Effects of Landing Approach Methods and Separation Intervals on Single Runway Landing Capacity

摘要

A study was conducted to determine the effectiveness of seven landing approach methods using current separation intervals, and in combination with reduced separation intervals. It was determined that of the seven methods studied, only the dual-path and dual-path-curved methods provided significant benefits over the current method when the current separation intervals were used. With all the methods, it was found that the landing operations decreased as the proportion of heavy aircraft in the landing mix increased.nReducing the current separation intervals to 5.56 km (3 n. mi.) for large aircraft following heavy aircraft was not particularly advantageous for any method in the range of typical landing mixes. Reducing the current intervals to 3.70 km (2 n. mi.), however, increased the landing capacity by 65 percent for the current method in the range of typical mixes of aircraft. With either of the reduced intervals, there was also a beneficial trend toward increasing landing capacities with increasing proportions of heavy aircraft.
