Key Technology Research on the Reproduction of Flight Level Path in Approach and Landing Phase

The reproduction of flight path during the aircraft approach and landing phase is an important part of flight unsafe incidents investigation. This article gives a method of extracting and processing flight parameter aiming at the problem that flight record data has a poor integrality, high rate of change and is hard to generated by flight path directly in that phase. In this article the airport environment which around aircraft in the landing phase is modeled, the flight path is reproduced by latitude and longitude and flight performance data, the flight path is calibrated in two ways, which one using a specific location point and other using the average latitude and longitude position point. The flight path which calibrated in the approach and landing phase which meets the needs of the project is obtained.
