As part of its evaluation of loran as a potential backup to GPS, the FAA has contracted Rock-well Collins to build a combined GPS/loran variant of its standard multimode navigation and landing receiver. The unit’s primary function will be to provide GPS navigation, with automatic switchover to loran should GPS signals be lost or degraded, and automatic reversion to GPS when normal service resumes.

For any pilot who’s ever sat glued to the Weather Channel or logged onto a weather Web site to keep a watchful eye on a powerful cold front or line of thunderstorms sweeping across the country, the term airborne datalink could soon take on special significance.
L-3 Avionics Systems, the former Goodrich subsidiary that produces the well known Stormscope and Skywatch lines of cockpit safety systems, last month introduced a new class-B terrain awareness and warning system (TAWS) that the company said will have a list price of $12,500.
Eurocopter is making further strides toward its aim of certifying a helicopter to make IFR approaches to a hover, over a given point on the ground and at a defined height. By the end of this month, a second phase of flight tests involving a specially modified EC 155, currently under way near the OEM’s Marseille headquarters in southern France, will be complete.
LAAS could end up being overtaken by a combination of the FAA’s WAAS and Europe’s GPS equivalent, Galileo. While official speakers at last month’s U.S.
The FAA’s decision to relegate the GPS Cat 1 local-area augmentation system (LAAS) to a mere R&D program (AIN, March 2004, page 1) came as little surprise to either administration officials or industry.
Arinc has flight tested a new differential-GPS precision approach and landing system designed to withstand electronic jamming. Conducted on April 5 at Holloman Air Force Base in New Mexico in an Air Force C-12J (the military version of the Beech 1900C), the tests evaluated the performance of Arinc’s developmental local-area differential GPS (LDGPS) landing aid.
In an effort to streamline its GPS/navcom product line, Garmin will rename the CNX80 navigator the GNS 480, according to a spokesman. The new designation positions the panel-mount unit between Garmin’s GNS 430 and GNS 530 products, more than 41,000 of which are flying in various GA aircraft around the world.
Universal Avionics plans to announce FAA certification of the first TSO’d WAAS-qualified FMS for installation on Part 23 and 25 aircraft at a press conference today at
2 p.m. The new Universal W series FMS allows operators to use GPS as a primary means of navigation and to fly WAAS/LPV IFR approaches. The W series FMS is certified to TSO C146b, Class Gamma-3, according to Universal Avionics.
The FAA’s decision last month to award ITT Corp. a $1.8 billion contract (including options) to develop and deploy automatic dependent surveillance-broadcast (ADS-B) technology sets in motion a major NextGen ATC project. But it will take years for the full benefits to be realized.
