Events National Air Ambulance Week 2021 National Air Ambulance Week (NAAW) takes place in the second week of September each year and it's a fantastic opportunity to give your local Air Ambulance a national united voice, to promote the hard work that goes on not only during that week, but throughout the year. Every day, Devon Air Ambulance receives fantastic support from individuals, businesses and Devon's communities. During National Air Ambulance Week (NAAW) all of the member charities of Air Ambulance Association (AAA) get together to promote the work undertaken locally, but also on a national basis. It's never too early to get involved and start organising your event for the next National Air Ambulance Week. We encourage our supporters to jump on board with fundraising events!
