Bottom line is. Your a member of a flying club and hire an aicraft.
You take a mate along who is also a pilot but not a fellow member of club.
You fly the a leg out as P1 and land. Your mate fly's back as P1 to base.
You now have to pay for the flight.
1: Do you pay for whole flight (of course you should, so know one knows what your doing)
2: Then get your mate to cough up the ready's for his flight.
3:Now its gets dodgy. You have to show your entire flight as P1 to your club.
but you and your mate have only logged and can only log the relevant P1 flight times to keep "legal" in your log books.
4: All is well until that time when ?
