Like you've ever been 600 feet from an aircraft in flight.

Not necessary, as the limits are imposed by human physiology. At 600
feet, you can resolve separations of about 1 inch in perfect
conditions with perfect vision. That makes it very hard to make out
the tail number of an aircraft 600 feet away, especially in less than
perfect conditions from a moving aircraft with a moving target.


The tail number has to be 12 inches unless its a very old aircraft which
hasn't been repainted in many, many years. Wrong again Anthony. You don't
know **** from shinola.
