Hummh... We all have these radios that tune the
118-137 MHz AM aircraft band...  But what channels
are available to communicate plane to plane or
plane to ground?

Our aerospace department has a plane they fly
occasionally for flight studies.  What channel 
can I talk to them on to coordinate some GPS
experiements for example?  (That isnt too 
crowded)

Here is the list I got on the web, I'm hoping
someone private pilots out there have made
ssense of all of this an can cut to the chase...
