GWAAC was created in 2007. At launch, it operated a
Eurocopter EC135, but as flying hours increased the funding was not available, so the charity moved to a
MBB Bo 105 helicopter. In 2012, the charity started a campaign to raise the money needed to return to the EC135. The goal was reached in 2014, and in October the EC135 (registered G-GWAA) arrived at the base in
Bristol Filton Airport. The EC135 had a 40% increase in cabin volume, allowing the team to offer better inflight treatment. It had an extra seat, allowing medics to be trained on-board or a child patient to be airlifted with a parent. It can also land on elevated hospital
helipads, and allows side loading. On 1 August 2017, GWAAC upgraded to an EC135 T2+ model, registration G-GWAC, leased from
Babcock Mission Critical Services Onshore, which has more advanced features and a longer range. In 2012, it was announced that Filton airfield, where GWAAC and the
National Police Air Service (NPAS) had been based, was to close. Their landlord,
BAE Systems, agreed to find a new site and construct an airbase for the services. A site was identified in South Gloucestershire, adjacent to the
Almondsbury M4/M5 Interchange, approximately north of the Filton base. Planning permission was granted in August 2016. Work started at the site in late 2017, In July 2018, GWAAC launched a public appeal to raise funds to buy the new airbase from BAE Systems, following it being put up for sale during its construction. GWAAC raised £1.3million towards the purchase, which completed in December 2018. NPAS remain on site as tenants of GWAAC. In September 2019, the new airbase was officially opened by
Prince Richard, Duke of Gloucester. ==Operations==
