NIU Zhi - bo, ZHANG Chang - an (Heilongjiang Provincial Administration of Civil Aviation, Harbin, Heilongjiang 150040, China)
The purpose of drawing the map of airport clearance limited plane and obstacle positions is to grasp the relationships between clearance limited plane and obstacles. By using the three - dimensional traversing as the basic control and the three dimensional forward intersection method to determine the horiontal and vertical positions of obstacle points. Then the special map is drawn with the said data.
