If asked today for their views about automatic dependent surveillance-broadcast (ADS-B), many pilots might respond that it was developed to meet the unique needs of single-engine commercial operators in remote areas such as Alaska, where only minimal ATC services were available. Alternatively, it was aimed at helping freighter pilots best position themselves in inbound traffic streams during “rush hour” operations around freight hubs.
Sensis is building on its experience of automatic dependent surveillance-broadcast (ADS-B) in the FAA-sponsored Capstone trials in Alaska and the increasing use of its multilateration technology with the development of a 1,090-MHz receiver that is under consideration for deployment on the U.S. East Coast and preparations to deploy a multilateration system at Juneau, Alaska.
Growing numbers of smaller aircraft are compounding the problems air navigation service providers face, senior officials told the Jane’s conference at last month’s ATC Maastricht 2005.
Germany’s air navigation service provider (ANSP), Deutsche Flugsicherung (DFS), is working toward the national implementation of differential GPS-based precision approaches in a program expected to last about two years.
The FAA has implemented performance- based navigation in the form of standard instrument departures (SIDs), en route Q and T routes, standard arrival routes (Stars) and RNP special and Rnav approaches.
Performance-based navigation was identified in ICAO’s Future Air Navigation System concept of the early 1990s, which defined required navigation performance capability as a parameter “describing lateral deviations from assigned or selected track as well as along-track position-fixing accuracy on the basis of an appropriate containment level.”
Airservices Australia CEO Greg Russell made the trip to Maastricht to sign a partnership agreement with Francesco Violante, his counterpart at datalink service provider SITA, that will see the two organizations jointly support a trial in Indonesian airspace of an ADS-B network that could be a prelude to a proposed southeast Asia-wide surveillance net.
