MAVIS is Here:

Saying Goodbye to Legacy Met Office Services

[object Object]

The Met Office MAVIS (Aeronautical Visualisation Service) is now the primary regulated source for UK pilot weather. As the legacy portal retires in March 2026, ensure you are ready to use the new interactive charts and frontline weather data for your pre-flight planning.

As we approach the end of March 2026, the Met Office is officially pulling the plug on its legacy aviation weather products. The new MAVIS (Met Office Aeronautical Visualisation Service) is now the primary regulated source for UK GA pilots. If you haven't yet migrated your account or familiarized yourself with the interface, the time to do so is now.

MAVIS represents a significant leap forward in how weather data is presented. Instead of static PDF charts, the platform offers an integrated, interactive map that overlays TAFs, METARs, and SIGMETS onto a single interface. One of the most useful features for PPL holders is the "Timeline" slider, which allows you to visualise the movement of fronts and precipitation over your planned route in real-time.

While third-party apps like SkyDemon and ForeFlight remain popular, the CAA reminds pilots that MAVIS is the regulated source for UK weather. In the event of an occurrence, being able to demonstrate that you used the official Met Office service is a key part of a pilot’s legal due diligence. The transition period has seen some teething issues with "Drone Assist" app integration, but the core MAVIS platform is now stable. Ensure you have your login details ready and have practiced pulling a briefing pack before your next cross-country flight, as the old portal will be inaccessible by the end of the month.
