1.3 Some of the following are terms used by the UK Military as defined in the Military Aviation Authority (MAA) Regulatory Publications (MRP). These terms (identified by an asterisk *) are not necessarily applicable to UAS that are subject to civil regulations.
NOTE: The terms ‘pilot’ and 'Remote Pilot' are being increasingly used worldwide (including ICAO) to describe the person who directly controls an unmanned aircraft and that trend is reflected in this document. It should be noted, however, that within the United Kingdom there are many legal requirements in the Air Navigation Order 2009 applicable to ‘pilots’. These references, however, apply only to pilots in the traditional sense – i.e. persons on board and flying the aircraft. There are at present no legal requirements setting out the qualifications needed to control an unmanned aircraft; this work is still to be completed.
