This Order amends the Air Navigation Order 2016 (S.I. 2016/765) (“the 2016 Order”) to extend the flight restriction zone at and around protected aerodromes, within which flights by small unmanned aircraft must not take place without permission. “Small unmanned aircraft” is defined in Schedule 1 to the 2016 Order and covers unmanned aircraft, other than balloons or kites, of 20kg or less. The new restrictions affect both the “SUA operator” and “remote pilot” of the small unmanned aircraft, which are defined in article 94G of the 2016 Order.
