What is the preliminary action for low fuel pressure?

The correct action in the case of low fuel pressure is to execute the Pel maneuver. This response is critical because it allows for the assessment of the situation and the prevention of potential engine failure due to fuel starvation. The Pel procedure involves specific steps to regain control over the engine's fuel system, ensuring that adequate fuel pressure is restored or that alternative measures are prepared if necessary.

Taking immediate measures like cutting engine power or turning off the boost pump could lead to more severe issues, such as complete engine failure, as they would disrupt the flow of fuel even further. Increasing throttle in the event of low fuel pressure may seem like a way to compensate for the situation, but it could cause additional strain on the fuel system and lead to a higher risk of engine malfunction.

Therefore, executing the Pel maneuver is the most appropriate and effective preliminary action for addressing low fuel pressure, prioritizing safety and system integrity.
