How far must radar and surveillance antennas be positioned from fueling operations to prevent ignition?

• A. 150 feet
• B. 300 feet
• C. 500 feet
• D. 1,000 feet

Answer: (B)

The correct distance for radar and surveillance antennas to be situated away from fueling operations is 300 feet. This guideline is established to prevent potential ignition sources around sensitive areas where flammable materials are present.

The reason for this specific distance relates to safety protocols designed to minimize the risk of an ignition incident in an environment where vapors from aviation fuel can accumulate. Antennas can emit electromagnetic energy, which, if too close to fuel vapors, could ignite them, presenting a significant hazard near fueling operations.

By setting the operational boundary at 300 feet, it provides a buffer that accounts for various factors including wind patterns and the potential for vapor spread. Therefore, maintaining this distance is a critical preventive measure in aviation fuel safety practices, ensuring that radar and surveillance operations do not inadvertently contribute to ignition risks in fueling areas.
