Question: 1 / 400

How do SARTs operate when interrogated by a radar?

Emit a single beep

Give audio/visual alarms

SARTs, or Search and Rescue Transponders, are devices designed to assist in search and rescue operations. When a radar system interrogates a SART, the device responds by transmitting a series of dots on the radar display. This response produces both audio and visual signals, alerting the search and rescue personnel to the location of the distress signal.

The audio alarms are intended to draw attention to the device's signal, while the visual alarms—displayed as a series of dots on a radar screen—allow rescuers to accurately locate the SART's position. This dual-response mechanism enhances the effectiveness of SARTs in emergency situations, making them vital for ensuring the safety of individuals in distress at sea. By providing both types of alarms, SARTs improve the chances of a successful rescue.
