PSAOC
CAA are looking at producing a public services AOC to cover Police, Fire and SAR type Ops. These are all activities not covered by JAR Ops as they are not considered Commercial Air Transport, although they are Public Transport under UK legislation.
Police already operate to PT standards with easements and as far as I know there is no move affot by CAA to change the way they operate.
JAR Ops 3 defines HEMS as public transport and so won't come under the PSAOC.
Hope this helps
