What legend appears on the EICAS display when FPS experiences a fault?

• A. FPS FAIL
• B. FPS WARN
• C. FPS ERROR
• D. FPS INOP

Answer: (A)

EICAS uses a status word with the subsystem name to signal its condition. When a fault is detected in a system, the legend shows the word that denotes a fault, not just a warning or an inoperative state. For the Fuel Pump System, a fault condition is conveyed as “FPS FAIL.” That clearly tells the crew there’s a failure in the fuel pump system and it needs attention, beyond a mere advisory or a simple indication that the system is not operating for non-fault reasons. A warning would imply a caution but not a confirmed failure, and terms like “FPS INOP” or “FPS ERROR” are not the standard EICAS labels for this situation.
