"kylania; Basically you just need to patrol near that spot for X number of hours, 72 I think maybe? Once you've done that it should mark as complete."
The question is, how close do you have to stay to the patrol pinning point? I have yet to get a misssion complete in the Western Approaches. Doesn't seem to affect my play or score but it would sure be nice to complete a mission every now and then.
