The Future Airspace Strategy (FAS) has been developed by the Civil Aviation Authority (CAA), with contributions from the Department for Transport (DfT), Ministry of Defence (MoD) and NATS. FAS also relies on funding and a joined up approach from a variety of stakeholders. These include airport air navigation service providers, airports, airlines, general aviation partners and the military.
If you have a question about FAS then you should direct it to the relevant partners whose logos can be found at the bottom of each page of this site. Clicking on the logo will take you to their website and their contact details.
