GM Guidance material

## GM1 ATS.TR.250(a) Essential traffic and essential local traffic information

ESSENTIAL TRAFFIC INFORMATION — CONTENT

Subject to provisions in point (b) of ATS.TR.210, air traffic control units are required to provide separation between IFR flights in airspace classes A to E, and between IFR and VFR flights in classes B and C. Air traffic control units are not required to provide separation between VFR flights, except within airspace class B. Therefore, IFR or VFR flights may constitute essential traffic to IFR traffic, and IFR flights may constitute essential traffic to VFR traffic. However, a VFR flight would not constitute essential traffic to other VFR flights except within class B airspace.
