The FAA is preparing publication of the first LPV (lateral precision with vertical guidance) approaches, a new type of precision approach procedure designed specifically for WAAS. The hallmarks of LPV are lower landing minimums than Lnav/Vnav (250 ft and three-quarters of a mile visibility) and signals that are compatible only with IFR-approved WAAS receivers.

The Wide Area Augmentation System (WAAS) successfully passed a critical 60-day test that prime contractor Raytheon said proves the reliability of the signals for ILS-like approach procedures to thousands of airports not served by precision instrument approaches.

In presenting its 2007 technical achievement award to senior engineer Steve Lindsey for his involvement in developing a flight management system for general aviation, Avidyne has allowed a sneak peek at the heart of the company’s next-generation integrated avionics system, dubbed “Entegra Plus” by some in the industry.

Universal Avionics last month said it received an STC allowing installations of the company’s line of WAAS-capable FMS units in the Bombardier Challenger 600, 601 and 601-3R. Universal’s line of WAAS-ready flight management systems includes the UNS-1Lw, UNS-1Ew, UNS-1Espw and UNS-1Fw.

The FAA is proposing numerous revisions to instrument flight rules and procedures to reflect technological advances intended to “facilitate the transition from ground-based navigation to new reference sources,” principally GPS and enhanced vision systems. The notice of proposed rulemaking (NPRM) cuts a 60-page swath through the Federal Register, affecting Parts 1, 71, 91, 95, 97, 121, 125, 129 and 135.

The woes experienced by builders of the wide-area augmentation system (WAAS) are nothing new to those who have followed the development of the satellite-navigation project over the last decade. In fact, it has become almost cliché to use woe and WAAS in the same sentence. So it’s not surprising to learn that a program one senator once referred to as a “$4 billion boondoggle” has lost luster over time.

Premier/West Star announced the completion of its first installation of the Rockwell Collins Pro Line 21 avionics system in a Falcon 50. The package includes a new digital autopilot, dual AHRS sensors, weather radar and radio stack.

The FAA’s announcement last month that its GPS wide area augmentation system (WAAS) will support ILS-like 200-foot Category I approaches marks the agency’s third swing at this, the system’s Holy Grail. When WAAS was launched in 1995, Category I was promised by 1997, but the system’s rocky progress over the following years consigned Category I to the benches.
