What alerts the pilot when the No. 1 or No. 2 fuel filter is bypassed?

• A. Fuel Filter Failure
• B. Fuel Low Pressure
• C. Fuel 1 Bypass or Fuel 2 Bypass
• D. APU Fuel Modulation

Answer: (C)

In the UH-60S, when a fuel filter becomes blocked, a bypass valve opens and the cockpit displays a specific alert to tell you exactly which filter is bypassed. This is the Fuel 1 Bypass or Fuel 2 Bypass indication. It’s designed to let fuel continue to flow around the clogged element while signaling to the crew that the corresponding filter should be serviced or replaced. This targeted annunciation is more informative than a general fuel filter failure or a low-pressure warning, and it’s not related to APU fuel modulation. So the precise alert for a bypass is what you’d expect to see.
