Hold on a second : Under FAR 61.51, if the safety pilot is a required crewmember, and he is responsible for the safety of flight, he does log PIC time. The example that springs to mind is the safety pilot when the pilot in the left hand seat is doing instrument approaches or holds under the hood.
If the poster has said it was a FAA question you would be correct.
As I am pretty certain this will be couple fo EASA PPL's doing the trip its not going to change things.
