ABOVE QUESTIONS WITH ANSWERS 


Question Number. 1. When the moisture separator is purged in a pneumatic system, it dumps.
Option A. just the moisture trap.
Option B. the whole system.
Option C. the system between compressor and regulator valve.
Correct Answer is. just the moisture trap.
Explanation. Jeppesen A&P Technician Airframe Textbook Page 8-54. CAIPs AL/3-22.


Question Number. 2. The pneumatic system pump is a.
Option A. centrifugal type.
Option B. rotor vane type.
Option C. piston type.
Correct Answer is. piston type.
Explanation. Jeppesen A&P Technician Airframe Textbook Page 8-56, Although smaller systems may have avane type.


Question Number. 3. In a pneumatic system, the maintainer valve will be fitted in supply lines to.
Option A. essential equipment.
Option B. all equipment.
Option C. non-essential equipment.
Correct Answer is. non-essential equipment.
Explanation. CAIPs AL/3-22. Maintainer valves work in same way as those in hydraulic systems (hence the reference). Although they protect the flow to the essential systems, they do so by being situated in the non-essential lines, and closing off if the pressure drops.


Question Number. 4. High pressure pneumatic source is a.
