How does the searching vessel's radar interrogate a survival craft SART?

Maintain watch on VHF-FM Ch-70 for the SART's unique identifier.
The SART responds automatically when it detects the search craft or other vessels' X-Band radar signal.
Activate the IFF interrogation system.
The SART responds automatically when it detects the search craft or other vessel's 3.5 GHz radar signal.

How can a SART's effective range be maximized?

The SART should be placed in water immediately upon activation.
If possible, the SART should be mounted horizontally so that its signal matches that of the searching radar signal.
Switch the SART into the 'high' power position.
The SART should be held as high as possible.

At what point does a SART begin transmitting?

If it has been placed in the 'on' position, it will begin transmitting immediately upon detecting that it is in water.
It immediately begins radiating when placed in the 'on' position.
It must be manually activated.
If it has been placed in the 'on' position, it will respond when it has been interrogated by a 9-GHz radar signal.

In a lifeboat or liferaft, what is a method of maximizing the effectiveness of an SART?

What does a SART signal sound or look like?

It transmits 'SOS' and the vessel's name and position in slow speed Morse Code.
It will appear on a radar unit's PPI as a line of dots radiating outward with the outermost dot indicating the SART's position.
It will appear on a radar unit's PPI as a line of dots radiating outward with the innermost dot indicating the SART's position.
None of the above.

What signal is detected as originating from an SART?

The Morse code distress series S-O-S repeated three times followed by DE and the vessel's call sign.
None of these.
A line of dots on a radar screen outward from the SART's position along its line of bearing.
A line of dots on a radar screen inward from the SART's position to its own ship along its line of bearing.

What causes the SART to begin a transmission?

How can vessel personnel detect the operation of a SART in its vicinity?

A unique two-tone alarm signal heard upon the automatic un-muting of the 2182 kHz radiotelephone automatic watch receiver.
The SART signal appears as a target which comes and goes; the effect of heavy swells on an SART.
A unique radar signal consisting of a 12 dots radiating outward from a SART's position along its line of bearing.
A unique two-tone 'warbling' signal heard on VHF-FM Ch-70.

How should the signal from a Search And Rescue Radar Transponder appear on a radar display?

How can rescue personnel detect that a SART is transmitting in the immediate vicinity?

The SART signal appears as a target which comes and goes; the effect of heavy swells on a SART.
The SART can provide an approximate location to within a two nautical mile radius, per IMO standards.
The DSC unit will react to the SART's signal and respond with the two-tone auto alarm.
The SART's dots on the PPI will begin arcing and eventually become concentric circles.
