Can I fly UK (G Reg) aircraft in the UK on an FAA/NZ/Australian/South African PPL or must I convert to a UK or EASA licence?
Until April 8th 2017, (was 2014 and subsequently 2016) providing you obey the restrictions of your licence, it is fully valid (eg: sign-offs, medical, etc), and UK Air Law and stick to a private VFR flight in UK Airspace, you do not need to convert your licence. From 8th April 2017 (was 2014 then 2016) you will be restricted to non-EASA aircraft (eg: Permit aircraft, or the small number of UK CAA CofA types) OR you could get a one-year formal validation, but that will be almost as much trouble as a conversion. Remember if you have a foreign licence (eg South African) where PPL holders must stick to their exact approved types without formal sign off by an instructor approved by that country, you must not assume that a UK instructor can alter the types you can legally fly. Usually, they cannot.
If you learned abroad, you probably need a UK instructor to brief you well on UK Air Law, and maybe to 'ride shotgun' for a couple of cross-country flights in the UK. It would be well worth looking at the
Pre- Preflight Checklist which takes you through all the legalities and tips before making a flight in the UK. If you want to convert to an EASA PPL,
see Q&A 25 below.
