What should inspectors look for regarding airport lighting?

Inspectors should focus on ensuring that airport lighting is operable and free of any interference, such as vegetation or foreign objects. This is crucial because proper function and visibility of airport lighting are essential for safety during aircraft operations, particularly during landing and takeoff phases. When lighting is obstructed, it can create hazards for pilots attempting to navigate the airport environment.

While using high-intensity bulbs, directional lighting, and visibility through flashing lights can also play a role in overall lighting effectiveness, they do not directly address the operational status and potential obstructions that can affect the functionality of the lighting system. Therefore, ensuring that the lights are operational and clear from interference is the most critical aspect that inspectors must prioritize.
