What is the definition of a "controlled burn" at airports?

A controlled burn at airports refers to a planned fire aimed at managing vegetation. This practice is utilized to promote the health of surrounding ecosystems and to prevent the build-up of debris that could pose a risk to airport operations. By intentionally setting a fire under specific weather conditions and with careful monitoring, airport personnel can help maintain vegetation in a controlled manner, ensuring that it does not interfere with flight operations or pose a fire hazard. This practice is also crucial for habitat restoration and reducing the risk of uncontrolled wildfires that could impact airport safety.

In contrast, other scenarios described, such as a fire started to clear runways or a fire ignited accidentally, do not align with the controlled and intentional nature of a controlled burn. Similarly, simulated fire drills for training purposes are conducted for different reasons, focusing on personnel preparedness rather than vegetation management. Thus, the definition that fits best is the planned fire for managing vegetation, which plays a vital role in airport safety and environmental stewardship.
