Everybody talking about "looking at the wings" needs to rethink their

You can see an entire airplane much farther away than you can
distinguish
the wings.

If he's so far away that you can't determine what he's doing it's likely
the other traffic isn't a factor...at least not at the speeds of most GA
aircraft.

Rely on relative motion. If the dot isn't moving relative to your
viewpoint, you're on a collision course.


Not necessarily. The dot could be moving directly away from you.

That's still a collision course. It will just take a lot longer (and a lot
more fuel) for you to eventually collide). You'll either catch up, or the
other aircraft will eventually fly all the way around the world and catch up
with you.
