Research On Airport Efficiency And Company Benefit Based On RNP AR Operation

With the development and application of RNP AR,it is very important to study the airport effectiveness and company efficiency.In this paper,factors such as airport capacity,aircraft delay time,noise impact and fuel consumption under RNP AR operation are selected as analysis indexes of airport efficiency and company benefit.This paper first summarizes the development and operation of RNP AR at home and abroad,analyzes the typical cases at home and abroad,and compares the operation regulations of RNP AR at home and abroad.Through the research and analysis of runway configuration and multi-runway operation specifications,the airport runway capacity model under RNP AR operation mode is established.Secondly,the airport capacity of Shenzhen airport under RNP AR operation is simulated by using AirTOp simulation software.Under the daily flight capacity of 1200 / 1400 / 1600,the airport capacity of different RNP AR occupancy rates under the single runway operation,isolated operation,related parallel approach independent departure,independent approach independent departure operation modes are simulated and analyzed respectively,and different RNP AR occupancy rates are obtained through simulation The simulated runway capacity is compared with the capacity based on historical data and mathematical model.Finally,through the comparison and analysis of the noise impact of RNP AR and RNAV operation in Shenzhen airport,the noise impact areas under the noise levels of 50 dB,55dB and 60 dB are simulated and calculated respectively,and the RNP AR program is used to avoid noise sensitive points and reduce the noise impact;combined with the fuel cost and time cost analysis,the RNP implementation of airlines in Shenzhen airport is analyzed through comparing the track distance and descent profile,the fuel consumption model is used to simulate the fuel consumption of the approach of runway 34 of Shenzhen airport,The analysis shows that the time cost of RNP AR approach can be saved by 1056 hours and fuel economy can be saved by 24.816 million yuan.
