一种多转弯方式组合的航线转弯弧画法

在座舱显示系统的导航显示器中经常需要显示飞机的规划航线，航线中的每个航路点可能采用不同的转弯方式，例如压点转弯、向点转弯、绕点转弯等。本文给出了一种根据各航路点的转弯方向、转弯半径、转弯方式确定各航路点转弯弧的圆心、转弯弧起始点、转弯弧结束点的计算方法。

A Method to Compute Turn-Circle in Multiple Turn-style Combination

In the ND of cockpit display system, there’s a need to display air route of aircraft. Each waypoint may apply to different turn style. This paper provides a method to compute the center point, head point and rear point of a turn circle according to way-point’s turn-style, turn radius and turn direction.
