Abstract: In aviation operations, the landing phase, particularly the flare stage, plays a critical role, directly affecting flight training quality and flight safety. This paper investigates the influence of crosswind on the aerodynamic characteristics of the L-39NG aircraft using numerical simulation with Ansys software. The results show that crosswind increases drag, reduces lift, and generates lateral force, thereby affecting stability and controllability during landing. The study provides a scientific basis for improving operational efficiency and enhancing aircraft safety.
