### How far from the parking apron must the tanks be placed if the ABFDS is used to resupply the R-14C fuel servicing module?

• A.

75 feet.

• B.

100 feet.

• C.

125 feet.

• D.

150 feet.

B. 100 feet.
Explanation
The tanks must be placed 100 feet away from the parking apron when using the ABFDS to resupply the R-14C fuel servicing module. This distance is necessary to ensure the safety of the fueling operation and to prevent any potential accidents or hazards. Placing the tanks at this distance allows for sufficient space and reduces the risk of any fuel spills or fires reaching the aircraft or the parking apron area.

• A.

110Â°F.

• B.

120Â°F.

• C.

130Â°F.

• D.

140Â°F.

B. 120Â°F.
Explanation
The engine of the R-14C fuel servicing module must reach a temperature of 120Â°F during idle before you can increase the throttle setting. This indicates that the engine needs to warm up sufficiently before it can handle a higher throttle setting, ensuring optimal performance and preventing any potential damage or malfunction.

Rate this question:

• 9.

### What is the minimum operating oil pressure for the R-14C fuel servicing module at normal operating speed?

• A.

10 psi.

• B.

• D.

40 psi.

D. 40 psi.
Explanation
The minimum operating oil pressure for the R-14C fuel servicing module at normal operating speed is 40 psi. This means that the module requires a minimum oil pressure of 40 pounds per square inch in order to function properly. Operating the module at a lower oil pressure could result in inefficient or ineffective fuel servicing.

Rate this question:

• 10.

### When placed in the low mobility position, what is the maximum ramp angle the R-14C can negotiate?

• A.

10Â°.

• B.

15Â°.

• C.

20Â°.

• D.

25Â°.

B. 15Â°.
Explanation
The R-14C can negotiate a maximum ramp angle of 15Â° when placed in the low mobility position. This means that the vehicle can safely climb a slope with an incline of up to 15 degrees without any issues. Going beyond this angle may result in the vehicle losing traction or even tipping over. Therefore, 15Â° is the highest ramp angle that the R-14C can handle in this specific position.

• C.

To fill the pumpâ€™s priming unit.

• D.

To pump fuel from operating tanks.

A. To fill the engine tank.
Explanation
The purpose of the float valve on the R-22 pump assembly is to fill the engine tank. This valve regulates the flow of fuel into the tank, ensuring that it is filled to the appropriate level. By controlling the fuel supply, the float valve helps to maintain the engine's performance and prevent any fuel-related issues.

Rate this question:

• 12.

### When setting up the R-22, how many sections of 25-foot hose should be used to connect the R-22 to the FFU-15E?

• A.

2.

• B.

3.

• C.

4.

• D.

5.

B. 3.
Explanation
To properly set up the R-22, three sections of 25-foot hose should be used to connect it to the FFU-15E. This ensures that there is enough length to connect the two devices effectively and allows for flexibility in positioning and placement. Using fewer sections of hose may result in a limited range of motion or difficulty in connecting the devices. Using more sections of hose may lead to unnecessary excess length and potential tangling or tripping hazards. Therefore, three sections of 25-foot hose is the optimal choice for setting up the R-22.

Rate this question:

• 13.

### After starting the R-22, how long should the engine be allowed to idle before increasing the throttle setting?

• A.

1 minute.

• B.

3 minute.

• C.

5 minute.

• D.

6 minute.

C. 5 minute.
Explanation
The engine of the R-22 helicopter should be allowed to idle for 5 minutes before increasing the throttle setting. This is important to ensure that the engine reaches the optimal operating temperature and all the necessary systems are functioning correctly. Allowing the engine to idle for this duration helps in preventing any potential damage or issues that could arise from abrupt throttle changes. It also allows for a smoother transition when increasing the throttle setting.

25 feet in front of and centered on the dike wall.

• B.

50 feet in front of the dike wall.

• C.

25 feet in front of the dike wall.

• D.

50 feet in front of and centered on the dike wall.

A. 25 feet in front of and centered on the dike wall.
Explanation
The FFU-15E should be placed 25 feet in front of and centered on the dike wall. This positioning ensures that the FFU-15E is at a safe distance from the dike wall while still being able to effectively perform its function. Placing it 50 feet in front of the dike wall would create unnecessary distance and potentially reduce its effectiveness.
