The sustained increase in air traffic in the USA has resulted in over 5000 aircraft in the air during daytime controlled by the Federal Aviation Administration air traffic control system. This system also controls military aircraft while in transit to military operational areas. There is a growing trend to privatise air traffic control so advances in technology can be financed. Aircraft separation standards and the number of runways available determine the operational capacity of the air transport system. A typical air controller can maintain situational awareness on 4-7 aircraft, but if more aircraft are involved, teamwork becomes necessary. The planning of a typical flight is described. Demand for air travel is expected to exceed supply and delays are anticipated. Aircraft separation standards may need to be decreased, radar surveillance may need to be replaced by GPS, and aircraft takeoff delayed in response to predicted landing delays.
