Can Tweaking Plane Routes Cut Aviation’s Climate Impact? An Airspace-Wide Contrail Trial Will Test…
Operation Blue Skies, a UK-backed trial, will test AI-guided flight rerouting to avoid climate-warming contrails over the Shanwick Oceanic Control Area over two winters. Part-funded by the UK Department for Transport, the £5 million trial uses AI contrail forecasts from Google and others. Modelling suggests altitude adjustments of up to 2,000 feet could cut contrail formation by 60-70% for only ~1% more fuel burn. Contrails account for about one-third of aviation's climate impact.
Impact and considerations
The trial could provide a low-cost, high-value emissions reduction lever for aviation, impacting route planning and operational costs.
Key points
- Operation Blue Skies will test contrail avoidance in the Shanwick Oceanic Control Area.
- The trial costs £5 million, part-funded by the UK Department for Transport.
- AI modelling suggests altitude adjustments of up to 2,000 feet could cut contrail formation by 60-70%.
- Contrails account for about one-third of aviation's climate impact.
- Results will be verified by Imperial College London and the University of Cambridge.
