The ATC services are availed to many users in most countries. There are two kinds of airspace, the controlled airspace, and the uncontrolled airspace. In the controlled airspace, the controllers are responsible for the separation of some or all aircraft. In the uncontrolled airspace, the aircraft is allowed to fly without the air traffic control system. Air traffic controllers in most cases only issue instructions or flight instructions which the pilots are expected to follow (Mattson, 2006). The instruction at times may not be followed by the pilots in the case of emergencies because the pilot has the final responsibility for the safety of any aircraft.&nbsp.The secretary then established a Joint Planning and Development Office at the Federal Aviation administration that comprised of members drawn from various departments including the department of defense, homeland security, commerce, NASA, transportation and the white house office of science and Technology Policy. These representatives from the various departments were supposed to come up and implement an integrated plan for NextGen. The following year in 2004, the department of transportation launched the integrated plan for the Next generation Air Transportation system that showed the goals, objectives, and requirements that were necessary to come up with the NextGen System (Joint Planning and Development Office, 2007).
Therefore NextGen is only a term used for describing the ongoing transformation of the National Airspace System (NAS). It represents an evolution from the current ground-based system of air traffic control to a satellite-based system of traffic management.
