The largest cause of National Airspace System (NAS) air traffic delays is weather, which was responsible for 75 percent of system-impacting delays of more than 15 minutes from June 2017 to May 2022. [ 150 ] [ 151 ] With more accurate and timely weather predictions, airports and airlines could prevent as many as two-thirds of weather-related ...
It is the most controlled airspace and requires a pilot to carry an Instrument Flight Rating and proper clearance no matter what type of aircraft is being flown. Pilots are also required to change their altimeter settings to 29.92 inHg to ensure all pilots within the airspace have the same readings in order to ensure proper altitude separation. [6]
The NASP concept is thought to have been derived from the "Copper Canyon" project of the Defense Advanced Research Projects Agency (DARPA), from 1982 to 1985. In his 1986 State of the Union Address, President Ronald Reagan called for "a new Orient Express that could, by the end of the next decade, take off from Dulles Airport, accelerate up to 25 times the speed of sound, attaining low earth ...
(in the US, NAS refers to the Whole Air Traffic System - National Airspace System) 1) ROUTE PROCESSING - Convert a flight plan into a series of fixes. For each fix, determine what time the flight will arrive, at which height it will be and determine which air traffic control team (Sector) are responsible for that geographical space.
The FAA's National Airspace System (NAS) enterprise architecture is the blueprint for transforming the current NAS to the Next Generation Air Transportation System (NextGen). The NAS service roadmaps lay out the strategic activities for service delivery to improve NAS operations and move towards the NextGen vision.
The Airspace Operations and Safety Program (AOSP), which works with the FAA to develop technologies to support NextGen and improve navigation automation and safety.

It identifies existing and proposed airports that are significant to national air transportation in the U.S., and thus eligible to receive federal grants under the Airport Improvement Program (AIP). It also includes estimates of the amount of AIP money needed to fund infrastructure development projects that will bring these airports up to ...
