You know I've done this in the TA for as long as I can remember.
Up my trusty D3a1 Val, sit on the end of the runway, and keep an eye on the skys at A1 while trolling for dweebs that shoot planes on the runway.
Its the easiest way to view the whole area at one time.
Have I ever used this in the main, nope, not once as far back as I can remember.
At least not since GV's have had no external view.
Its one of those things that may not be perfect, but its the same for everyone.
