Next Generation Air Transportation System. The Next Generation Air Transportation System (Next. Gen) is a new National Airspace System due for implementation across the United States in stages between 2. 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. This transformation has the aim of reducing gridlock, both in the sky and at the airports. Congress established the Joint Planning and Development Office (JPDO) to plan and coordinate the development of the system. Justification. By 2. ADS- B will use Global Positioning System (GPS) satellite signals to provide air traffic controllers and pilots with much more accurate information that will help to keep aircraft safely separated in the sky and on runways. Aircraft transponders receive GPS signals and use them to determine the aircraft's precise position in the sky. These and other data are then broadcast to other aircraft and air traffic control. Once fully established, both pilots and air traffic controllers will, for the first time, see the same real- time display of air traffic, substantially improving safety. The FAA will mandate the avionics necessary for implementing ADS- B. Next Generation Data Communications (Data Comm). Current communications between aircrew and air traffic control, and between air traffic controllers, are largely by voice. Initially, the introduction of data communications will provide an additional means of two- way communication for air traffic control clearances, instructions, advisories, flight crew requests and reports. With the majority of aircraft data link equipped, the exchange of routine controller- pilot messages and clearances via data link will enable controllers to handle more traffic. This will improve air traffic controller productivity, enhancing capacity and safety. Next Generation Network Enabled Weather (NNEW). Seventy percent of NAS delays are attributed to weather every year. The goal of NNEW is to cut weather- related delays at least in half. En Route Automation Modernization Eram Program DirectvTens of thousands of global weather observations and sensor reports from ground- , airborne- and space- based sources will fuse into a single national weather information system, updated in real time. NNEW will provide a common weather picture across the national airspace system, and enable better air transportation decision making. National Airspace System Voice Switch (NVS). There are currently seventeen different voice switching systems in the NAS, some in use for more than twenty years. NVS will replace these systems with a single air/ground and ground/ground voice communications system. Implementation. In 2. UAS Operational Assessment: Visual compliance - Human-in-the-loop simulation to assess how UAS integration. The computer system the FAA uses at its high altitude en-route centers is considered the backbone of the nation’s airspace system. The system processes. The Next Generation Air Transportation System (NextGen) is a new National Airspace System due for implementation across the United States in stages between 2012 and. Lockheed Martin’s LM-STAR Leidos has a proven track record of delivering improved safety and efficiency across civil aviation. Find out why, from Sidewalk to Sky, we've got it covered. Generation Beyond is a first of its kind, national educational program to bring the science of space into thousands of homes and classrooms across. Radio Technical Commission for Aeronautics (RTCA) Task Force, a joint government and industry group, to participate in the effort. Helicopters flying over the Gulf of Mexico are also using Next. Gen technology to manage poor weather conditions and in Colorado to navigate through dangerous mountain terrain. 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. Specialized Optimized Profile Descents, also known as Initial Tailored Arrivals, have moved from the demonstration phase to operational use at airports in San Francisco, Los Angeles, Miami and Denver. Department of Transportation Inspector General Calvin Scovel and U. S. 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. Testifying before the House of Representatives aviation subcommittee, Scovel warned that . Dillingham added that the . The result of this change is that many localities are experiencing huge increases in air traffic over previously quiet areas. Complaints have risen with the added traffic and multiple municipalities have already filed suit, with more considering such a move. Records show that 8. Palo Alto are in violation of two separate agreements restricting approach flights to at least 8,0. A report released in October 2. Government Accountability Office found the FAA has made some progress in implementation, but delays threaten to impact costs and benefits. The report also indicates that some key acquisitions may soon encounter delays, which can increase overall acquisition costs as well as costs to maintain current systems. For example, delays in implementing the En Route Automation Modernization (ERAM) program is projected to increase costs by $3. ERAM was meant to replace. For instance, the delivery of ADS- B (Automatic Dependent Surveillance Broadcast) depends on ERAM because ADS- B requires the use of some ERAM functions. The long- term result of this decision is not yet known but it could delay certain SWIM capabilities as well as hinder the progress of other capabilities that depend, in turn, on the system integration that SWIM is intended to provide. Consequently, the midterm (through 2. Next. Gen will be affected by how well FAA manages program interdependencies. Potential budget reductions. According to the report, congress has proposed reducing FAA. Most of this proposed reduction is on Next. Gen and Next. Gen- related spending, as reflected in FAA. FAA will have to balance its priorities to ensure that Next. Gen implementation stays on course while also sustaining the current infrastructure, which is needed to prevent failures and maintain the reliability and efficiency of current operations. Effect of delays on FAA. A previous GAO report on environmental impacts at airports indicated that the changes in aircraft flight paths that will accompany Next. Gen efforts would affect some communities that were previously unaffected or minimally affected by aircraft noise and expose them to increased noise levels. The report found that addressing environmental impacts can delay the implementation of operational changes, and indicated that a systematic approach to addressing these impacts and the resulting community concerns may help reduce such delays. It is worth noting that the FAA is working on developing environmental review processes that affect Next. Gen activities. The route has resulted in strong opposition from neighboring communities in the borough of Queens, NY. The FAA still refuses to conduct a full environmental impact study on the route.
