随着民航机场建设的不断发展,机场净空安全已成为保障机场运行和飞行安全的前提,而机场周围障碍物直接影响到机场的安全与运行。在实际操作中如何把握障碍物限制面(即附件14面)与ILS障碍物评价面(即OAS面)的关系,对于保证机场净空安全和建立良好的飞行程序有着现实的意义,本文就此问题作一简要论述。一、如何区分附件14面与OAS面在评估机场障碍物时我们经常使用附件14面与OAS面,如何区分和掌握上述两面十分重要。首先从定义上讲,障碍物限制面(附件14面)是作为限制障碍物增长的规划面。规定在机场周围保持无障碍物的空域,使准备使用该机场的航空器能够安全运行,并防止由于机场
With the continuous development of civil airport construction, the airport clearance security has become a prerequisite for ensuring airport operation and flight safety. However, the obstacles around the airport directly affect the safety and operation of the airport. How to grasp the relationship between obstacle restriction surface (Annex 14 surface) and ILS obstacle evaluation surface (OAS surface) in actual operation has realistic significance for ensuring the airport clearance security and establishing a good flight program. This article on this issue A brief discussion. First, how to distinguish Annex 14 and OAS surface in the assessment of airport obstacles We often use Annex 14 and OAS surface, how to distinguish and grasp the above two is very important. First, by definition, the obstacle limitation surface (Annex 14 surface) is used as a planning surface to limit the growth of obstacles. Provides for the maintenance of airspace without obstructions around the airport to enable safe operation of the aircraft ready for its use and to prevent accidents caused by airports
