sits still costs the operator dearly: missed rotations, displaced crews, rebooked passengers and knock-on delays that ripple through a whole schedule.
Because the cost of waiting dwarfs the cost of moving, AOG logistics works differently from ordinary freight. There is no consolidation, no depot and no next-scheduled-run — the part travels the moment it is released, on whatever routing gets it to the aircraft soonest.
How an AOG part moves
A typical AOG run starts at a stores, supplier or MRO facility, where the part is released with its paperwork — often including certification documents that must stay with it. A dedicated vehicle collects immediately and drives direct to the airport, the maintenance base or, where arranged, the stand itself.
Chain of custody is everything. One driver holds the consignment from release to handover, documents each transfer, and the receiving engineer signs for exactly what was released. That unbroken chain is what lets an operator trust the part that arrives is the part that left.
What separates AOG from a fast van
Speed matters, but AOG work is really about certainty and accountability. The differences that count:
- Immediate dispatch, at any hour — AOG does not wait for office hours
- A dedicated vehicle carrying the AOG consignment alone
- Documented chain of custody from release to the receiving engineer
- Drivers who understand airport processes and where handovers actually happen
- A desk that keeps the operator informed at every stage
A courier who treats an AOG job like a parcel run will lose time at exactly the moments that matter — at release, at the gate and at handover.
Booking an AOG response
When an aircraft is down, the booking conversation is short: what the part is, where it is released, which airport or base it must reach, and any reference the receiving team needs quoted. From there a dedicated driver is dispatched immediately, with the desk reporting progress until the part is signed for. If you operate or maintain aircraft, it pays to have that number saved before you need it — our AOG courier service runs 24/7/365.
