1. When you have planes making anywhere from power off 180's to 2 and 3 mile base turns, how precise is that?
2. So rather than putting together a mental picture, you would rather put the onus on everyone else. You must work in automotive, and just push every thing off on suppliers.
3. Maybe you're on an instrument approach but haven't broke out yet and need to determine whether you can go straight in, or need to fly the pattern, maybe you're making a crosswind leg, maybe you have to go around and have to re-establish. Maybe you're on downwind, and that was 456's first call for some reason, and it's not a Cirrus but a 152. There are a bunch of reasons.
But hey, throw it on everyone else, because hey, why not, I guess. ATTITPA indeed.
