Which of the following is NOT a component of a fire protection system in transport category aircraft?

1. Fire handle

2. Extinguishing agent

3. Heat detectors

4. Fuel management system

The correct answer is: Fuel management system

In transport category aircraft, a fire protection system is designed to detect and control fires that may occur within the aircraft. This system typically includes several key components: - The fire handle is part of the fire suppression system, allowing pilots to activate the discharge of extinguishing agents to combat fires in specified areas, such as the engine or cargo compartments. - Extinguishing agents are the materials used to put out the fire, such as halon or other fire suppressants. These agents are critical in stopping the fire's progression and minimizing damage. - Heat detectors play a vital role in early fire detection. They are strategically placed within the aircraft to sense elevated temperatures indicating a potential fire, allowing for a timely response. In contrast, the fuel management system is not a component of the fire protection system. Instead, it is responsible for managing the fuel supply and distribution to the engines and may include fuel tanks, pumps, valves, and associated controls. While proper fuel management is crucial for safe aircraft operation and can help prevent fuel-related fires, it does not play a direct role in fire detection or suppression, distinguishing it from the other components of the fire protection system.
