The new integrated, regulated Met Office Aeronautical Visualisation Service (MAVIS®) is now operational, marking a significant step forward in supporting safer, smarter decision‑making.

Legacy Met Office aviation services will retire 24 March 2026. Aviation Briefing Service, HeliBrief, Network Weather Resilience and OpenRunway users should transition to MAVIS now, to maintain uninterrupted access to regulated aviation weather data.

MAVIS is evolving alongside the needs of the aviation sector. When new releases occur, you can find updates highlighted on our website along with our FAQs page which address a range of questions.

Sign up to MAVIS and access more information and updates.
