Is ILS, aviation’s trusted friend for the past half century, now seeing its last days? Probably not. Some observers believe it has many years of life ahead of it, yet newer technologies are slowly entering the scene, in such diverse settings as Norway’s fjords, Heathrow’s jam-packed runways, the icy wastes of Antarctica and at several major U.S. hubs.

At the FAA’s September International Aviation Safety Forum near Washington, the agency included a discussion session entitled “WAAS or LAAS, which is it?” An explanatory note in the agenda stated that “The FAA is investing in both, but industry experts are divided over the safety issues and benefits. What are the costs and benefits of WAAS? LAAS? Which one should we be investing in?”

While FAA Administrator Marion Blakey said required navigation performance (RNP) is receiving broad support in the U.S. and abroad, she acknowledged there is no one-size-fits-all navigation concept. The question she posed is “How do we balance finite resources in terms of WAAS/LAAS?”

The Garmin GNS 480 all-in-one GPS/navcom is now approved for primary-means WAAS navigation and localizer precision with vertical guidance (LPV) approaches. According to Garmin, pilots flying with the $11,995 unit will be able to make “ILS-like” approaches into thousands of U.S. airports not served by ILS once the FAA implements LPV procedures.

L-3 Communications Avionics Systems last month announced TSO approval for the Model 8100 terrain awareness and warning system (TAWS), clearing the way for deliveries of the $12,500 unit. The class-B system differentiates itself from other TAWS units on the market by including a remote WAAS GPS receiver, used for deriving position and altitude.

Released last month, the 2005 Federal Radionavigation Plan (FRP)–a joint production of the DOT, DOD and the Department of Homeland Security–provides a useful guide to what air navigation will be like between now and 2020. Of course, federal crystal balls occasionally can be cloudy, especially when they peer 14 years into the future.

Garmin last month said it has gained its first STC covering installation of a retrofit version of the G1000 avionics system. Approved in the King Air C90A/GT, the G1000 suite integrates primary flight information, navigation data, communications, terrain awareness, traffic, weather and engine instruments on a 15-inch-diagonal multifunction display and two 10.4-inch primary flight displays.

Garmin last week received FAA STC approval to install G1000 avionics retrofits in the Hawker Beechcraft King Air C90A/GT. The installation results in a weight saving of approximately 100 pounds. Notably, this is Garmin’s first G1000 retrofit STC, and it paves the way for future G1000 retrofit installations such as the King Air 200 and B200, a program Garmin announced in September at the NBAA Convention.

CMC Electronics showcased its new CMA-9000 flight management system (FMS), which also includes radio management. “The -9000 is a derivative of both the -3000, a helicopter cockpit product, and the airline-oriented -900,” FMS program manager Martin Richard explained. It features several search-and-rescue functions, including programmable moving waypoints.
