GMDSS. FCC Test 23 – Online Maritime Tests

1/10

What indication is given to the personnel of survival craft of the approach of another vessel?

The SART will provide a visual or audible indication of interrogation by a 3-cm radar.
The VHF portable radio will emit an audible alarm signal on 156.525 MHz.
The VHF portable will provide a visual indication.
The Satellite EPIRB will emit an audible signal.

Which statement is true regarding distress communications under GMDSS?

All of these.
The Rescue Coordination Center (RCC) is responsible for controlling a search and rescue operation and will also coordinate the distress traffic relating to the incident.
Distress communications by NBDP should be in the ARQ mode when in communications with the Coast Guard or other coast stations.
The Rescue Coordination Center may appoint another station to coordinate distress traffic relating to the incident.

GMDSS vessels equipped for A2, A3 or A4 must maintain a continuous DSC watch on 2187.5 kHz.

When directed to do so by a cognizant rescue authority.
Only in areas beyond Inmarsat coverage.
At all times when underway.
Only outside of areas covered by VHF-DSC.

How many HF frequencies are available for DSC distress related calls?

Two
Four
Five
One

Which action is the most appropriate action for a GMDSS radio Operator to take in a distress situation where immediate help is needed, but the vessel is not sinking nor needs to be abandoned?

Switch off EPIRB and SART manually.
Notify the RCC (Rescue Coordination Center) through VHF FM on channel 13.
Transmit distress call by HF/MF/VHF DSC or Inmarsat.
Transmit distress call by activating the radiotelegraph automatic alarm signal.

DSC is used primarily to:

Receive weather warnings, navigational notices and other marine safety information.
Report ship's position to search-and-rescue authorities via satellite.
Provide routine communications with the ship owner.
Transmit and receive distress, urgent and safety alerts to and from other ships and shore stations via radio.

What is the purpose of the SART's audible tone alarm?

It informs survivors that assistance may be nearby.
It informs survivors when the battery's charge condition has weakened.
It informs survivors when the SART switches to the 'standby' mode.
It informs survivors that a nearby vessel is signaling on DSC.

Which of the following steps should be taken, if possible, when the vessel must be abandoned because of a distress situation?

Place the SART and EPIRB in the 'on' position and secure them to the survival craft.
Alert the U.S. Coast Guard by using the survival craft's portable INMARSAT unit.
Program the SART and EPIRB to transmit the vessel's location and situation.
No additional steps are needed as the SART and EPIRB will both automatically float free and operate properly.

How many frequencies are available under GMDSS for DSC distress-related calls?

When operating in coastal waters (sea area A1), a GMDSS-equipped vessel must:

Maintain a continuous DSC watch on VHF channel 16.
Maintain a continuous aural watch on 2182 kHz.
Maintain a continuous DSC watch on VHF channel 70.
Maintain a continuous DSC watch on 8514.5 kHz.
