New Obstacle Limitation Surfaces: Obstacle Free Surfaces and Obstacle Evaluation Surfaces
This course provides an overview of the upcoming changes of the Obstacle Limitation Surfaces (OLS) specified in ICAO Annex 14 Vol. I (Aerodromes).
The ICAO Annex 14 Obstacle Limitation Surfaces (OLS) have origins in the 1950s and were established to ensure the safety of aeroplane operations. History shows that the OLS become penetrated by new obstacles world-wide, and it becomes more difficult to protect the surfaces against new obstructions. The reasons are manifold and include unclear objectives of the OLS, inconsistencies between ICAO Annex 14, Annex 6, and PANS OPS requirements as well as unclear adequacy between the obstacle requirements of the surfaces and the complex impact of obstacles on the operations.
To address the deficiencies of the current OLS, the ICAO Obstacle Limitation Surfaces Task Force (OLSTF) proposes to replace current OLS by a new twofold concept of Obstacle Free Surfaces (OFS) and Obstacle Evaluation Surfaces (OES). Furthermore, a new code systematic, the aeroplane design groups (ADG), for the design of the OFS and OES is foreseen.
The objective of this training course is to provide an introduction of the new concept and new surfaces. The new ADG as well as the OFS and OES are presented. The surface dimensions as well as obstacle limitation requirements are discussed.
The course is designed for all persons involved in this complex subject, including aerodrome, Civil Aviation Authority personnel, or project developers.
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
Dipl.-Ing. Malte Karger
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).
Dipl.-Ing. Sierk Törl
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 and Montego Bay 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.
