7-A-039: SART: Activation & Survival Craft Operations

7-39F1: What indication is given to the personnel in a survival craft of the approach of SAR craft?

The SART may provide a visual or audible indication of interrogation by a 3-cm radar.

The Satellite EPIRB will change its strobe light pattern to indicate radar interrogation.

The SART informs survivors when the SART switches to the "standby" mode.

The AIS SART will alarm to indicate that SAR craft with radars are getting close.



7-39F2: Which of the following would most likely not prevent a SART signal from being detected?

The SART was properly mounted in the lifeboat and rescue personnel were monitoring the 3-CM radar.

The rescue personnel were monitoring the 3-CM radar and the SART was mounted improperly in the lifeboat.

The SART was mounted improperly in the survival craft and rescue personnel were monitoring the 10-CM radar.

The rescue personnel were monitoring the 10-CM radar and the SART was properly mounted in the lifeboat.



7-39F3: How can a SART's detection and effective range be maximized?

The SART should be held or mounted as high as possible and in a vertical position.

The SART should be placed in water immediately so it will begin transmitting.

Switch the SART into the "high" power position.

If possible, the SART should be mounted horizontally so that its signal matches that of the searching radar signal.



7-39F4: Which statement is NOT true regarding the SART?

This is a 6 GHz transponder capable of being received by a vessel's X-band navigational radar system.

Responds to interrogations by a vessel's X-Band radar and transmits a signal.

This is a 9 GHz transponder capable of being received by a vessel's X-band navigational radar system.

Transmits a distinctive 12-blip signal for easy recognition.



7-39F5: At what point does a SART begin transmitting?

If it has been placed in the "on" position, it will respond when it has been interrogated by a 9-GHz radar signal.

It immediately begins radiating when placed in the "on" position.

It must be manually activated or water activated before radiating.

If it has been placed in the "on" position, it will begin transmitting immediately upon detecting that it is in water.



7-39F6: A SART's signal cannot be detected:

By a search vessel's 10 cm Radar.

In poor visibility, or at night.

In heavy seas.

By a search vessel's 3 cm Radar.
