This entity describes where rules exist to protect the operational airspace surounding an airfield. These rules limit the height of structures, vegetation or other activities thus removing physical, operational or navigational impediments to the safe operation of aircraft in the vicinity of an airfield. Data Source: CCC Survey Team with input from CIAL. This entity is intersected with RatingUnit to enable generation of property condition comments. It is spatially abstracted to an area. Entity Type: Concept.本实体用于明确为保护机场周边运行空域而制定管制规则的范围。此类规则对建（构）筑物、植被的高度及其他相关活动加以限制，以消除机场周边区域内阻碍航空器安全运行的物理、运行及导航障碍。数据源：CCC勘测团队（CCC Survey Team），并吸纳了CIAL（CIAL）的相关输入。本实体与评级单元（RatingUnit）开展空间相交分析，以支持设施状况注释的生成。该实体在空间上被抽象为面状区域。实体类型：概念（Concept）。
