How close is close enough? 10 ft? 100 ft? 1/4 mile? 30 degrees

30 degrees at 20 miles translates to about 10 miles off the extended
centerline. That would be wide by a space larger than the entire
control zone. 30 degrees at 5 miles is 2.5, which is wider than the
entire typical VFR circuit. Does this basic trigonometry help put your
error into perspective?
