Bell Helicopter announced last month that its new 429 light twin has been approved for precise wide area augmentation system (Waas) glidepath operations. The capability will allow the 429 to be flown to point-in-space approaches when the cloud ceiling is as low as 250 feet agl and to conduct steep (9 degrees) localizer precision with vertical guidance (LPV) approaches at a minimum velocity for instrument approaches (Vmini) of 45 knots.
Wide Area Augmentation System
Honeywell received FAA TSO approval last month to start deliveries of an FMS software upgrade that provides advanced GPS-enabled approaches and access to Future Air Navigation System (Fans) routes in congested airspace and on oceanic airways. With the approval, Honeywell’s FMS 6.1 software upgrade can be installed in approximately 600 business aircraft equipped with the Honeywell FMZ-2000 flight-management system.
Gulfstream has received FAA approval to add Waas functionality in the G150 as part of a final-phase manufacturing installation that adds an optional Waas-capable GPS receiver to the airplane. The Waas upgrade is also available for retrofit in G150s already in service.
Hawker Beechcraft Services (HBS) has begun scheduling wide area augmentation system (Waas) upgrades on Rockwell Collins Pro Line 21-equipped King Air 200/300s. This installation follows the introduction of the King Air C90GTi upgrade announced last March. According to an HBS spokesman, the King Air 200/300 Waas upgrade offers operational flexibility and cost savings associated with direct and curved area navigation (Rnav) routes.
ARSA Cautions Clinton on Aviation Exports
Bombardier and Honeywell have received a supplemental type certificate (STC) to install Primus Elite LCD cockpit upgrades on Global series business jets. The cockpit upgrade for the Global 5000, Global Express and Global Express XRS is available as a retrofit or, on new aircraft, as an option.
Rockwell Collins has received a supplemental type certificate (STC) allowing Waas LPV upgrades in King Air models equipped with the avionics maker’s Pro Line 21 cockpit. Collins worked with Hawker Beechcraft to develop the STC, which covers the King Air C90GTi, B200, B200GT, B200C, 350 and 350C.
Cessna Aircraft last month announced the introduction of wide-area augmentation system (Waas) avionics upgrades for the Citation CJ1+, CJ2+, CJ3 and Encore+ as well as certain Citation Excel and XLS airplanes. Cessna has obtained a service bulletin for the installations in the CJ models and Encore+. Waas can be added to Excel and XLS models equipped with the Universal Avionics UNS-1Espw flight management system.
The first geostationary satellite for India’s Gagan GPS space-based augmentation system (SBAS)–essentially similar to Waas–was lost on April 15 when its launch rocket’s second-stage cryogenic engine failed to ignite. That followed the early-April loss of Intelsat’s Galaxy 15 geosat, which was carrying the FAA’s Pacific Waas transponder.

That followed the early-April loss of Intelsat’s Galaxy 15 geosat, which was carrying the FAA’s Pacific Waas transponder. The satellite was slowly drifting out of orbit and could no longer provide usable GPS accuracy corrections.
