Introduction to New Obstacle Limitation Surfaces (OLS)
This course provides a concise technical overview of the New OLS concept, the ADG and the OFS/OES forming the basis for modern aerodrome safeguarding.
The ICAO Annex 14 Obstacle Limitation Surfaces (OLS) have their origins in the 1950s and were established to ensure the safety of aeroplane operations. History shows that the OLS are frequently penetrated by new obstacles world-wide, and it has become more difficult to protect the surfaces against new obstructions. The reasons are numerous and include unclear objectives of the OLS, inconsistencies between ICAO Annex 14, Annex 6, and PANS OPS requirements as well as a mismatch between the obstacle requirements of the surfaces and the complex impact of obstacles on the operations.
To address the deficiencies of the current OLS, a revised OLS has been adopted by ICAO in 2025. A new twofold concept, which has been developed by the Obstacle Limitation Surfaces Task Force (OLSTF), now comprises of the obstacle free surfaces (OFS) and obstacle evaluation surfaces (OES). Furthermore, a new code system, the aeroplane design groups (ADG), for the design of the OFS and OES was introduced.
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 people involved in this complex subject, including aerodrome, Civil Aviation Authority personnel, or project developers.

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).
