Calculation models of capacity and delay for closely spaced parallel runway

In order to accurately assess the capacity and delay of closely spaced parallel runway, a time-space diagram was established in accord with realistic operational features, the calculation models of the capacity and delay under the classic mixed operation mode of single runway were referred, departure flights were allowed in the intervals of arrival flights, double queue system theory and logical discursion method were utilized, the calculation models of the capacity and average delay for closely spaced parallel runway were built separately, simulation method was used to check the models, and the calculation result and the simulation result were compared.Comparison result shows that the differentia rate of runway capacity is 0.58%, the maximum differentia rates of the average delay and queue are 1.7% and 1.4% respectively, so the new models reflect the realistic operational situation of closely spaced parallel runway, and are feasible.
