FAA AMT Airframe Practice Exam 2026 – Complete Exam Prep Guide

Pneumatic systems utilize relief valves to ensure safety and functionality. Relief valves are crucial components in pneumatic systems as they are designed to release excess pressure and prevent over pressurization, which can lead to system failure or damage. By opening at a preset pressure, relief valves help maintain the optimal pressure levels within the pneumatic system, ensuring smooth and safe operation. Compressors are responsible for generating and maintaining the pneumatic pressure, filters are used to remove contaminants from the air, and actuators are components that convert pneumatic power into mechanical motion.
