Boeing’s delivery in May of a 737-800 airliner certified for the global navigation satellite landing system (GLS) marked the culmination of a 10-year development effort. It also served as a reminder that the ground-based augmentation system (GBAS) still has a future, despite a U.S.
Like the proverbial cat with nine lives, loran has once more rebounded from attempts on its life. Loran has always been owned and operated by the U.S. Coast Guard, which since the late 1990s has been trying to close down the system. Congress has consistently demurred and has each year put continuing operating funds for loran back into the agency’s budget.
The NTSB’s analysis of the Nov. 22, 2004, crash of a Business Jet Services Gulfstream III suggests that the pilots might have followed the fast/slow indicator on the left side of their EADIs instead of the glideslope on the right. On the way to pick up former President George H.W. Bush, the aircraft crashed into a light pole more than three miles southwest of Houston’s Hobby Airport while attempting to shoot the ILS Runway 4 approach.
Dramatic reductions in approach minimums at terrain-challenged airports are among the more spectacular results of applying RNP-Rnav. But more widespread benefits are promised when procedures based on the capabilities of modern aircraft supersede those that tie the airplanes to expensive ground navigational aids.
The vision of a future air navigation system developed by the International Civil Aviation Organization (ICAO) at the beginning of the 1990s has taken a long time to materialize. But the gradual execution of some of the main elements suggests the future may finally be at hand.
Owners of older Honeywell GNS-X flight management systems have until the end of the month to take advantage of special pricing on new GNS-XLS units, the maker announced here yesterday. Buyers who take advantage of the promotional offer will receive a $3,000 discount off the price of a new GNS-XLS FMS, as well as free software that introduces the latest worldwide navigation capabilities to the unit, according to the company.
The NTSB released its final report on the Nov. 22, 2004 crash of a Gulfstream III in Houston that killed three crewmembers. The jet, operated by Business Jet Services, was on its way to pick up former President George H.W. Bush. The jet struck a light pole and crashed about three miles southwest of Hobby Airport while on the ILS approach to Runway 4.
Operators using the new Rnav SID procedures at Dallas/Fort Worth and Hartsfield-Jackson Atlanta International Airports can expect a visit from their principal operations inspectors (POIs). The FAA said implementation has been a “general success,” with benefits such as greater efficiency and reduced communications.
The FAA is proposing to decommission all 54 direction finders (DF) and associated DF approaches in all states other than Alaska. “DFs have been used sparingly over the last nine years and the equipment is beyond its useful life cycle,” the agency said.
Looking ahead to technologies that likely will be commonplace in tomorrow’s business jet cockpits, Rockwell Collins has introduced a GPS receiver with WAAS (wide-area augmentation system) capability and a new traffic surveillance system that can host ADS-B (automatic dependent surveillance-broadcast) applications.
