✈️UK Backs £2.6M AI-Powered Flight Path Trial to Avoid Contrails
AI predicts contrail-free flight paths over the Atlantic
TL;DR
The UK government is funding a £2.6M project using Met Office forecasts and Google's AI to suggest alternative flight paths that avoid persistent contrails, aiming to reduce aviation's non-CO2 contributions to climate change.
The UK government has launched a £2.6 million trial combining Met Office weather forecasts with Google’s artificial intelligence to predict where persistent contrails will form over the North Atlantic and suggest alternative flight paths. This project aims to mitigate one of aviation's significant non-CO2 impacts on the climate by identifying contrail-friendly conditions accurately enough for aircraft to fly above, below, or around them. The trial involves two winters (2026-27 and 2027-28) with flight tests and requires normal air traffic control procedures and safety checks.
Key Points
Met Office forecasts combined with Google’s AI will identify persistent contrail conditions accurately enough for alternative routes (30-month trial).
The Department for Transport is investing £2.6 million in the project, focusing on flight tests during winters of 2026-27 and 2027-28.
Changing an aircraft's route or altitude can burn additional fuel, potentially increasing CO2 emissions even as it avoids contrail formation.
The trial will assess whether avoiding persistent contrails outweighs any extra fuel burned to alter flight paths, impacting aviation’s climate footprint.
UK government is also investing £219M in sustainable aviation fuels and another £43M on electric and hydrogen-powered aircraft technologies.
Why It Matters
If successful, this trial could significantly reduce the non-CO2 contributions of aviation to climate change by avoiding persistent contrails. However, it requires careful balancing of fuel consumption versus environmental benefits for each flight path alteration.
