The International Cessna^® 170 Association

Many previously IFR-certified GPS receivers might now be unapproved for flying many instrument procedures due to recent FAA policy changes, according to AOPA. On Thursday, the association said the FAA's Advisory Circular 90-100A, issued in March, indicates that only three GPS models -- the Garmin 400, 500 and G1000 series -- are now legal. Other models made by Garmin, including the new GNS 480 WAAS receiver, as well as receivers manufactured by Chelton, Honeywell, Northstar, and Trimble are listed as "noncompliant," AOPA said. The action means up to 26,000 GPS users no longer comply with a 1996 FAA policy that allows GPS to be used in lieu of ADF or DME. More at:

Yes this is a mess. I'm sure they will straighten it out and have to publish a change that will cost even more money. No wonder they (FAA) thinks they need to collect more money. Can't wait to see how what they do with NEXTGEN what ever that is.
