  1. What is the function of a SART (Search and Rescue Transponder)?

    Answer: To respond to X-band radar pulses by creating a distinctive pattern on a radar screen to aid rescuers in locating survivors

    A SART activates when it receives an X-band radar pulse and transmits a series of blips that appear on the searching vessel's radar, creating a clear trail leading to the survivor's position.

  2. What does SAR datum mean?

    Answer: The most probable position of a missing vessel or person, accounting for drift and leeway

    SAR datum is the calculated most probable position of the search object, derived from last known position, time elapsed, drift due to current, and leeway due to wind.

  3. Which immersion suit feature is most critical for survival in cold water?

    Answer: Thermal insulation to prevent hypothermia

    Thermal insulation is the most critical feature of an immersion suit because hypothermia kills within minutes to hours in cold water; the suit slows heat loss dramatically.

  4. What is the purpose of a pyrotechnic distress signal (flare)?

    Answer: To signal distress and attract the attention of rescuers visually

    Pyrotechnic distress signals (parachute flares, handheld flares, and orange smoke) provide a highly visible visual distress signal to attract the attention of passing vessels and aircraft.

  5. A Coast Guard Sector coordinates SAR efforts in its area. What is the first step in a SAR response?

    Answer: Evaluate the alert to determine the nature and urgency of the distress situation

    The first step in a SAR response is evaluating the alert to determine if it is a confirmed distress, classifying the urgency, and planning the most appropriate response before deploying assets.

  6. What is the duty watch requirement for VHF Channel 16 on commercial vessels?

    Answer: Maintain a continuous watch while underway

    FCC and USCG regulations require commercial vessels subject to the Bridge-to-Bridge Communications Act to maintain a continuous watch on VHF Channel 16 at all times while underway.
