FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

Question: 1 / 1030

What type of fuel quantity indicating system uses several probes in each tank?

Mechanical

Float-type

Pressure-based

Electronic

Electronic fuel quantity indicating systems use several probes in each tank to measure and display the fuel level. Mechanical fuel quantity systems rely on moving parts and can be prone to wear and tear. Float-type systems use a float that moves along with the fuel level, but they are less accurate and reliable. Pressure-based systems use the change in pressure to determine the fuel level, but they can be affected by changes in temperature or air pressure. Electronic systems, on the other hand, use sensors to directly measure the fuel level and provide precise and accurate readings. Therefore, the correct answer is electronic.
