Which of the following is a feature of a Fuel Dumping System?

• A. Provisions in the main tanks to ensure not all fuel is dumped
• B. Use a fuel flowmeter to see flow rate and calculate time for dump
• C. Use automatic float shutoff valves that ensure a reserve of 45 min
• D. Use electric meter to increase dump rate

Answer: (A)

The question tests how a fuel-dumping system is designed to lighted a safe operation by leaving a fuel reserve. A key feature is that there are provisions in the main tanks to prevent all fuel from being dumped, ensuring some fuel remains for safety margins, landing weight management, and to reach a divert point if needed. In practice, this means the system is arranged so it cannot completely empty the tanks—either by leaving a minimum quantity in reserve or by a control that caps how much can be dumped. The other statements describe monitoring or rate-control ideas (a flowmeter, a fixed 45-minute reserve, or an electric meter to boost dump rate) that are not universal features of fuel-dumping systems and don’t represent the core safety design.
