The ICAO Twelfth Air Navigation Conference (2012) and the 38th Session of the ICAO Assembly (2013) called for a comprehensive review of the obstacle limitation surfaces in Annex 14 — Aerodromes, Volume I — Aerodrome Design and Operations, and the development of guidance for conducting aeronautical studies to assess permissible penetrations to the surfaces. To this end, ICAO has carried out extensive work and detailed studies over the past six years and is now proposing significant changes and improvements to the OLS. to the joint International Civil Aviation Organization (ICAO)/Airports Council International (ACI) Obstacle Limitation Surfaces Symposium (OLSS 2021) aims at increasing international awareness of the proposed changes and obtaining feedback from States and industry prior to ICAO adoption for global applicability.
