What is AOG (Aircraft on Ground)?
AOG (Aircraft on Ground) is an emergency logistics situation where an aircraft is unable to fly due to a missing or faulty component, requiring urgent parts delivery to restore operational status. In the UK aviation industry, AOG calls trigger time-critical courier operations with zero tolerance for delay, often costing operators thousands of pounds per hour of downtime.
What exactly is AOG (Aircraft on Ground)?
AOG stands for Aircraft on Ground — a critical situation in aviation logistics where a commercial or private aircraft is unable to operate due to a mechanical failure, missing part, or engineering issue. The aircraft is literally grounded, unable to depart its scheduled route, and every minute of delay impacts airline operations, passenger schedules, crew logistics, and revenue. AOG situations trigger emergency procurement and courier protocols, where specialist logistics providers dispatch urgent parts, components, or equipment to the airport to restore the aircraft to airworthy status.
The term is universally recognised across aviation: from major carriers like British Airways and Ryanair operating from Heathrow, Gatwick, and Luton, to smaller operators at regional airports across the UK. AOG is not a minor inconvenience — it is an operational crisis that demands immediate action.
How does AOG work in UK aviation logistics?
When an AOG situation occurs, the aircraft operator or maintenance team immediately identifies the required part or component and contacts specialist AOG logistics providers like T&C Logistics with precise specifications of what is needed, where to collect it from, and where it must be delivered to one of the UK's 14 major airports: Heathrow, Gatwick, Stansted, Luton, Manchester, Birmingham, East Midlands, Liverpool, Newcastle, Glasgow, Edinburgh, Belfast, Bristol, or Southampton.
T&C Logistics operates 24/7 AOG dispatch capability, meaning we can receive an AOG call at 02:00 on a Saturday morning and have a courier collecting parts from a supplier in central London or the Midlands within 30–60 minutes. Our fleet includes temperature-controlled vehicles for sensitive components, GPS-tracked vans for real-time visibility, and drivers trained in aviation security protocols (including cargo handler collection where required). The entire operation is coordinated by our dispatch team to ensure the shortest possible transit time to the aircraft.
Why does AOG matter and what is the cost of delay?
Aircraft downtime is extraordinarily expensive, with grounded aircraft incurring substantial costs in lost revenue, crew expenses, passenger compensation, and operational disruption, making AOG logistics a premium, time-critical service with dedicated resources.
"AOG is the most time-sensitive logistics challenge in UK aviation. A single hour of delay cascades through an entire airline's network. We've built our 24/7 dispatch capability specifically to handle these emergencies — our team understands that every minute counts when an aircraft is on the ground." — Taras, Founder, T&C Logistics
Because the stakes are so high, AOG couriers operate under strict service levels: guaranteed collection within one hour, direct routing with no intermediate stops, dedicated vehicle assignment, and real-time tracking from pickup to delivery. T&C Logistics maintains this standard across all UK airports and major industrial hubs where aircraft parts are sourced.
What are practical examples of AOG situations?
Real-world AOG scenarios demonstrate the critical need for rapid logistics response and the impact of efficient courier dispatch on aircraft availability and airline operations.
Example 1: Engine Component Failure. A Ryanair aircraft at Luton experiences an engine warning light during pre-flight checks. The maintenance team diagnoses a faulty fuel pump (part number available from supplier in Coventry, 45 miles away). At 07:15, they call T&C Logistics. Our team collects the pump at 07:48, reaches Luton by 08:35, and the component is fitted within 10 minutes. Total downtime: ~90 minutes. Without AOG logistics, the aircraft would have been delayed 4+ hours waiting for parts delivery.
Example 2: Avionics Replacement. A British Airways aircraft at Heathrow requires an avionics unit replacement. The part is held at a supplier in Slough (20 miles from Heathrow). An AOG call is placed at 14:30. T&C Logistics collects at 14:58, delivers to the aircraft stand at 15:22. Engineering team installs the unit during a scheduled maintenance window. The aircraft departs only 45 minutes late instead of a planned 6-hour delay.
What are related terms used in AOG and aviation logistics?
Understanding key terminology helps clarify how AOG support fits within the broader aviation supply chain and logistics framework.
AOG Support: Specialist courier and logistics services designed specifically for aircraft emergency situations, typically available 24/7 with guaranteed rapid response times.
Aviation Supply Chain: The network of suppliers, engineers, warehouses, and logistics providers that support aircraft maintenance and repair operations.
Temperature-Controlled Delivery: Essential for AOG situations involving sensitive avionics, hydraulic components, or electronics that must be transported in controlled environments to prevent damage.
Cargo handler collection: Authority to drive or deliver cargo directly to aircraft parking stands (aprons) at commercial airports — a specialist capability T&C Logistics maintains across major UK airports.

- What does AOG stand for?
- AOG stands for Aircraft on Ground — an emergency situation where a commercial or private aircraft is grounded and unable to fly due to a mechanical failure, missing part, or engineering defect. AOG situations require immediate logistics support to supply urgent parts or components.
- How quickly can T&C Logistics respond to an AOG call?
- T&C Logistics operates 24/7 AOG dispatch with guaranteed collections within 30–60 minutes of your call. Our team is trained to handle urgent aviation logistics at all 14 major UK airports, including Heathrow, Gatwick, Luton, Manchester, and regional hubs.
- Why is AOG logistics so expensive?
- AOG logistics commands premium pricing because aircraft downtime costs operators £8,000–£12,000+ per hour in lost revenue and operational disruption. The time-critical nature, 24/7 availability, dedicated vehicle assignment, and specialised handling required justify higher courier costs than standard delivery services.
- Can T&C Logistics deliver to aircraft stands (aprons)?
- Yes — T&C Logistics coordinates with authorised cargo handlers at each terminalraft parking stands. This capability eliminates the delay of ground-side handover and significantly reduces total AOG resolution time.
- What types of parts does T&C Logistics transport for AOG situations?
- We transport all aviation components — avionics units, engine parts, hydraulic components, electrical systems, cabin equipment, and time-sensitive electronics. Our vehicles include temperature-controlled options for temperature-sensitive components and specialised handling for fragile or hazardous materials.
