FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

Question: 1 / 1030

What function does the absolute pressure regulator perform in the pneumatic power system?

Regulates the compressor inlet air to provide a stabilized source of air for the compressor

The absolute pressure regulator is responsible for regulating the compressor inlet air to provide a stabilized source of air for the compressor. This is important in maintaining a consistent flow of air, which is necessary for the proper functioning of pneumatic systems. Option B is incorrect because it refers to controlling the output pressure of the compressor, which is not the function of the pressure regulator. Option C is incorrect because regulating the temperature of the air entering the compressor is the function of a separate component called the air dryer. Option D is incorrect because filtering the air is the function of an air filter, not the pressure regulator.
