What system will automatically shut off components if a leak is detected?

• A. LDI
• B. Overheat protection
• C. Fuel purge
• D. Fire suppression

Answer: (A)

The Leak Detection Interlock (LDI) is designed to automatically isolate a leak by shutting off the affected fuel paths. When a leak is detected in the fuel system, the LDI triggers and closes the corresponding fuel shutoff valves, isolating the faulty component (such as a engine fuel line or related feed) to prevent further fuel loss and reduce the risk of a fire. This automatic isolation is exactly what the question describes. Other systems handle other issues—overheat protection manages temperature, fuel purge clears fuel lines, and fire suppression fights a fire after it starts—not automatically isolating a leaking line.
