Beags,
I notice it now says:
"Finally, in line with continued developments in UAS terminology, and the principle that unmanned aircraft are still to be treated as aircraft rather than as a separate entity, the term 'UAV' has been gradually phased out from this document and replaced with the simple term 'unmanned aircraft' (UA). In line with this, the term 'pilot' (i.e. the person who operates the controls for the aircraft) is used more frequently."
Strangely no mention of introducing the word 'drone'
