7-A-041: SART: Frequency & Operations
7-41F1:
Which of the following statements concerning testing and maintenance of SARTs is true?
Testing a SART should be done in a consistent manner & location to ensure a baseline history of proper results.
Testing of the SART should never be done in port to prevent interference to other vessel's radars.
A SART's battery must be replaced within ninety (90) days after the expiration date imprinted on the unit.
An at-sea GMDSS maintainer is not be able to test a SART because it is hermetically sealed.
7-41F2:
Why is it important to limit the duration of testing a SART?
Testing in port or even at sea may cause interference to other radars or a test signal may be misinterpreted as a genuine Distress situation.
Excessive testing causes "burn in" on the vessel's radar display.
To prevent overheating, a SART requires sufficient ventilation that is significantly reduced when the SART is being tested.
If another SART is testing at the same time, the two signals will cause damage to the unit that transmitted them.
7-41F3:
What statement is true regarding tests and maintenance that could be provided for the SART?
Extreme care should be exercised because testing of the SART may be received by other vessels, may be interpreted as a Distress condition, or it may interfere with other vessels' safe navigation.
Full verification within manufacturer's specifications by the on-board maintainer would be a requirement for all vessels in the A3 & A4 sea areas using measuring equipment to generate 9 GHz signals.
Battery should be replaced within the 90 day grace period following the manufacturer's expiration date shown on the SART and the SART should only be tested at-sea to reduce interference to other vessels.
Battery should be replaced with a new one before the manufacturer's expiration date shown on the SART and the SART should only be tested in port to reduce interference to other vessels.
7-41F4:
Why should functional testing of a SART be minimized?
Potential interference with safe navigation, possible misinterpretation of an actual Distress, minimizes draining the battery.
Potential interference with safe navigation, notifying other vessels of an actual Distress and minimize power consumption.
Minimize power consumption of the battery and only test at sea to reduce potential interference or confusion.
Possibility of misinterpretation by other vessels as a Distress situation and only test in port to prevent potential interference with safe navigation or at-sea vessels.
7-41F5:
Which is not a valid maintenance and testing function for a SART?
Operational test with several vessels to determine effective transmitting range.
Inspection of container for apparent damage.
Inspect battery expiration date and the lanyard condition.
Brief operational test utilizing own ship's radar.
7-41F6:
The SART is required to have a sufficient battery capacity to operate in the stand-by mode for what period of time?
Four days
Three days
Eight hours
Forty-eight hours
