With the prosperous development of civil aviation transportation in China,there are huge challenges to civil aviation safety,especially the difference in climate between north and south of China,which increases the possibility and hidden danger of civil transport aircraft operating on contaminated runways.We must vigorously carry out research on the take-off and landing performance of civil transport aircraft on contaminated runways.At present,ICAO has stipulated a new contaminated runway condition global reporting format,which divides the length of the runway into three sections and reports the runway condition of each third section in turn,making the runway condition report more accurate,increasing the accuracy of the evaluation of the performance of take-off and landing on contaminated runways,and improving the economic efficiency of airlines and airports.This paper compares domestic and foreign regulations and regulatory documents on the operation of contaminated runways,and analyzes the differences in regulations on the operation of contaminated runways between different countries and institutions.Analyzes the composition and mechanism of the contaminant drag and establishes a calculation model for the contaminant drag based on the proposed method of AMC 25.1591.According to the force and motion state of the civil transport aircraft during the take-off and landing process,calculation models for take-off and landing performance on contaminated runway are established,and a Chinese made aircraft is taken as an example to simulate and calculate the models to analyze the impact of the contaminated runway on the take-off and landing performance of civil transport aircraft.Through the analysis of ICAO’s runway condition report,the calculation method of landing distance under different combinations of runway conditions is established,the feasibility of the method is verified through examples,and the influence of different runway condition combinations on landing distance is analyzed.The research can provide reference for the daily operation of airlines and the optimization of Chinese made performance software. |
