The OLS represent the lower limit of the blocks of protected airspace around an aerodrome. They form a set of 3 dimensional surfaces which extend upwards and outwards from the runways encompassing the critical airspace utilised by air traffic.

Obstacle Limitation SURFACES Transitional Surface - A surface along side of the strip and part of the side of the approach Lower edge along the side of the approach along the length of the strip Elevation lower edge - equal to side of approach and equal to the nearest point of the center of the runway or its extension Slope 14.3%

OLS comprise of two sets of surfaces: Obstacle free surfaces (OFS) and Obstacle evaluation surfaces (OES). They have distinct purposes and are applied based: on the type of runway, Aeroplane Design Group (ADG) and the flight procedures available for that runway.

2023年10月27日 · The International Civil Aviation Organization (ICAO) has proposed new obstacle limitation surfaces (OLS) which are planned to be applicable from November 2028; the CAA has launched a consultation with UK aviation stakeholders so that they may relay their concerns to ICAO.

What is Aerodrome Safeguarding? Airspace around the aerodrome by ensuring that no buildings or structures cause danger to aircraft either in the air or on the ground. This is achieved through an assessment of the Obstacle Limitation Surfaces (OLS) (see section 5.1).

Obstacle Limitation Surfaces (OLS) The OLS represents the lower limit of the blocks of protected airspace around an aerodrome. It is a complex set of 3‐dimensional surfaces, which extend upwards and outwards from the runway(s) encompassing Safeguarding Advice …

2025年3月10日 · The introduction of new OLS surfaces will help with the operational assessment and establishment will address these points. The new OLS surfaces will become applicable in 2030. The required work to update AMC / GM and CAP168 will commence in 2025 with the aim for adoption well in advance of the applicability date, therefore mitigating the ...

Annex 14 Obstacle Limitation Surfaces (OLS) particular to a runway and its intended use. In ideal circumstances all the ICAO Annex 14 Obstacle Limitation Surfaces (OLS) will be free from obstacles, but when a surface is infringed, any safety measures required by the RSA CAA will have regard to: a.

All aerodromes in the Bahamas have to comply with OLS standards and meet PANS-OPS requirements. Equipment and installations required for air navigation purposes are to be of minimum practicable mass and height, frangible designed and mounted, and sited in such a manner as to reduce the hazard to aircraft to a minimum.

What are the Obstacle Limitation Surfaces (OLS)? The OLS completely surround the airport and generally extend out to 15km, however this can vary. They are designed to protect aircraft from obstacles when manoeuvring on the ground, taking off, landing or …
