- Q6970266 abstract "The National Airspace System (NAS) is the airspace, navigation facilities and airports of the United States along with their associated information, services, rules, regulations, policies, procedures, personnel and equipment. It includes components shared jointly with the military. It is one of the most complex aviation systems in the world and services air travel in the United States and over large portions of the world's oceans.A flight through the NAS typically begins and ends at an airport which may be controlled (by a tower) or uncontrolled. On departure, the aircraft is in one of five of the six classes of airspace administered by the Federal Aviation Administration (FAA), and different flight rules apply to each class. Depending on the class of airspace and flight conditions, communication with controllers may or may not be required. Operation of each flight is always the responsibility of the pilot in command, but air traffic controllers give instructions for sequencing and safety as needed. When a controlled flight is airborne, control passes from the tower controller who authorized the takeoff, if the airport is controlled. The next step is typically Terminal Radar Approach Control or TRACON which may be identified as "approach" or "departure". Between the sectors administered by TRACONs are areas of Air Route Traffic Control Center (ARTCC) typically referred to on the radio as "Center". A flight is handed off from one Center to another until it nears its destination, when control is transferred to the TRACON serving the destination, and ultimately to the tower controller serving the airport. Some airports have no TRACON around them, so control goes directly to or from a Center, and some flights are short enough that control is kept within one or more TRACONs without ever being passed to Center. As of February 2015 the NAS is transitioning to a new system known as NextGen, which is a satellite-based navigation system. It lets pilots know the exact locations of other aircraft in the NAS, which accommodates more traffic and improves safety. Using NextGen to land will let pilots arrive at airports more predictably and efficiently which helps improve passenger and cargo loading. NextGen is being phased in piece by piece.Approximately 14,500 air traffic controllers, 4,500 aviation safety inspectors, and 5,800 technicians operate and maintain services for the NAS. It has more than 19,000 airports and 600 air traffic control facilities. In all, there are 41,000 NAS operational facilities. In addition, there are over 71,000 pieces of equipment, ranging from radar systems to communication relay stations. On average, about 50,000 flights use NAS services each day.".
