The CAA have today published CAP722F, the annex to CAP722 specific to model flying. Please see https://publicapps.caa.co.uk/modalapplication.aspx?appid=11&mode=detail&id=10792 for further details.
CAP722F describes the how the current regulatory framework applies to the operation of model aircraft, sets out CAA policy for model aircraft operations, describes the boundaries between operations which require an authorisation and those that do not and provides guidance to model aircraft associations when applying for an Article 16 authorisation on behalf of their members.
Unlike CAP658 which was withdrawn in January, CAP722F is not intended to provide operational guidance on the flying of model aircraft. The CAA's view is that operational guidance should be contained within model aircraft association handbooks and other such documentation.
