MIKECR,
I do enjoy flying as a safety pilot, it is a good experience flying a more complex machine and i am logging it as other flying.
What is getting to me is doing my normal job on the AOC then having to crew this. There are mixed feelings amongst the ranks and some think it should be counted as part of a Flight Duty Period and others do not. The other sneaky thing they like to do is tell you that the day flying as a safety pilot was a "day off"
