To make things more complicated, I went to airnav.com and looked up the distance between the two airports--it came up as 49.1 nm. What would you do? Play it safe and not count it as x/c time, or round up less than a mile and count it. I know there isnt necessarily one right answer, but im just worried bout it coming back to bite me in the ass. As always, thanks for any input!
