高高原机场飞行程序设计中的风螺旋线模型

摘要

标准的风螺旋线模型不能真实刻画高高原机场航线转弯保护区外边界。根据飞行程序对转弯区外边界的定义，提出并建立精确的风螺旋线模型，用最佳平方逼近算法探寻模型中风速与高度的关系，确立合适的风速高度模型并进行优化和对比。仿真图像表明：精确的风螺旋线模型使得转弯保护区设计更加科学可靠。在保证飞行安全的情况下，提高了有限的空域资源利用率。%A standard wind spiral model cannot simulate the outer boundary of a turning area in high plateau airport.Based on the definition of outer boundary of a turning area by flight procedures,this paper put forward and established a precise wind spiral model,exploring the relationship between wind speed and height by using the optimal square approximation algorithm,with an appropriate wind speed and height mod-el finally established and optimized.The simulation images suggest that the precise wind spiral model can make the turning area design more scientific and reliable,and improve the airspace utilization rate while en-suring flight safety.
