4-52. The function of the dual cursor position control is to 1. determine the position of the cursor in range only 2. determine the position of the cursor in azimuth and range 3. apply a signal to control the direction in which the transducer will radiate 4. apply bearing and range information to the pilot’s bearing and range indicator IN ANSWERING QUESTION 4-53, REFER TO FIGURE 4-19 IN THE TEXTBOOK. 4-53. 4-54. 4-55. 4-56. Which of the following components is NOT mounted on the front panel of the sonar transmitter? 1. 2. 3. 4. The FAULT indicator CURSOR POSITION switch POWER circuit breaker STANDBY indicator SDC has which of the following functions? 1. Provides a digital readout of target range, speed, and depth 2. Processes and displays LOFAR, DIFAR, and CASS sonobuoy signals on the sonar set’s CRT 3. Provides a digital readout of target size 4. Processes and displays LOFAR, DIFAR, and ASPECT sonobuoy signals on the sonar set’s CRT Which of the following modes classified as an operational 1. PASSIVE 2. TEST 3. RANGE 4. ECHO-RANGING Which of the following modes is NOT mode? is NOT classified as a recording mode? 1. BT 2. TEST 3. COMM 4. ASPECT 4-57. 4-58. 4-59. 4-60. 4-61. When the sonar set ECHO-RANGING mode, target bearings by is operating in the set presents scanning (a) what number of sectors of (b) what size each? 1. (a) Four (b) 90° 2. (a) Eight (b) 90° 3. (a) Four (b) 45° 4. (a) Eight (b) 45° The sonar operator can determine target bearing by noting the position of the target with respect to what part of the sector in which the target appears? 1. Top 2. Center 3. Bottom 4. Edge The sonar operator can determine the nature of a target by noting which of the following features of the target? 1. Display outlines only 2. Audio quality and display outline 3. Range 4. Closeness to other targets What information is displayed on the RANGE RATE-KNOTS meter? 1. Range and speed of the target within the cursor circle 2. Range and speed of all targets 3. Only the range of the target within the cursor circle 4. Only the speed of the target within the cursor circle While operating in the PASSIVE mode, the operator notices a noise spoke on the CRT. What does the spoke indicate? 1. The CRT is burned 2. The hydrophore is malfunctioning 3. An underwater sound source is present 4. A nearby sonar set is operating in the PASSIVE mode 28
