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.
Wide Area Augmentation System
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.
A supplemental type certificate (STC) has been approved for Rockwell Collins to provide localizer performance with vertical guidance (LPV) upgrades for the King Air C90GTi, B200, B200GT, B200C, B200CGT, 350 and 350C. According to a Rockwell Collins spokesman, the company has worked closely with Hawker Beechcraft to develop and certify the coupled LPV solution, which includes an upgrade to a Rockwell Collins GPS-4000S.
Stevens Aviation last month said it has gained an STC for installation of Honeywell’s runway awareness and advisory system (Raas) in the Learjet 60, adding another element to a major cockpit and cabin upgrade program for the model. The Raas software is part of the airplane’s enhanced ground proximity warning system.
