新型精密进近航道指示方法研究

针对现有目视进近下滑坡度指示系统存在的问题和缺陷，研究了一种新型精密进近航道指示方法。该方法仅用三台灯具，黄、绿、红三种颜色就能为进近中的飞行员提供太高、较高、稍高、正对、稍低、较低、太低七种目视进近坡度指示信号。该方法比现行的进近坡度指示系统更有利于飞行员快速判别和调整飞机的进近姿态，可以显著提高飞机着陆准确率，保证飞机进近和着陆安全。

Research of the Precision Approach Path Instruction Method

Aim at current existent problems and defects in visual approach slope indicator, a new Precision Approach Path instruction method has studied. The instruction method can provide seven kinds of Indicators which are SLIGHTLY HIGH, HIGHER, TOO HIGH, CORRECT PATH, SLIGHTLY LOW, LOWER and TOO LOW for pilots during approach for visual landing. To compare the new instruction method with current system, the new instruction method is more advantaged and convenient for pilots who distinguish and adjust gesture of plane approach quickly; it can obviously enhance the airport ability of wartime existence, the accuracy of plane landing, it also can ensure flight safety.
