you need to be more specific about your enquiry. As another has pointed out - your shown as a UK origin but post in an Ozzy AND NEW ZEALAND forum (Mr Fanelli) so the rules may be quite different. In NZ many years ago the Group Rating prevailed which meant if you had say constant speed fixed gear - you could fly any aircraft that had that configuration but before taking pax you needed to do 3 take off and landings. All since long changed and type rating required for every different aircraft type you fly. Don't know the rules across the ditch. You need to be more specific about what you are trying to accomplish.
