I am sitting here with my JAR-FCL and in paragraph 1.220 b) it says:
"Divisions: Type ratings for aeroplanes shall be established for:
(1) each type of multi-pilot aeroplane; or
(2) each type of single-pilot multi-engine aeroplane fitted with turbo-prop or turbojet engines; or
(3) each type of single-pilot single-engine fitted with a turbojet engine; or
(4) any other type of aeroplane if considered necessary
and I now see that you are correct..you are reffering to single-pilot single-engine turbo-prop. But what I also find is that a class rating is established for each manufacturer of single-engine turbo-prop aeroplanes..
