Which component is designed to prevent foreign objects from entering the system?

• A. Inlet screen
• B. Compressor bleed air filter
• C. Exhaust silencer
• D. Fuel nozzle

Answer: (B)

The part designed to keep foreign objects out of the system is the bleed air filter. It sits in the compressor bleed air line and removes dirt, dust, and small debris from the air that is bled off the compressor before it goes to pneumatic systems such as anti-ice, starting, or environmental control. By filtering this air, it prevents debris from entering those subsystems and potentially causing wear, blockage, or actuator damage. The inlet screen does block large objects at the engine intake, but the question is about preventing foreign objects from entering the system through the bleed air path. The exhaust silencer handles noise, and the fuel nozzle has a completely different role in fuel delivery, so they don’t fit the intended function.
