Dangrenade: hiring a JetRanger on a PPL just requires a type conversion, which is 5 hours plus a flight test. But for insurance reasons, I needed to have 20 hours with a safety pilot (my instructor). As soon as I'd done those 20 hours, I was able to take the JetRanger solo. In fact, this was 20 hours "turbine time", my time's split between the JetRanger and the H500 (5 hours minimum on each though for the type conversions) with a bias towards the JetRanger. As soon as I'd clocked up 20 hours total, I took the H500 and the JetRanger up in the same weekend, around Snowdonia (we were doing a mountain flying course). Also, for that first solo flight in the JetRanger I took a pax up who's first flight it was in a helicopter.
