The FAA has issued a proposed plan to transition the national airspace system (NAS) to a performance-based navigation system that relies on GPS and “area navigation everywhere and required navigation performance where beneficial,” instead of defining airways, routes and procedures using VORs and other legacy navaids. A minimum operational network of VORs and an “optimized network” of DMEs would be retained, and this drawdown would be complete by Jan. 1, 2020.
Localizer Performance with Vertical guidance
New technology is finally enabling avionics manufacturers to make head-up display (HUD) systems smaller, and Rockwell Collins is first out of the gate with the new HGS-3500. While it wasn’t able to bring a working model of the device to Geneva, the company is displaying a mockup at EBACE (Stand 7036) to show the unit’s stowable capability.
Jet Aviation St. Louis (formerly Midcoast Aviation) has completed the first wide-area augmentation system (Waas) FMS installation in a Dassault Falcon 2000, and it did it under a basic FAA field approval rather than obtaining a full supplemental type certificate (STC).
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
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.
In 1994 Steve Hickok began the initial flight tests that led to development and implementation of the first FAA-approved GPS Rnav helicopter instrument approaches.
Horizon Air on December 30 became the first scheduled-service passenger carrier to operate a flight using wide area augmentation system (Waas) technology. Equipped with dual Universal Avionics UNS-1Ew flight management systems, Horizon’s only Waas-capable 76-seat Bombardier Q400 carried out the trailblazing mission on a flight from Portland to Seattle.
Universal Avionics spent much of the last year working with FAA officials trying to come up with a way to upgrade the customers’ flight management systems for Waas LPV approach capability under a basic field approval rather than having to submit to the cumbersome supplemental type certification process.
