In flight, what impact does a clogged fuel filter typically have?

A clogged fuel filter significantly reduces fuel flow to the engine. The primary purpose of a fuel filter is to prevent contaminants and debris from entering the fuel system. When the filter becomes clogged, it restricts the amount of fuel that can pass through it, leading to a decreased fuel flow to the engine.

This reduction in fuel flow can have serious consequences for engine performance, such as reduced power output, potential engine misfires, or even engine failure if the flow is significantly compromised. Proper fuel flow is essential for maintaining engine efficiency and performance during operation. Therefore, selecting the correct option reflects an understanding of how a clogged fuel filter can directly impact the fuel metering system and overall engine performance in flight.
