Abstract

In order to prevent plane from overshooting runway on landing, a method was proposed to predict flights' actual operating landing distance based on similarity theory. Firstly, combined dimensional analysis with main factors that affect actual landing distance of aircraft, dimensionless equation that characterize operating landing distance was obtained. Then, digital flight data was used to further establish equation that predict flights' actual operating landing distance under different touchdown pitch angles. Finally, prediction values of equation were compared with actual operating landing distance of aircrafts. The results show that this method is able to predict flights' actual operating landing distance and deviation between predicted value and practical value is minimum under condition of small touchdown pitch angle. The maximum absolute error is less than 50 meters, and the maximum relative error is about 3%. © 2021 China Safety Science Journal
