Anyone know where I can find a list of US airports and their lat/lon

US airports with instrument approach procedures.)

The FAA's ATA-100 data files, which are available by subscription. There's a
shadow maintained by one of our newsgroupies at
http://aviationtoolbox.org/old/ATA-100/

The file you want is apt.txt. The format is described by one of the
subscriber_file_formats/ files.

Imbedded in the apt.txt file is the information about whether the airport has
an
ILS. You'll have to find some other way of screening for other types of
instrument approaches.

That's just what I needed. Thanks!
