SART

1. Please write the acronym SART in full.

a) It informs survivors that assistance may be nearby.

b) It informs survivors when the battery's charge condition has weakened.

c) It informs survivors when the SART switches off

d) It informs survivors that a nearly vessel is signalling on DSC.

3. How many pieces of SART must a ship of 5000 tons gross tonnage be provided with?

a) 1 b) 2 c) 3 d) 6

4. In which frequency band does a search and rescue transponder operate?

a) 3 GHz. b) 9 GHz c) S-band d) 406 MHz.

5. At what point does a SART begin transmitting?

a) It immediately begins emission when placed in the "on" position.

b) It must be manually activated.

c) If it has been placed in the "on" position, it will respond when it has been interrogated by a 9-GHz radar signal.

d) If it has been placed in the "on" position, it will begin transmitting immediately

upon detecting that it is in water.

6. How can rescue personnel detect that a SART is transmitting in the immediate

vicinity?

a) The SART's blips on the PPI will begin arching and eventually become concentric circles.

b) The DSC unit will react to the SART's signal and respond with the two-tone autoalarm.

c) The SART can provide an approximate location to within a two nautical mile radius, per IMO standards.

d) The SART signal appears as a target which comes and goes; the effect of heavy swells on a SART.

7. How can a SART's effective range be maximized?

a) The SART should be placed in water immediately upon activation.

b) The SART should be held as high as possible.

c) Switch the SART to the "high" power position.

d) If possible, the SART should be mounted horizontally so that its signal matches that of the searching radar signal.

8. What is the required number of hours that a SART's battery must be able to operate in the standby mode?

a) Eight (8) hours. b) Three (3) days. c) Four (4) days.d) Forty-eight (48) hours.

9.What conditions will normally cause a SART to operate in the active mode?

a) It will respond only to interrogation by 9-GHz radar signals.

b) A SART will normally respond to interrogation from a searching vessel's radar if

the radar antenna is at least 15 meters high.

c) A SART will normally respond to interrogation from a searching aircraft's radar if

the radar's output power is at least 10,000 watts and the aircraft is at a height of

3000 feet and within 30 nautical miles.

d) All of the above

10. Which one of the following statements concerning vessels that are required to carry only one SART is true?

a) Vessels between 300-500 gross tons are only required to have one SART.

b) This unit should be secured in a cabinet below deck until needed.

c) Passenger vessels are only required to have one SART.

d) If the vessel is more than 500 gross tons, the SART must be kept with the EPIRB for rapid deployment

11. How many pieces of SART must a ship of 400 tons gross tonnage be provided with?

a) 1 b) 2 c) 3d) 6

12. Which one of the following equipment does not transmit locating signals?

a) SARTs. b) Survival craft VHF transceivers. c) Category I EPIRBs.d) 406 MHz EPIRBs.

13. In which frequency band does a search and rescue transponder operate?

a) 3 GHz.b) 9 GHz. c) CH70.d) 406 MHz.

14. Which shipboard equipment will detect a signal from a SART?

a) 3 cm Radar. b) A DSC receiver. c) 10 cm Radar d) The Autoalarm

15. What does a SART signal sound or look like?

a) It transmits "SOS" and the vessel's name and position in slow speed Morse Code.

b) It will appear on a radar unit's PPI as a line of dots radiating outward with the innermost dot indicating the SART's position.

c) It will appear on a radar unit's PPI as a line of dots radiating outward with the outermost dot indicating the SART's position.

d) None of the above.

16. Which one of the following would most likely prevent a SART's signal from being detected?

a) Signal absorption by the ionosphere.

b) Heavy sea swells.

c) The rescue personnel were monitoring the 10-cm radar.

d) The rescue personnel were monitoring the 3-cm radar.

17. Which one of the following statements concerning SARTs is false?

a) Its battery must be capable of operating the SART in the standby mode for at least 96 hours.

b) Its signal is transmitted with vertical polarization to match that of the searching radar equipment.

c) A SART will respond to an interrogating radar signal even under heavy swell conditions.

d) A SART provides a visual or audible signal that informs survivors that assistance may be nearby.

18. Which one of the following equipment is the primary source of generating a locating signal?

a) DSC only. b) DSC and EPIRB. c) SART and DSC. d) EPIRB and SART.

19. Which one of the following statements concerning testing and maintenance of SARTs is true?

a) An at-sea GMDSS maintainer is not able to test a SART as it is hermetically sealed.

b) Testing a SART should be performed only in controlled environment as a test

signal may be misinterpreted as a genuine distress situation.

c) A SART's battery must be replaced within ninety (90) days after the expiration date imprinted on the unit.

d) All of the above.

20. Why should SART testing and maintenance be kept to a minimum?

a) A test signal may interfere with proper and safe navigation.

b) Testing the SART places an inordinate drain on its battery.

c) Possibility of misinterpretation as a genuine distress situation.

d) All of the above.

21. Which one of the following items is not the responsibility of the GMDSS Radio Operator?

a) Inspecting and cleaning the SART's container, and clearing the immediate storage

area of any debris or obstacles.

b) Measuring the SART's transmitted frequency.

c) Placing the SART in the test mode and verifying that the nearby PPI shows concentric circles.

d) Ensuring the SART’s batteries are replaced before their expiration date.

22. Which one of the following would not be a normal function when testing or performing maintenance on a SART?

a) The GMDSS Radio Operator may conduct 9-GHz voice communications with nearby vessels to coordinate SART testing.

b) The GMDSS Radio Operator should inspect the SART's container for apparent damage.

c) The GMDSS Radio Operator should inspect the battery's expiration.

d) The GMDSS Radio Operator should conduct a brief test using the vessel's radar.

23. Why is it important to limit the duration of testing a SART?

a) Excessive testing causes "burn in" on the vessel's radar PPI.

b) Testing a SART should be performed only in controlled environment as a test

signal may be misinterpreted as a genuine distress situation.

c) To prevent overheating, a SART requires sufficient ventilation which is significantly reduced when the SART is being tested.

d) If another SART is testing at the same time, the two signals will cause damage to the unit that transmitted them.
