New ATSIN is good - and sensible news.
However, note my capitals:
*****************
ATC and FIS Providers SHOULD not offer a service within a NFZ unless the pilot is
operating under VFR and the aircraft is a glider, balloon or piston powered aircraft
1
and not operating for the purpose of public transport.
This restriction does not apply
to operational emergency services flights (e.g. Air Ambulance).
ATC and FIS Providers MAY also provide a service to an aircraft in the above
categories within controlled airspace that is:
operating under VFR within Class D airspace; operating under Special VFR in other controlled airspace provided that it is the
only aircraft in that airspace block.
*************
Shame that it is not SHOULD in both cases.
We'll have to see what happens the next time. Will NATS use MAY to decline the offering of such services?
