The FAA’s original plan to transition to sole-means GPS is no longer practical and some form of backup will be required for the foreseeable future, according to speakers at a recent Navigation Industry Day. This event was sponsored by the DOT, FAA and Civil Aviation Advanced Systems Development (CAASD), which is a component of the federally-funded MITRE research and development center and a key FAA think-tank resource.

Garmin has tossed its hat into the terrain awareness and warning system (TAWS) ring, announcing at EAA’s AirVenture in Oshkosh, Wis., last month that a class-B product is in the works and will be offered to buyers of Garmin 500-series avionics “within a year.”
The Department of Defense is conducting more GPS interference tests in the western U.S. through next month that will cause GPS navigation to be unreliable at times near the test centers, reported AOPA. The areas affected center on the Bonneville (BVL) Vortac in Utah, Truth or Consequences (TCS) Vortac in New Mexico and Sierra Vista Municipal Airport in Arizona.
Avidyne unveiled its Entegra FMS900W WAAS-enabled GPS navcom flight management system last month at the Sun ’n’ Fly-In in Lakeland, Fla. The FMS announcement is significant, since the system is the central computer–not to mention the user interface and input device–for Avidyne’s next-generation integrated avionics system. It is also the first of “four major announcements” that the Lincoln, Mass.
Eclipse Aviation is expecting to achieve two major certification goals–flight-into-known-icing and EASA certification–for the EA-500 very light jet by July, according to Mike McConnell, vice president of sales and marketing. Full avionics functionality should follow by year-end, aided by Eclipse’s choice to install dual Garmin GPS 400W WAAS-certified moving-map GPS navigators to provide missing GPS functionality.
Goers and GOTS describe two critical FAA programs planned for later this year and early next year, respectively. Goers stands for GPS outage en route simulation, while GOTS is similar, but with terminal replacing en route.
Speakers from Eurocontrol and the European Space Agency last month informed attendees at a meeting of the FAA’s Satellite Operational Implementation Team (SOIT) that their organizations would accept liability for system failures when the Galileo satnav system was used in critical applications requiring high-accuracy guidance, such as approach and landing operations.
Eclipse Aviation this afternoon revealed another major change to the Avio NG avionics suite for the Eclipse 500, announcing the addition of two panel-mount, WAAS-capable Garmin GPS 400W receivers to bring GPS navigation capability to the very light jet. Certification of the upgrade for Avio NG system, itself an upgrade from the original Avio avionics, is expected by June, with production cut-in planned for the third quarter.
Through its JetPlan flight planning service, Jeppesen for the last couple of years has been offering RAIM (receiver autonomous integrity monitoring) prediction reports to customers who use its JetPlan flight planning service. The Colorado firm is reminding pilots who use GPS Rnav for primary navigation about a new U.S. requirement for such reporting that went into effect on March 31.
The General Aviation Manufacturers Association expressed “grave concern” about the Federal Communications Commission’s decision last month authorizing operation of certain types of products to incorporate ultra-wideband (UWB) technology. UWB devices, such as automotive radar and communications systems, would be authorized to operate in the same frequency spectrum used for GPS navigation.
