Ensure trucks and trailers used for transporting aircraft potable water are parked in what area?

• A. Public
• B. Restricted
• C. Open
• D. Private

Answer: (B)

Potable water for aircraft is a safety-critical, contamination-sensitive operation, so access to the equipment and its vehicles must be tightly controlled. Parking trucks and trailers in a restricted area ensures that only authorized and trained personnel can approach, service, and move the water supply, which helps maintain water quality, traceability, and security. It also supports proper sanitation checks, sampling, and documentation.

In contrast, public or open areas expose the equipment to unauthorized access, potential tampering, or contamination, and a private area may not provide the same level of security controls and oversight. For these reasons, the correct parking area is a restricted area.
