Which device is used to determine solid contamination in aircraft fuels?

• A. The Contaminated Fuel Detector Model AEL MK III is a portable field unit to determine solid contamination in aircraft fuels.
• B. A portable field unit to determine water content in aircraft fuels.
• C. A device to measure vapor pressure in aircraft fuels.
• D. A device to measure fuel color.

Answer: (A)

Solid contamination means particulate matter in fuel—rust, debris, or metal particles—that can clog filters and damage engine components. Detecting this type of impurity needs a device designed to assess particulates in a fuel sample, ideally in the field so you can make quick fueling decisions. The Contaminated Fuel Detector Model AEL MK III is specifically built as a portable field instrument to determine solid contamination in aircraft fuels, so it directly addresses this need. Because its purpose is to identify solids, it’s the best choice for this question. Other options measure things like water content, vapor pressure, or fuel color. These measurements don’t reveal solid particles, and a fuel can appear acceptable by those metrics even when solids are present.
