Designed to support a rapidly evolving aviation landscape, from traditional crewed aircraft to emerging spaceport operations, MAVIS marks the most significant modernisation of the UK’s regulated aviation weather services in more than two decades. It brings together multiple legacy platforms into a single, intuitive interface.  

Developed in close collaboration with the Civil Aviation Authority (CAA) and the wider aviation community, MAVIS is now in fully-operational Beta phase with functionality continually being introduced. MAVIS replaces the longstanding Aviation Briefing Service, Network Weather Resilience, HeliBrief®, and OpenRunway™, consolidating them into one cohesive service.  

Powered by the Met Office’s state-of-the-art cloud-based supercomputing capability, MAVIS provides faster, clearer and more accessible meteorological data, including Meteorological Aerodrome Reports (METARs), Terminal Aerodrome Forecasts (TAFs), UK charts and interactive map layers, supporting safer decision making across the aviation sector. 

A platform designed for a changing aviation landscape 

MAVIS has been shaped through extensive user research and feedback from airlines, airports, pilots, emergency responders, offshore helicopter operators, balloonists, and the general aviation community, ensuring it reflects the needs of the entire sector.  

Its launch supports the Met Office’s long-term commitment to helping the aviation industry operate safely and efficiently amid the challenges of climate induced hazards.  

Lauren Donohue, Aviation Business Manager at the Met Office, said: “The official launch of MAVIS represents a major milestone in how we support aviation in an evolving climate. By bringing all our regulated aviation services together into a single platform, we are enabling faster, more intuitive access to the data aviation professionals depend on. 

“MAVIS will play a central role in supporting the future of aviation with world-leading science, clear insight and user-driven innovation, especially as weather patterns shift and our climate evolves, making operations more complex. MAVIS is designed to adapt, ensuring the UK’s weather intelligence keeps pace with the next generation of aviation.” 

Continuity for regulated users, and new capabilities for the future 

As the UK’s National Meteorological Service, the Met Office provides safety critical weather services for aviation on behalf of the Civil Aviation Authority. The Met Office will continue to deliver all-regulated aviation weather services via MAVIS at no cost to UK users.  

For organisations that need more advanced functionality, a range of optional commercial upgrades including tailored forecasting and enhanced interactive visualisation tools, are available to support more complex operational decisions. 

A collaborative milestone for UK aviation 

The launch of MAVIS is part of the wider CAA regulated modernisation of UK aviation meteorology. 

Darren Hardy, MET Technical Officer, Airspace, Air Traffic Management and Aerodromes for the Civil Aviation Authority said: “We welcome the official launch of MAVIS, which represents an important step forward in the modernisation of the UK’s regulated aviation weather services. By consolidating multiple longstanding platforms into a single, resilient and user-focused system, MAVIS will help ensure that pilots, operators and air traffic teams have access to consistent, high quality meteorological information that supports safety across the aviation network.”   

Supporting transition across the aviation sector 

Legacy aviation services (except Network Weather Resilience (NWR) will be retired on March 24, 2026. NWR will be retired at a later date. 

A range of support materials for MAVIS, including explainer videos, guidance, FAQs and updates, are available online to help users get started with the new platform. MAVIS will continue to evolve to meet the needs of the aviation sector.
