What is the minimum distance that ground-traffic radar antennas should be from fueling operations?

• A. 50 ft
• B. 75 ft
• C. 100 ft
• D. 150 ft

Answer: (C)

The minimum distance of 100 feet for ground-traffic radar antennas from fueling operations is established to ensure safety in areas where flammable vapors and liquids are present. This distance acts as a precaution to mitigate the risk of ignition from potential sparks or electromagnetic interferences generated by radar equipment.

Maintaining this separation is critical, as radar antennas can produce radiofrequency emissions that, while typically non-hazardous, may pose a risk in the presence of explosive atmospheres created during fueling. The 100-foot minimum provides a buffer that is considered safe for both personnel and equipment, contributing to overall operational safety at airports.

This 100-foot guideline is consistent with safety standards and best practices in aviation fueling operations, aiming to protect the site and personnel from the hazards associated with fuel handling and storage.
