Where is the indicator for electric boost pump operation located?

• A. A white light above the boost pump switch
• B. On the center console
• C. On the overhead panel
• D. On the flight deck door

Answer: (D)

The key idea here is visibility of a critical system status at the moment you’re entering the cockpit. The electric boost pump indicator is placed on the flight deck door so both pilots can see it at a glance as they enter or stand at the doorway. This location lets you confirm pump operation quickly during preflight, start, and engine operation without needing to search through panels or divert attention from flight tasks. It supports immediate awareness of whether the boost pumps are energized, which is important for maintaining proper fuel pressure during start and flight. Other locations would require looking away from the entry path and scanning panels, which slows recognition and could lead to missed or delayed status awareness.
