Which of the following best describes an 'incursion' at an airport?

An incursion at an airport is best described as a situation involving ground vehicles, persons, or objects that creates a collision hazard. This definition aligns with the established terminology in aviation safety, where an incursion refers to any unauthorized presence on a runway or taxiway that poses a risk to aircraft operating in those areas.

The key aspect of this definition is the focus on ground operations and the potential for conflicting movements that can compromise safety. For example, if a ground vehicle inadvertently enters a runway during takeoff or landing operations, this presents a clear hazard to aircraft.

Understanding this definition is crucial for airport personnel, as it helps in recognizing and mitigating risks that could lead to dangerous incidents on the ramp or taxiway areas, thus ensuring the safety of all operations at the airport.
