Abstract
Current air traffic control rules require that the fixed distance separations between aircraft operations be maintained on a runway. The runway capacity is inversely proportional to the time headway between operations. In such a case that the distance separation is settled, the time headway could be reduced by increasing the approach speed of aircraft. However, as the approach speeds increase, the runway occupancy times of landing aircraft will increase, and consequently, the runway capacity will decrease. In order to maximize the runway capacity under the above-mentioned conditions, in this paper, a method is proposed to match approach speeds of aircraft with distance separations by using the mathematical optimization techniques. Based on the numerical results obtained, the factors that restrict the further increase of runway capacity are made evident
