Search and rescue locating devices
What is being checked
The inspector is checking whether radar SART or AIS-SART units are correctly stowed, in date and capable of guiding rescuers to survival craft, with officers able to configure, cross-check, test and respond to failure of the actual equipment fitted.

Answer aloud, then open the preparation point.
1What safety function does search and rescue locating devices provide?
Radar sart or ais-sart units are correctly stowed, in date and capable of guiding rescuers to survival craft.
2How is the complete function tested?
Use the manufacturer self-test, inspect casing, switch protection and accessories and verify that testing avoids false AIS or radar distress indications.
3What is its principal limitation?
Radar SART requires X-band radar interrogation and height; AIS-SART relies on AIS reception and GNSS, so their indications and limitations differ.
4What is your response if it fails?
Deploy the remaining approved device to the survival craft, maximise antenna height, use other distress signals and replace the defective unit.
5Show the latest test and operational evidence.
Link the dated record to the actual unit, test method, result, defect response and restoration; a panel lamp test alone is not sufficient where the full signal path can be tested.
Where an observation may arise
The responsible officer cannot explain safe use, limitations or failure response.
Testing does not prove the required operational function or remote indication.
Expiry or seal condition is unacceptable.
Pole, bracket or lanyard needed for deployment is missing.
Crew search for the wrong indication or use the wrong activation method.
Master's practical note
Ask how the unit will be mounted after abandonment. Testing at the bridge proves little if the pole, bracket or survival-craft deployment is not understood.
Equipment boundary and references
Equipment boundary: The approved locating-device type may be radar SART or AIS-SART. Use the fitted unit's instructions and avoid radiating a false distress target during tests.
