Next Generation Air Transportation System
The Next Generation Air Transportation System (NextGen) is an ongoing United States Federal Aviation Administration (FAA) project to modernize the National Airspace System (NAS). The FAA began work on NextGen improvements in 2007 and plans to finish the final implementation segment by 2030. The goals of the modernization include using new technologies and procedures to increase the safety, efficiency, capacity, access, flexibility, predictability, and resilience of the NAS while reducing the environmental impact of aviation. History The need for NextGen became apparent during the summer of 2000 when air travel was impeded by severe congestion and costly delays. Two years later, the Commission on the Future of the U.S. Aerospace Industry recommended that a multi-agency task force develop an integrated plan to transform the U.S. air transportation system. In 2003, Congress enacted the Vision 100 – Century of Aviation Reauthorization Act, which established the Joint Planning and De ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Separation (aeronautics)
In air traffic control, separation is the name for the concept of keeping an aircraft outside a minimum distance from another aircraft to reduce the risk of those aircraft colliding, as well as prevent accidents due to secondary factors, such as wake turbulence. Separation can also apply to terrain, obstacles, and controlled airspace, wherein an aircraft must stay at a minimum distance from a block of airspace; as an example, all aircraft must be approved by the controller who "owns" the airspace before the aircraft is approved to enter that sector. Air traffic controllers apply rules, known as ''separation minima'', to do this. Pairs of aircraft to which these rules have been successfully applied are said to be ''separated'': the risk of these aircraft colliding is therefore remote. If separation is lost between two aircraft, they are said to be in a ''conflict''. When an aircraft passes behind or follows another aircraft, wake turbulence minima are applied due to the effect ...

Air Traffic Controller
Air traffic control specialists, abbreviated ATCS, are personnel responsible for the safe, orderly, and expeditious flow of air traffic in the global air traffic control system. Usually stationed in air traffic control centers and control towers on the ground, they monitor the position, speed, and altitude of aircraft in their assigned airspace visually and by radar, and give directions to the pilots by radio. The position of air traffic controller is one that requires highly specialized knowledge, skills, and abilities. Controllers apply separation rules to keep aircraft at a safe distance from each other in their area of responsibility and move all aircraft safely and efficiently through their assigned sector of airspace, as well as on the ground. Because controllers have an incredibly large responsibility while on duty (often in aviation, "on position") and make countless real-time decisions on a daily basis, the ATC profession is consistently regarded around the worl ...

Single European Sky ATM Research
Single European Sky ATM Research (SESAR) is a collaborative project to completely overhaul European airspace and its air traffic management (ATM). The actual program is managed by the SESAR Joint Undertaking as a public–private partnership (PPP). Project The SESAR project is composed of three phases: * a Definition phase (2004–2008) to deliver an ATM master plan defining the content, development, and deployment plans of the next generation of ATM systems. This definition phase is led by Eurocontrol, and co-funded by the European Commission under the Trans-European Transport Networks program and executed by a large consortium of all air transport stakeholders. * a Development phase (2008–2013), to produce the required new generation of technological systems and components as defined in the definition phase. This phase (budget: 2.1 billion euro) is managed by the SESAR Joint Undertaking. * a Deployment phase (2014–2020), for large-scale production and implementation o ...

Air Traffic Management
334x334px, Air traffic management (ATM) is an aviation term encompassing all systems that assist aircraft to depart from an aerodrome, transit airspace, and land at a destination aerodrome, consisting of air traffic services (ATS) including air traffic control (ATC),, airspace management (ASM), and air traffic flow and capacity management (ATFCM). The increasing emphasis of modern ATM is on interoperable and harmonised systems that allow an aircraft to operate with the minimum of performance change from one airspace to another. ATC systems have traditionally been developed by individual States that concentrated on their own requirements, creating different levels of service and capability around the world. Many Air Navigation Service Providers (ANSPs) do not provide an ATC service that matches the capabilities of modern aircraft, so ICAO has developed the Aviation System Block Upgrade (ASBU) initiative in order to harmonise global planning of technology upgrades. In the Asia/Paci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Next Generation Data Communications
Next Generation (NextGen) Data Communications (Nexcom or Data Comm), an element of the Next Generation Air Transportation System, will significantly reduce controller-to-pilot communications and controller workload, whilst improving safety. NextGen comprises complex integrated and interlinked programs, portfolios, systems, policies, and procedures. NextGen has modernized air traffic infrastructure in communications, navigation, surveillance, automation, and information management. Description In the current United States National Airspace System, all communications with airborne aircraft is by voice communications. Aircraft route of flight revisions must be communicated through multiple change-of-course instructions or lengthy verbal reroute instructions, which must be repeated; are prone to verbal communications errors; and entry errors into an aircraft's flight management system. The use of voice communication is labor and time intensive and will limit the ability of the Feder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Airspace System Voice Switch
The United States National Airspace System Voice Switch (NVS) project, a part of the Next Generation Air Transportation System (NextGen), aims to establish a single set of scalable voice switches that can support a dynamic flow of air traffic. Voice communications network flexibility is essential for the Federal Aviation Administration (FAA) to increase air traffic control network flexibility. Description Voice communications is a fundamental part of providing air traffic control services. Both air-to-ground and ground-to-ground voice communications are essential for the en route, flight service and terminal domains of aircraft flights to provide safe, orderly and efficient flow of air traffic. In the early years of the twenty-first century, air traffic control air-ground and ground-ground voice communications are managed on a geographical basis. The equipment used is a mixture of seventeen different types, some already 20 years old. Current voice communications switches are very ...
