Can any flight be logged as PUT?
This may sound like a strange question, but I seem to recall from the dim and distant past something about flights that start and end at the same airport and don't go more than 50 miles or so being different from flights that land away.
Anyway, the reason for my question is that I have a lapsed PPL due to health and for various reasons may not bother to renew it. But I would quite like to hire a plane and instructor from time to time and go off flying somewhere - so I would be in the LH seat flying and logging it as PUT.
Can I do any flight like this, including going foreign, or are there restrictions if you are not strictly speaking 'under training' but just doing it for fun?
