Only three GPS models — the Garmin 400-, 500-, and G1000-series — are legal, according to the FAA documents. 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."
Many members have removed ADF and DME navigation equipment from their aircraft because of the 1996 policy, and they will no longer have access to conventional and precision approaches where the equipment is a required element. Complicating matters further, the older GPS boxes are prohibited from flying RNAV routes and terminal RNAV procedures.
