If both FUEL 1 PRESS LOW and FUEL 2 PRESS LOW cautions appear, what is possible? Do not make rapid collective movements.

If both FUEL 1 PRESS LOW and FUEL 2 PRESS LOW cautions appear, what is possible? Do not make rapid collective movements.

• A. Engine Surge
• B. Flameout
• C. Loss Of Hydraulic Pressure
• D. Rotor Vibration Increase

Answer: (B)

When both engines show low fuel pressure, fuel starvation is happening to both powerplants. If the fuel supply can’t reach the combustors, the engines can’t sustain combustion and will flame out. With both engines flameout, you lose power from both sides, which is the direct cause of a rapid loss of rotor torque and potential handling challenges. Engine surge is a compressor instability typically tied to air/fuel dynamics during throttle changes, not simply low fuel pressure; hydraulic pressure loss or rotor vibration increase aren’t the immediate, direct results of dual fuel starvation, though they can occur as secondary effects in more complex failure scenarios. The most plausible consequence here is engine flameout.
