Safe air operations require a permanent monitoring and assessment of possible infringements of applicable control surfaces defined e.g. in ICAO Annex 14 OLS, PANS-OPS, ICAO EUR DOC 015 or their national implementation.
This process, called "safeguarding", shall facilitate the safe integration of new constructions around airports or air traffic control equipment. While regulations may be at a first sight restrictive, these also allow a great flexibility to enable urban or wind farm development - provided a systematic assessment of the possible impacts of new constructions on aviation is conducted and demonstrate that the safety of air operations is not compromised.
Such assessment, also known as "aeronautical study" is one of the core competence of airsight. Not only we have conducted over hundred of such assessments and are accredited or recognised by several aviation authorities to provide such services to project developers, but we also contribute in the development of the national and international regulations to make aviation safer.
Our objective and added value is to find operational or technical solutions meeting the needs of airport operators, airspace users and project developers, and our experience in this field is almost unprecedented.
Obstacle Assessments & Aeronautical Studies
The control and management of obstacles is critical for airport operators as well as for construction projects within the vicinity of aerodromes.
Physical Safeguarding is a process aiming at preventing collisions between aircraft and obstacles - such as new constructions or objects. It consists in controlling that obstacles do not infringe complex 3D-surfaces defined by international or national requirements around aerodromes (e.g. ICAO Annex 14 Obstacle Limitation Surfaces).
In many cases however, infringements cannot be avoided: it requires a detailed assessment, also called "aeronautical study", to assess if the proposed development has an impact on air operations and to develop mitigation measures to ensure that safety is not compromised.
The assessment of obstacles around airports and their impact on flight operational safety is a core competency of our team: we have conducted over 100 projects in this field since 1999, and are internationally one of the most renowned experts in this field.
New buildings or objects shall not interfere with the air traffic control Communication, Navigation and Surveillance systems.
CNS systems are very vulnerable to adverse effects caused by physical obstacles such as buildings, cranes, wind turbines as well as mobile objects (aircraft, construction equipment).
Therefore, to ensure safe air operations, national and international aviation regulations define protection surfaces and approval procedures for new developments and constructions (e.g. ICAO EUR DOC 015 – managing Building Restricted Areas - BRA, ICAO Annex 10, National Requirements, etc.).
The rules and associated concepts introduced by these regulations are complex and frequently misunderstood by the stakeholders. As protection surfaces are very restrictive, it often leads to conflicts between developers and airspace users – though, in many cases, technical solutions may be available to resolve or minimise adverse impacts.
airsight assists project developers in the project planning phase in minimising interference issues with CNS systems, while avoiding too costly measures (design revisions, relocation, or reorientation), as well as in obtaining the relevant approvals from the authorities and air navigation service providers.

Wind Turbines and Aviation Safety
airsight supports wind farm developers to resolve complex wind farm planning issues related to aviation.
Wind turbines represent a physical obstacle to air operations. To minimise the risk of collision or interferences with CNS systems, the International Civil Aviation Organisation (ICAO) and national authorities developed a set of regulations related to wind turbines in the vicinity of aerodromes. These requirements are nevertheless very complex, and represent a major restriction to new constructions of wind farms.
As demonstrated in numerous projects, airsight can assist project developers in defining and optimising the possible constructible area at an early project stage, as well as to evaluate and mitigate the impact of wind turbines on air operations - while taking into account diverging external stakeholders’ interests (aerodromes, aviation/military authorities, air navigation service providers).
