2-10. Which of the following is a proper wind- 

 shift entry in column 13 of an MF1-10 

 form? 



1. WSHFT 1530 



2. WSHFT 1530E 



3. WSHFT 153 0Z 



4. WSHFT 1530 GMT 



2-11. If, at the time of the observation, there 

 was a 15-knot true wind from the west 

 with peak gusts of 22 knots, data for 

 columns 12, 13, and 14 of the MF1-11 will 

 be entered, respectively, as 



1. 090 15G 22 



2. 270 15 G22 



3. 15 270 Q22 



4. G22 15 090 



2-12. How may the true wind direction and speed 

 be determined for entry on the MF1-11 

 form? 



1. By estimating only 



2. By using the CP-264U computer only 



3. By using the plotting board method 

 only 



4. By using the plotting board and the 

 CP-264U computer or estimating 



2-16. Refer to Table 3-2 in your text. If the 

 pointer of the wind speed indicator of 

 the AN/PMQ-3( ) does NOT rest on zero 

 when the turbine is stationary, what 

 should be done? 



1. The switch should be checked 



2. The indicator should be replaced 



3. The transmitter should be replaced 



4. An adjustment should be made with the 

 zero adjustment control screw 



2-17. The wind speed transmitter of the 



AN/PMQ-3( ) should be lubricated once 

 every 



1 . month 



2. two months 



3. three months 



4. six months 



Learning Objective: Relative to 

 components of the Wind Measuring 

 Set AN/UMQ-5( ), indicate minimum 

 acceptable combinations, operational 

 features, model differences, and 

 applicable maintenance procedures. 



2-13. Wind recorder charts are changed at 



intermediate times as necessary to pre- 

 vent loss of record and always on the 

 first day of the 



1. week at 0000 GMT 



2. month at 0000 GMT 



3. week at 0000 LST 



4. month at 0000 LST 



Learning Objective: Recognize oper- 

 ating and maintenance practices 

 associated with the AN/PMQ-3( ) Wind 

 Measuring Set. 



2-14. The trigger on the handle of the Wind 

 Measuring Set AN/PMQ-3( ) is used to 

 lock the 



1. vane on a given setting 



2. voltmeter on the 0- to 15-knot scale 



3. voltmeter on the 0- to 60-knot scale 



4. cylindrical turbine when the set is 

 not in use 



2-15. Damage will first occur to the pointer 

 of the AN/PMQ-3 if the range selection 

 trigger is depressed when the wind speed 

 exceeds the maximum of 



1. 16 kn 



2. 15 kn 



3. 10 kn 



4. 5 kn 



2-18. Refer to figure 3-2 (A through E) in 



your textbook. The Wind Measuring Set 

 AN/UMQ-5( ) includes which of the 

 following combinations as a minimum? 



1. A, B, D, and E 



2. A, B, and E 



3. A, C, D, and E 



4. A, C, and D 



2-19. How does the transmitter of the 



AN/UMQ-5( ) position the wind direction 

 indicator needle? 



1. The motion of the impeller drives the 

 needle directly by means of mechanical 

 couplings through links, shafts, and 

 gears 



2. The motion of the vane drives the 

 indicator needle directly by means of 

 a hydraulic coupling through a capil- 

 lary tube 



3. The motion of the vane is transmitted 

 to a synchro in the vertical support 

 and a follower synchro in the indi- 

 cator positions the needle mechan- 

 cally 



4. The motion of the impeller drives a 

 tachometer-magneto whose output is 

 measured by a voltmeter which is 

 mechanically attached to a needle in 

 the indicator
