When providing the service controllers issue instructions to which:
a) pilots of aircraft operating IFR are required to comply; and
b) pilots of aircraft operating Special VFR or VFR will comply unless they advise the
controller otherwise.
NOTE: The manner in which VFR flights under Radar Control Service may be safely
integrated with the IFR traffic flow in the vicinity of aerodromes is described
in Section 3.
1.3.2 Before an aircraft enters controlled airspace the controller must establish which flight
rules the pilot will be operating under.
Controlled airspace is defined as Classes A-D, Outside CAS is defined as F and G
Is there any CLASS D airspace not covered by some sort of RADAR?
