The FUEL 1 PRESS LOW caution indicates what condition?

The FUEL 1 PRESS LOW caution indicates what condition?

• A. Engine Oil Pressure Is Low
• B. Fuel Pressure On The #1 Engine Is High
• C. Fuel Pressure On The #1 Engine Is Low (Below 9 Psi)
• D. Fuel Flow Is Restricted

Answer: (C)

The warning is telling you that the fuel pressure feeding engine number 1 has dropped below the minimum acceptable level. In this helicopter, a low fuel pressure condition is triggered when engine 1’s fuel pressure falls to about 9 psi or lower, which is why the indication specifies “low” with the noted threshold. This is different from oil pressure or from a flow-restricted condition, so the other possibilities don’t fit what this alert is showing. A low fuel pressure reading points to a potential fuel pump problem, a blockage, or other fuel delivery issue to that engine, and it can threaten engine power if not addressed. In flight, you’d monitor the engine parameters closely, consider available remedies like crossfeed to balance the supply, and prepare for a safe landing if the condition persists.
