Plans for the control of air traffic in the Greater Kansas City Terminal Area were evaluated to determine optimum control procedures, traffic flow patterns and equipment configurations. The dynamic air traffic control simulation facilities at the National Aviation Facilities Experimental Center were used in conducting the evaluation. The Federal Aviation Agency Central Region concept combined the control of instrument flight rule traffic operating at Kansas City Municipal, Mid-Continent International, RichardsGebaur AFB, Olathe NAS, Sherman AAF and St. Joseph Airports at the Kansas City Terminal Radar Approach Control Facility. In addition the concept required that both Kansas City Municipal Airport and the Mid-Continent International Airport be considered as a primary terminal. The evaluation was conducted accordingly. It was concluded that the control procedures, traffic flow patterns, and equipment configurations contained in the final plan were optimum. It was recommended that the final plan be considered for implementation. (Author).
