All the data we need should be in the FAA ATA-100 collection.

Flights will mostly be along airways.

Preferred routes should be used when possible.
http://aviationtoolbox.org/old/ATA-1...ats/Pfr_rf.txt
Transitions between airports and airways will be handled with
standard arrival and departure procedures when possible.

Excuse my ignorance, but what is http://aviationtoolbox.org ?

Lots of good data there but not so much as a readme to explain who/why. I
recently bought a copy of the FAA database disc from ATA-100 in order to play
with my own flight planning application -- now it appears that I could have
downloaded it from http://aviationtoolbox.org. Cool.
