Safe and regular aircraft operations require a permanent monitoring and assessment of the environment surrounding an aerodrome from developments and activities that may have adverse effects.
To support stakeholders incl. the local communities and project developers with identifying height restrictions for proposed developments such as high-rising buildings, antennae or wind turbines, aerodrome safeguarding maps may be utilized.
Such safeguarding maps show height restrictions in the vicinity of aerodromes and can incorporate various requirements, such as:
- Obstacle Limitation Surfaces (OLS) as defined by ICAO Annex 14, EASA CS-ADR-DSN or national regulations,
- obstacle protection surfaces for visual aids such as visual slope indication systems (e.g. PAPI) or approach lighting systems,
- protection areas of instrument flight procedures as defined in ICAO Document 8168 (PANS-OPS),
- obstacle accountability areas according to ICAO Annex 6, EASA Air OPS or national regulations,
- protection areas of visual flight operations as defined by national regulations,
- and more.
The different requirements may be combined and merged into one safeguarding map showing maximum obstruction heights to which no impact on the safety or regularity of flight operations is expected. As aerodrome safeguarding maps incorporating various requirements can be complex, a simplification of areas and height restrictions can be useful for easier application.
