Let's say you have your Private. You want to go flying and don't want to go alone. You call your friend up and see if he wants to come flying for a pro rata share. He agrees.
Does this count as "common purpose?"
And let's say the answer is "no, because you might of just been doing it to build flight time so you wouldn't share a common purpose." Ok. How does the FAA know/prove that your motive wasn't simply to go on a joyride with your friend who also wants to go on a joyride?
Also, how does the FAA enforce pro rata payments? Can they do some kind of audit on your expenses? Is it purely honor system along with spot enforcement (i.e. FBO reports you)?
