Research on Airworthiness Verification and Simulation Methods for Civil Aircraft Interrupted Landing

Go-around is a crucial aspect of ensuring aircraft safety and airworthiness. It is therefore essential to conduct verification of the aircraft's go-around procedure to demonstrate compliance. In accordance with regulatory requirements, for instances of interrupted landings with one engine inoperative above the decision height, it is necessary to verify height loss and trajectory for airworthiness under entire envelope including icing conditions. Due to the numerous dimensions and constraints involved in the go-around procedure, including configuration, temperature, altitude, weight, and icing conditions, criticality analysis is challenging. Currently, traditional experimental verification necessitates the planning of a significant number of test points, which is costly and time-consuming. To address this issue, a simulation method for height loss and trajectory in a go-around was proposed. The feasibility of this method was demonstrated by comparing the flight test results with the simulation results for civil aircraft airworthiness verification. This effectively reduced the cost and cycle of compliance verification work. Furthermore, the method has the advantages of high efficiency, high safety, and repeatability, providing a reference for subsequent civil aircraft airworthiness verification.
