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 CS-ADR-DSN 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. OLS infringements may be acceptable though, if an obstacle assessment or aeronautical study shows that there is no adverse impact on safety of flight operations.

The objective of this training course is to provide a comprehensive overview of aerodrome safeguarding and the assessment of obstacles in the vicinity of aerodromes. The course is designed for all persons involved in this complex subject, including aerodrome, Civil Aviation Authority personnel, or project developers.

The applicable Obstacle Limitation Surfaces (OLS) are presented and discussed in detail.

In addition, further related aspects such as the protection of visual and instrument flights (VFR, IFR), contingency operations, visual and non-visual aids for air navigation (CNS – communication, navigation and surveillance facilities) as well as further obstacle requirements are presented.

An introduction of instrument flight procedures and their obstacle protection areas is provided (according to ICAO Document 8168 "PANS-OPS"), incl. departure and approach procedures as well as specifics of the Visual Segment Surface (VSS) and Obstacle Clearance Surface (OCS).

Attendees will learn, notably by means of exercises, how to assess relevant Obstacle Limitation Surfaces, to evaluate the significance of penetrating obstacles and to develop appropriate safety measures where necessary.

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

Trainer

Malte Karger, Dipl.-Ing.

Malte is responsible for flight procedure design and obstacle assessments of airsight’s consulting division. He is also a renowned and appreciated trainer, sharing his knowledge and practical experience with other industry experts in airsight’s scheduled as well as customised in-house training courses in countries such as Germany, Greece, Switzerland and Turkey.

As an advisor of ICAO’s Instrument Flight Procedure Panel (IFPP) in the capacity of a field expert, Malte participates in the Obstacle Limitation Surfaces Task Force (OLSTF).

Malte acquired extensive experience on international projects dealing with obstacle assessments and aeronautical studies for clients such as Berlin, Dubai, Hamburg, Luxembourg, Malta, Nuremburg, Stuttgart and Warsaw Airports as well as for several smaller airfields. Furthermore, he conducted numerous flight procedure design projects (conventional and RNAV/PBN)  for Airports, for Airlines (e.g. Air Austral, Air Transat) as well as for Air Navigation Service Providers such as MATS (Malta Air Traffic Services) and Romanian Air Traffic Services Administration (ROMATSA). 

Sierk Törl, Dipl.-Ing.

Sierk is a team member of airsight’s “Aerodrome Safeguarding and Flight Procedures” division. At airsight, Sierk gained extensive project knowledge with regards to obstacle assessments and CNS safeguarding studies at airports. Through international projects, e.g. for the airports of Accra, Dubai, Malta, Nice, Montego Bay and Singapore as well as for various wind energy and project planning companies, he acquired a wide range of experience.

Prior to joining airsight, Sierk worked for a German airline as a flight operations engineer with a special focus on aircraft performance as well as aircraft weight and balance. Furthermore, he supported the airline’s flight crew training department and conducted pilot trainings as part of the pilot’s type rating.
