Which components are provided to enable connection of a Primary Air Supply Pack (PASP)?

• A. Pneumatic hose and mounting bracket
• B. Electrical connector and relay
• C. Quick disconnect and gauge
• D. Quick disconnect and valve

Answer: (D)

The ability to connect a Primary Air Supply Pack relies on two key pieces: a quick-disconnect coupling and a valve. The quick-disconnect lets you mate the PASP to the aircraft’s air line quickly and without tools, providing a secure, leak-tight connection when attached. The valve gives you control over the airflow—allowing you to shut off or regulate the air supply as needed, which is essential for safe connection, maintenance, and operation. Other options may include hoses, brackets, gauges, or electrical components, but they don’t provide both a fast, tool-free connection and an isolating/control device together.
