Avoidance Rule

[Rick Wallace]

Boy --

Personal experience says it's both division and subtraction --

Division -- this describes how the two planes re-kit each other at speed at 
altitude during a midair...

Subtraction -- describes the change in the number of available aircraft for 
both pilots....
