They've been slowly but surely eliminating NDBs and LOMs/OMs over the last 4 years to save money, too.

Problem for me: the T-38 GPS is not certified to be used in lieu of an OM. It should be...but the Air Force hasn't paid the money to get the TSO blessing yet.

So instead, I use a LOM with an accuracy of about 1000-2000 ft laterally, instead of the GPS/INS which is accurate to 200 ft.

Personally, I like having the old backups. I think the Feds are being penny-wise and Pound-foolish.
