What indication do personnel in a survival craft receive from the approach of SAR craft?

The reason that the chosen answer is accurate lies in the functionality of the Search and Rescue Transponder (SART). When a SART is activated and detects radar signals from a Search and Rescue (SAR) craft, it transmits specific responses to indicate to personnel in a survival craft that help is nearby. This is typically through visual signals displayed on radar screens, which can include indications such as a series of blips that help rescuers identify the location of survivors.

The SART is designed to provide a clear and effective means of communication during rescue operations, as it specifically responds to radar interrogations. This connection between the SART’s operations and its response to SAR craft is crucial for ensuring that survivors can be located quickly and efficiently.

In contrast, other devices like the Satellite EPIRB and the AIS SART serve different purposes. The Satellite EPIRB does not change its strobe light pattern specifically to indicate SAR craft; it transmits distress signals. Similarly, the SART in standby mode does not provide any direct indication to survivors about the approach of SAR craft, and the AIS SART does not alarm in relation to the proximity of SAR craft in the same way as the SART that responds to radar interrogation does.
