一种风干扰下压点转弯方法、装置及飞行管理系统
By constructing an approximate display arc and transition path under wind interference, the problem of not being able to simultaneously handle large bank angles and transition path display during high-pressure point turns in existing technologies is solved. This enables continuous and smooth reference tracks and rapid and stable turns in the flight management system, thereby improving flight safety.

AI Technical Summary
Under wind interference, existing flight management systems cannot simultaneously maintain a high bank angle for an extended period and display a transition path during point turns, resulting in lengthy turns or the absence of a transition path display, which puts psychological pressure on pilots.
By initializing the radius of the arc, calculating the position and angle of the center, and combining the aircraft's motion under windless and windy conditions, an approximate display arc is constructed, and the transition path is guided and displayed. The average ground speed of steady-state turning is calculated using the flight management system, the radius and direction of the arc are adjusted, and the result is output to the cockpit display system.
It enables the flight management system to provide a continuous and smooth reference track under wind interference, guiding the aircraft to make rapid turns at large angles and recover smoothly, reducing airspace occupation, improving the speed of turning at the pressure point under wind interference and the smoothness of transition recovery, and enhancing flight safety.
