What is the required distance for radar antennas from fueling operations?

• A. 100 feet
• B. 250 feet
• C. 500 feet
• D. 1,000 feet

Answer: (C)

The required distance for radar antennas from fueling operations being 500 feet is based on safety protocols established to minimize the risk of ignition from radar emissions. Radar systems emit microwave radiation, which can potentially cause sparks near flammable materials like aviation fuel. Maintaining a distance of 500 feet ensures that any radar interference is kept well away from areas where fueling operations take place, significantly reducing the likelihood of an accident or fire.

This standard also aligns with guidelines set forth by aviation safety regulatory bodies, which prioritize the safety of fueling operations in proximity to any sources of ignition. By adhering to this distance, airport operations can safely manage the heightened risks associated with using radar technology around flammable substances.

Other distances, such as 100 feet, 250 feet, or 1,000 feet, would either be insufficient to mitigate risks or unnecessarily restrictive beyond what is deemed necessary based on established safety research and regulations.
