I found another cool web resource today:

http://www.fly.faa.gov/Products/Coded_Departure_Routes/NFDC_Preferred_Rou
tes_Database/nfdc_preferred_routes_database.html

It's the database of IFR preferred routes. There's a fairly basic
search page, or you can just download the whole thing as one big text
file. Yet another reason to not bother buying the AFD :-)

Anybody know what "Route Type: L, H, LSD, HSD, SLD, HLD, TEC" means?
TEC is obviously Tower Enroute Control, and I'm guessing L and H are Low
and High (presumably above and below 18000), but what are the others?

Here you go:

CODE DESCRIPTION
---- -------------------------------

L LOW ALTITUDE
H HIGH ALTITUDE
LSD LOW ALT SINGLE DIR
HSD HIGH ALT SINGLE DIR
SLD SPECIAL LOW ALT DIRECTIONAL
SHD SPECIAL HIGH ALT DIRECTIONAL
TEC TOWER ENROUTE CONTROL

This is cool. Anyone know of an online repository for the trunc routes
heading to the NAT entry points?
