A slightly different question, and sorry in advance if it sounds a bit silly....
Can you log as P2 in a single engine aircraft, if for example, you go on a trip with a pal and you are both licensed?
When your pal acts as P1, can you log as P2 if, for example, you do the radio and do a bit of navigation, if, in one word, you just do not sit about!??.....
I have heard vaguely that it was not feasible, but I would like to get your opinion.
Cheers
