Gatwick Unveils World-First Tech to Slash Delays and Carbon Emissions
Gatwick Airport has launched a game-changing aircraft separation system that promises to cut carbon emissions and boost flight punctuality. This global first replaces the old fixed-distance rule with cutting-edge, time-based intervals.
Revolutionary System Cuts Emissions and Delays
The new tech, developed by air traffic managers NATS and tech firm Leidos, slashes annual CO₂ emissions by up to 19,000 tonnes. It does this by reducing time planes spend waiting to land—especially when strong headwinds normally cause hold-ups and cancellations.
“Introducing Intelligent Approach at London Gatwick is another world first and shows the strength of our partnership with the airport,” said Chris Norsworthy, NATS Director of Airspace and Future Operations. “This will directly improve on-time performance, reduce late or cancelled flights, and cut carbon emissions.”
First Time for Single-Runway Mixed-Mode Airports
Known as Intelligent Approach, this system is the first to be used at a single-runway mixed-mode airport, where arrivals and departures share the same strip. Before Gatwick, time-based separation was only at huge airports like Heathrow, Toronto Pearson, and Amsterdam Schiphol.
Mark Johnston, Gatwick’s Chief Operating Officer, said: “This leading technology will provide more reliable landing times and reduce delays, which is great news for passengers. Crucially, it will also significantly cut aircraft fuel burn and emissions – a key priority for us.”
How Intelligent Approach Works
- Enhanced radar tools calculate perfect aircraft sequencing in real time
- Live wind data and departure clearance times factored in
- Allows continuous landings even in tricky headwinds without sacrificing safety
Graham Emmons, Leidos UK Managing Director, added: “Gatwick is the first to adopt our Advanced Mixed Mode capability. It’s a major milestone for improving operational efficiency and cutting emissions per flight.”
A Giant Leap for Green UK Aviation
The system is part of a bigger green push in UK aviation, linked to the European SESAR Programme that pioneers Time Based Separation tech. With growing pressure to clean up air travel, Gatwick could set the standard for single-runway airports around the world.
