Study On Algorithm Of Aircraft Landing Distance And Example Analysis

Aircraft performance software is a calculation tool which analyzes the parameters of aircraft performance, including taking-off, climbing, cruising, descent and landing performance, in the airline flight operations. In consideration of the information of airport and route, those parameters are achieved, which combines the parameters of aircraft and engine. It also guarantees economies and security of the airline operating. Now in our country, the performance software of almost all airlines’aircrafts are provides by Boeing and Airbus Company. We do not fully master their core technology. With the urgent needs of the commercial production of independent large aircraft, it is very important to develop the excellent performance software which is stable, accurate, independent and easy to use.Aircraft performance software contains a large of the contents, such as taking-off, obstacle of climbing, cruising, descent and landing. Based on the module of landing distance in the aircraft performance software, this article deeply studies calculation method of landing distance. Especially, it discusses an algorithm for the validation of the landing distance and the actual landing distance in accordance with Chinese civil aviation regulations (CCAR25). I design the new model of landing mathematical and the method of calculation, combining with the aerodynamic database and thrust database of a domestic aircraft, and then I show the methods and algorithms of every landing model. Finally, according to actual requirements of the assessment of landing distance at the time of arrival, I calculate, analyze and assess this issue.
