Which condition best describes the readiness check for the JBD during daily maintenance?

• A. It should be free of leaks and properly aligned
• B. It must be repainted a fresh color
• C. It should be moved to a different location on deck
• D. It should be connected to a separate power source

Answer: (A)

The most important thing checked in daily readiness for the JBD is that it is free of hydraulic leaks and properly aligned. A leak indicates the hydraulic system isn’t maintaining pressure, which can lead to loss of deflector control and unsafe launches. Proper alignment ensures the jet blast is directed correctly away from personnel and equipment and that the deflector will interact with the aircraft and catapult system as designed. Repainting is cosmetic and won’t affect performance, moving the JBD would undermine the fixed, calibrated setup, and using a separate power source isn’t typical for daily readiness since the JBD relies on the ship’s hydraulic/power system and must operate as designed.
