One of the main tasks of a radar controller is ensuring separation at all times as this allows for a safe flow of traffic. We distinguish between different types of separation.
As a general rule, ATC shall provide separation between
- all flight in airspaces A and B,
- IFR flights in airspaces C, D, E,
- IFR flights and VFR flights in airspace C,
- IFR flights and SVFR flights.
