The only time you can log p1s is a sucessful flight test with an examiner. Your situation is put in uk parlance and dual in faa land, and nothing to stop you writing up your logbook in that fashion, but like I said, you may find the instructor reluctant to countersign it. As far as he is concerned its logged as sightseeing. You arent qualified because, as you say, your licence is a uk nppl, so there is no way to log it as p1(Uk) or pic(FAA), if you need the instructor then its put, cant see any interpretatation that works any other way in that situation, sorry. But what does that matter, if you dont need to use the hours anyhow, write them up as dual, and go and enjoy yourself. Opa locka is a good place to visit, also, try tamiami, winter haven, venice, I also enjoyed going to Arcadia, a one horse airport if ever there was one. If you enjoy a workout, try going to Sarasota when they are busy. Hope you have fun...
