That's the point. It ain't all done in a small area in the first phase. I
went through rotary wing primary training in Ft Woters, TX myself, then
after my first tour in 'Nam, I worked there three years as a primary flight
instructor. To handle 200 or 300 primary students, a helicopter primary
school uses up a hell of a lot more airspace than is available at any post
with an active arty impact area. Got to keep'em clear of the GT line, out
of the impact area, and completely away from such things as parachute drops,
not to mention out of commercial air traffic, and seperated from each other.
Might be able to do all that if you draw a 250 - 300 mile radius around a
given place, and can control ALL the airspace from the surface upward.


I should hope you would be able to keep them separated - a cylindrical
airspace block 3 miles high and 600 miles across contains 848,230
cubic miles of airspace and then some. That comes out to 2800+ cubic
miles of airspace per student at a student load of 300, assuming one
student per aircraft. Think that's enough separation?

BTW, where in the U.S. do you think that you are going to be able to
obtain an area of low-altitude airspace that is 500-600 miles in
diameter and get full control of it? Sounds like a primary flight
instructor's wet dream but it probably ain't gonna happen.
