Which condition does not require replacement of filter elements on the R–19 filter separator unit?
- A.
A reading of 16 psid on the differential pressure (DP) gauge.
- B.
A reading of 22 psid on the DP gauge.
- C.
Elements that have been in use for 36 months.
- D.
Filter separator vessel performance is questionable.
Correct Answer
A. A reading of 16 psid on the differential pressure (DP) gauge.Explanation
A reading of 16 psid on the differential pressure (DP) gauge indicates that the filter elements are still functioning effectively and have not yet reached the point where they need to be replaced. The DP gauge measures the pressure difference across the filter elements, and a reading of 16 psid suggests that there is still sufficient capacity for the filter to continue operating efficiently. Therefore, there is no immediate need for replacement of the filter elements in this condition.Rate this question:

What pressure should the surge suppressor gauge on the R–20 multi-aircraft servicing unit indicate when the fueling system is not operating?
- A.
45 psi.
- B.
75 psi.
- C.
90 psi.
- D.
150 psi.
Correct Answer
C. 90 psi.Explanation
The surge suppressor gauge on the R-20 multi-aircraft servicing unit should indicate 90 psi when the fueling system is not operating. This pressure is necessary to ensure that the system is ready to operate and can handle any potential surges or fluctuations in pressure that may occur during fueling. A lower pressure may indicate a potential issue with the system, while a higher pressure may cause damage or leaks in the system. Therefore, 90 psi is the correct pressure for the surge suppressor gauge in this situation.Rate this question:

The micronic filter elements on the R–20multi-aircraft servicing unit should be replaced when the differential pressure (DP) reading exceeds
- A.
10 psid.
- B.
15 psid.
- C.
20 psid.
- D.
25 psid.
Correct Answer
B. 15 psid.Explanation
The micronic filter elements on the R-20 multi-aircraft servicing unit should be replaced when the differential pressure (DP) reading exceeds 15 psid. This means that when the pressure difference between the upstream and downstream sides of the filter reaches or exceeds 15 pounds per square inch, it is an indication that the filter is becoming clogged and is no longer effectively filtering the air. Replacing the filter at this point ensures that the unit continues to operate efficiently and maintain the desired level of filtration.Rate this question:
