Foxmoth is quite correct. If you have P1 time in your logbook on any type with a CS prop then you can fly any CS prop machine. Same goes for retractable u/c, tailwheel, turbochargers, pressurisation. If your first experience of one of these "complexities" was after 1 Jan 99 then you should have differences training signed in your logbook by an FI (although you don't legally have to fly a trip to get the training). Differences training was going to have a 2 year time period on it but this has gone and now it's for ever.
