In the United States, some alterations to traffic control procedures are being examined.

• The Next Generation Air Transportation System examines how to overhaul the United States national airspace system.
• Free flight is a developing air traffic control method that uses no centralized control (e.g. air traffic controllers). Instead, parts of airspace are reserved dynamically and automatically in a distributed way using computer communication to ensure the required separation between aircraft.

In Europe, the SESAR[6] (Single European Sky ATM Research) Programme plans to develop new methods, new technologies, new procedures, new systems to accommodate future (2020 and beyond) Air Traffic Needs.
Many countries have also privatized or corporatized their air navigation service providers.
Change in regulation in admittance for possible A.T.C.'s regarding their eye-refraction and correction thereof by technology has been proposed.
