Which description matches the correct pre-flight check for the BCF extinguisher?

• A. In place, gauge in green sector
• B. In place, securely stowed with red disc showing
• C. In place
• D. Not in place

Answer: (B)

The test focuses on confirming that the fire extinguisher is ready for immediate use, which means it must be properly secured and its safety seal intact. For the BCF extinguisher, being in place and securely stowed ensures it won’t shift during flight, while the red disc showing is the tamper/seal indicator that the unit hasn’t been discharged or tampered with. Together, “in place, securely stowed with red disc showing” confirms both proper positioning and intact security, making it the best description of a correct pre-flight check. The other options don’t guarantee both the physical security and the seal status, so they don’t communication the same level of readiness.
