I have built a basic Excel which generates a flight path from all of the maps using all of the BLUE locations. If you pick a Bravo airport in a region is suggests another Bravo to fly to. If you select a Delta it suggests a Delta, Charlie or Bravo airport etc. I have also segregated the Military airports so the random generator may select a Military air field to a target military airfield.
My own primary objective is to fly out of each BLUE airport (which does not have grass) and gain experience by doing so. I was wondering if anyone else was interested?
