157. What indication is given to the personnel in a survival craft of the approach of SAR craft?
A radar SART provides a visual or audible indication when interrogated by a 3-cm radar, signaling the proximity of SAR craft. This device responds to radar signals and alerts survivors, unlike EPIRBs which use satellites or AIS SARTs which use VHF frequencies. The SART's function is to locate survival craft and provide a clear indication of approaching rescue units.
