N_AERONAUTIC_T5_019 Category T5 easements relate to aeronautical clearance easements established pursuant to articles L. 6351-1 1° and L. 6351-2 to L. 6351-5 of the Transport Code (formerly R. 241-1 to R. 242-3 of the Civil Aviation Code) These are easements, known as aeronautical clearing services, created to ensure the safe operation of aircraft, excluding radio easements. They are defined as: — by a plan of aeronautical alternate easements (PSA) drawn up for each aerodrome referred to in Article L.6350-1 (1) and (2) of the Transport Code (formerly R. 241-2 of the Civil Aviation Code), — or by provisional safeguard measures which may be implemented in the event of an emergency, before being included in an approved SAAP. These aeronautical clearance easements shall include: — the prohibition of creating or the obligation to modify or even remove obstacles which may constitute a danger to air traffic or which are harmful to the operation of safety devices (blow, radio or meteorological) established in the interest of air navigation, — the prohibition on carrying out major repairs or improvements on buildings and other works subject to aeronautical easement, exempted from the building permit without authorisation from the administrative authority. This resource describes the surface plates of grade T5 easements, namely clearance surfaces: — area bounded by the support perimeter; — landing hole; — take-off hole; — lateral surfaces; — inner horizontal surface; — conical surface; — complementary surfaces associated with precision landings (obstructed areas)N_AERONAUTIC_T5_019 T5类地役权指依据《运输法典》（原《民用航空法典》第R. 241-1条至第R. 242-3条）第L. 6351-1条第1目及第L. 6351-2条至第L. 6351-5条设立的航空净空地役权（aeronautical clearance easements）。 此类地役权又称航空净空服务地役权，旨在保障航空器安全运行，不包含无线电地役权（radio easements）。其定义方式如下： — 针对《运输法典》（原《民用航空法典》第R. 241-2条）第L.6350-1条第(1)、(2)款提及的每个机场，制定航空备用净空地役权方案（plan of aeronautical alternate easements，简称PSA）； — 或在紧急情况下实施临时保障措施，待后续纳入经批准的SAAP。 此类航空净空地役权包含以下内容： — 禁止搭建可能危及空中交通、或损害为航空导航设立的安全设施（blow、无线电或气象设施）运行的障碍物，或要求对该类障碍物进行改造甚至移除； — 禁止在未经行政主管部门授权的情况下，对受航空地役权约束且可豁免建筑许可的建筑物及其他工程进行大修或改造。 本数据集描述T5级地役权对应的净空面图，即净空面，包括： — 由支撑边界界定的区域； — 着陆区； — 起飞区； — 侧方面； — 内水平面； — 锥形面； — 与精密进近相关的辅助面（障碍物区域）
