Research of Climb Performance Calculation Method and Program Implementation for Civil Aircraft Flight Test

Climb test flight is one of the important flight test subjects in performance test flight. Through the analysis of climb theory, this paper gives the calculation method and process of the test aircraft climb performance parameters after only the flight test data and the polar curve data corrected by the flight test data are obtained. Through flight testing proves that the calculation method of parameters such as climb rate and climb gradient weight limit in this paper is feasible, and can provide a reference for the calculation requirements of parameters related to climb performance during flight tests of new aircraft.
