The flight scene simulation is an important part of the flight simulation, and its visual effect and reality degree will influence the whole flight simulator directly.

飞行视景仿真是飞行仿真的一个重要组成部分，它的视觉效果和逼真程度将直接影响整个飞行模拟器的逼真度。

Due to the lower flight height and the slower flight speed of helicopter, Compared with the fixed wing airplane, the visual system of helicopter flight simulator has the particularity in visual scene.

由于直升机飞行高度低、飞行速度较慢，直升机飞行模拟器的视景系统具有特殊性。
