Introduction to Obstacle Limitation Surfaces (OLS)

This course enables participants to establish and to evaluate the ICAO/EASA Obstacle Limitation Surfaces (OLS) for aerodromes. 

Safe airport operations demand a permanent monitoring of obstacles in the close proximity of airports. The construction of new infrastructure or changes to airport operations require systematic obstacle evaluations and assessments to maintain an acceptable level of safety. 

International regulations from the International Civil Aviation Organization (ICAO) as described in Annex 14 Vol. I as well as regulations from European Union Aviation Safety Agency (EASA) as described in the CSADRDSN specify airspace around aerodromes to be maintained free from obstacles. For that purpose, Obstacle Limitation Surface (OLS) are described, which ideally shall not be penetrated by an object.  

The objective of this training course is to provide a comprehensive overview of the Obstacle Limitation Surface (OLS). Attendees will learn how to establish the relevant Obstacle Limitation Surfaces and how to determine OLS infringements. 

Please note:

This course can also be booked as an in-house version in German - however, the course material is only available in English.
