Definition of 'Fast Moving'
Flying a Islander I was warned by the ATSU providing a RIS of 'fast moving' traffic etc. It was a pair of Canberras which I estimated at around 200 kts. Obviously a bit faster than I was doing in the Islander but lead me to wonder. Is there a diffinitive speed for issuing a 'fast moving' advisory or is it relative to the respective aircraft. (Presumably the same applies to 'Slow Moving'?
