ATC separate VFR traffic!
A colleague of mine happened to be called by a particular ATSU via telephone regarding a flight he commanded at a particular regional UK airport.
In short, the controller insisted that even though a flight was operating under VFR rules within Category 'D' airspace, the controller was responsible for separating him from IFR flights. The commander correctly pointed out that the pilot of a VFR flight is responsible for separation provided traffic information is issued in good time and refered to the Air Naviagtion Order.
After this telephone call the Air Naviagtion Order was checked and the commander's understanding was entirely correct. Therefore, if ATC are using one rule book and pilots are using another this might present with an impact on flight safety, so who is correct?
I leave this to all you pleasant people in Towers around the UK to respond.
