International regulations issued by the International Civil Aviation Organization (ICAO), as set out in Annex 14, together with requirements from the European Union Aviation Safety Agency (EASA), specify that airspace surrounding aerodromes must be kept free of obstacles.

To meet these requirements, Obstacle Limitation Surfaces (OLS) are established, which should ideally remain free from any penetrations.

Altitude Nexus supports aerodromes and regulatory authorities in developing the applicable OLS and in identifying and assessing any obstacle penetrations.

Obstacle Limiting Surfaces (OLS) are essential for airport safety and planning, establishing limits that guarantee that buildings and objects in the vicinity of airports and heliports do not affect air operations. Its correct evaluation and modelling make it possible to prevent interference with the takeoff, approach and manoeuvre trajectories of aircraft.

• Evaluation of maximum heights allowed for buildings, antennas, mills and other structures close to controlled air spaces.

• Detection of penetrations and impact analysis, with mitigation proposals to guarantee operational safety.

• Preparation of detailed technical reports, accompanied by graphic representations.

• Integration with BIM, CAD, GIS and Google Earth tools, facilitating the visualization and efficient management of data.
