Saab will strengthen its air-traffic-management (ATM) business, adding to its portfolio a ground surveillance system deployed at major U.S. airports, with the planned acquisition of Sensis Corp., of Syracuse, N.Y. The Swedish defense and security group is to acquire Sensis for $155 million, with another $40 million based on winning future contracts and meeting profitability goals.
ITT Has Traffic Data for Commercial Customers
ITT Corp. has announced the commercial availability of real-time air traffic surveillance and tracking data, marking the first-ever sale of data collected through the automatic dependent surveillance-broadcast (ADS-B) network being deployed by ITT as part of the Federal Aviation Administration’s NextGen initiative.
For many, multilateration (sometimes abbreviated Mlat) is one of those vague ATC terms that is always hard to define. Put simply, it is how a spread-out group of small, unmanned, ground-based “listening posts” continuously monitors aircraft transponder signals, and then collectively triangulates them to derive individual aircraft positions. Following that, they send those positions plus their idents, altitudes and other data to ATC.
For years the world’s aviation authorities have been preparing for the transition to a re-imagined operating environment where an array of new technologies–placed on the ground, in space and in the cockpit–can be applied to the daunting task of funneling thousands more airplanes from departure to destination each day without encountering the choke points that inevitably would arise from using a global navigation infrastructure developed when D
Since Hank Krakowski became COO of the FAA’s Air Traffic Organization in October 2007, he has focused his attention on making the ATC system more efficient.
Researchers at Sensis’s Seagull Technology Center in Campbell, Calif., have calculated what they call excess fuel burned during taxiing at 13 of the nation’s largest airports. In this case, excess means the amount of time spent taxiing versus the ideal time required to proceed from the ramp to the takeoff point, and from exiting the runway to the ramp after landing, and then converting the time difference into fuel burn.
Everybody in aviation has heard about NextGen, the buzzterm that stands for the ponderous Next Generation Air Transportation System. But what is it, exactly? Ask 10 people and you’ll likely get 10 different answers. And don’t ask the popular media or tv or a politician: all they’ll tell you is that it’s “satellite-based” and coming soon.
A new runway and taxiway surveillance system, the Airport Movements Area Safety System (Amass), has gained the confidence of some air traffic controllers despite criticism of its performance by the NTSB. The National Air Traffic Controllers Association (Natca) recounted two incidents at Boston Logan International Airport in which Amass is credited for alerting ATC in time to prevent runway collisions.
Two recent ATC conferences underscore the various points of view about the most efficient ways to implement the next generation of air transportation, either gradually, taking advantage of today’s technology, or all at once in 2025.
Although the media and Congress continue to wring their collective hands over the rising number of reported runway incursions, the FAA is claiming that the severity of these incursions has remained relatively low and stable over the past four years.
