Question: 1 / 1030

What is the primary purpose of a fuel tank sump?

To measure the amount of fuel

To collect and drain water and dirt accumulations

A fuel tank sump is designed to act as a collection point for any water or dirt that may enter the fuel tank. This is important because water and dirt can damage the aircraft's fuel system and result in engine failure.

Option A, measuring the amount of fuel, is not the primary purpose of a fuel tank sump as there are other methods and instruments for measuring fuel levels.

Option C, regulating the temperature of the fuel, is typically done through the use of a fuel heater or heat-exchanger and is not the primary purpose of a fuel tank sump.

Option D, preventing fuel leakage, is not the primary purpose of a fuel tank sump as it is primarily designed to collect and drain water and dirt, not contain fuel.
