Aerodrome Obstacle Surveys: Ensuring Safe Flight Operations

​

An aerodrome obstacle survey is an important aspect of ensuring safe flight operations. The survey is conducted to identify any obstacles, such as buildings, towers, or trees, that may pose a threat to aircraft flying in the vicinity of an airport. This information is then used to develop obstacle limitation surfaces (OLS) which outline the safe flying areas around an airport.

​

The purpose of an aerodrome obstacle survey is to identify any potential hazards that could impede the safe take-off, landing, or movement of aircraft. This includes any obstacles that may be located within the approach and departure paths of an airport, as well as those that may be located on the airport grounds. The survey also takes into account any potential hazards that may be caused by changes in the surrounding terrain, such as new construction or the removal of trees.

​

The aerodrome obstacle survey is typically conducted by a team of aviation professionals, including engineers, surveyors, and pilots. The team will use a variety of tools and techniques to gather data, such as aerial photography, laser scanning, and ground-based measurements. They will also consult with local authorities and organizations to gather information on any planned developments or construction in the area.

​

Once the data has been collected and analyzed, the team will develop obstacle limitation surfaces (OLS) which outline the safe flying areas around an airport. These surfaces are used by pilots and air traffic controllers to ensure that aircraft remain at a safe distance from obstacles during take-off, landing, and ground movement. The OLS also helps to identify areas where obstacles need to be removed or relocated to improve safety.

​

Aerodrome obstacle surveys are typically conducted on a regular basis, such as every 5 years, to ensure that the information used to develop the OLS remains accurate and up-to-date. This is important as new construction and development can change the obstacle environment around an airport.

Advantages of Aerodrome Obstacle Surveys for Safe Flight Operations:

​

• Enhanced Safety: Aerodrome obstacle surveys identify potential obstacles like buildings or trees that could be dangerous for aircraft. This helps ensure safe take-offs, landings, and movements around airports.

• Accurate Data: The surveys use advanced tools like aerial photography and laser scanning to collect precise information about obstacles. This accurate data helps pilots and air traffic controllers make informed decisions.

• Improved Planning: The surveys consider future developments in the area, like new constructions. This helps airports plan and manage their surroundings to maintain safe flight paths.

• Constant Monitoring: Regular surveys, typically every 5 years, keep the obstacle information updated. This ongoing monitoring ensures that pilots have the latest data for safe operations.

• Collaborative Approach: Experts from various fields, including engineers, surveyors, and pilots, work together during the surveys. This collaborative effort ensures a comprehensive and accurate assessment of obstacles.

​

In conclusion, aerodrome obstacle surveys play a crucial role in ensuring safe flight operations at airports. By identifying potential hazards and developing obstacle limitation surfaces, pilots and air traffic controllers can ensure that aircraft remain at a safe distance from obstacles during take-off, landing, and ground movement. Regular updates to the OLS are also essential in order to keep the information accurate and up-to-date.
