Updating airline technology needed problems kids definition radiometric dating
To implement this, the Federal Aviation Administration (FAA) will undertake a wide-ranging transformation of the entire United States air transportation system. Congress established the Joint Planning and Development Office (JPDO) to plan and coordinate the development of the system.
The National Air Traffic Controllers Association (NATCA) conducted a demonstration at Dallas/Fort Worth International Airport (DFW) of a new surveillance display called the Tower Flight Data Manager (TFDM) system that would present surveillance, flight data, weather, airport configuration and other information critical to controllers. Department of Transportation Inspector General Calvin Scovel and U. Government Accountability Office Director of Civil Aviation Issues Gerald Dillingham told Congress that the FAA faced considerable challenges in implementing a satellite-based Next Gen ATC system, ranging from delays in approving new procedures and technology to skepticism among airlines regarding investment in new equipment.Next Gen proposes to transform America’s air traffic control system from a radar-based system with radio communication to a satellite-based one.GPS technology will be used to shorten routes, save time and fuel, reduce traffic delays, increase capacity, and permit controllers to monitor and manage aircraft with greater safety margins.A report released in October 2011 by the Government Accountability Office found the FAA has made some progress in implementation, but delays threaten to impact costs and benefits.Specifically, some acquisitions have been delayed, which has impacted the timelines of other dependent systems.
A feature of the Next Gen program are GPS-based waypoints, which result in similar flightpaths for planes.
