The 50nm rule does not apply to the ATP rating. Hell, I've read that you don't even need to LAND for it to be logged at XC per ATP.
Legally, I know it can be logged. No doubt... any flight to another airport can be logged as XC, regardless of what rating you're going after. However, it'll only apply to certain ratings if its over 50nm. If I fly to an airport that's 7 miles away, I can log that as XC, and it's applicable towards the ATP rating, but not towards PPC. I guess my question is more towards morality. I just don't know if that would raise any eyebrows with a potential employer, logging 6 hours or so XC for an airport that's only 40 miles away... Obviously I didn't go straight there and back. I flew grid patterns for 5 hours and only landed there for fuel. Not exactly "cross-country" in my eyes. But technically, it's loggable. I just don't want to look like an idiot if I were to get called out on it.
