For solo time on the PPL course, it is indeed logged P1, this contributes towards your 10 hours P1 required for grant of the license. I'm happy to be corrected if I'm wrong here by someone who knows more about this than me (someone who will probably be answering the original question - sorry andyg, can't help with your question), but any time you're in the aircraft yourself or the sole manipulator of the controls then you'll log the time P1 (of course there are other occasions for time to be logged P1 but my understanding is that for these occasions it would always be logged P1). Your school/instructor should be able to help you out with regard to filling in logbooks RowleyUK, just don't expect anybody to be around when it comes to counting it up!
