Which pair of alternate control locations correspond to Zone 20 and Zone 21 respectively?

• A. Jet Shop and Flight Deck Control & FWD and AFT of the island
• B. The Bridge and Pri-fly for both
• C. Jet Shop and Jet Shop
• D. Flight Deck Control and AFT of the island and The Bridge

Answer: (A)

Alternate control locations give you a backup way to operate the AFFF transfer station if the primary control area is unavailable. Each zone corresponds to a specific station where you can command the system. For Zone 20 and Zone 21, the appropriate pair is Jet Shop for Zone 20 and Flight Deck Control for Zone 21, with those stations located forward and aft of the island to provide access from different parts of the ship. This setup ensures you can maintain control even if one area is blocked by something like fire or smoke. The other options fail because they either use the same location for two zones, or assign control to locations that don’t correspond to Zone 20 and Zone 21.
