A. GMDSS utilizes automated systems and satellite technology to improve emergency communications for the world’s shipping industry.
B. It is intended to automate and improve existing digital selective calling procedures and techniques.
C. It is intended to provide more effective but lower cost commercial communications.
D. It is intended to provide compulsory vessels with a collision avoidance system when they are operating in waters that are also occupied by non-compulsory vessels.
Which of the following is a functional or carriage requirement for compulsory vessels?
A. A compulsory vessel must carry at least two (2) FCC licensed GMDSS Radio Operators in all sea areas as well as a GMDSS Maintainer in sea areas A3 & A4.
B. A compulsory vessel must satisfy certain equipment carriage requirements based on the intended sea area of operation.
C. A compulsory vessel must be able to transmit and respond to Distress alerts and carry only one (1) FCC licensed GMDSS Radio Operator in sea areas A1 & A2.
Which statement is true regarding a vessel equipped with GMDSS equipment that will remain in Sea Area A1 at all times?
A. The vessel must be provided with a radio installation capable of initiating the transmission of ship-to-shore Distress alerting from the position from which the ship is normally navigated.
B. VHF DSC alerting may be the sole means of Distress alerting.
C. HF or MF DSC may satisfy the equipment requirement.
D. HF SSB with 2182 kHz automatic alarm generator may satisfy the equipment requirement.
A. After silencing an alarm all displays and/or printouts are read, monitoring all required frequencies in the proper mode, notifying the Master of any Distress alerts.
B. Monitoring all required frequencies in the proper mode, setting the DSC scanner to 2 MHz, 4 MHZ and 8 MHz for ships in the vicinity, notifying the Master of any Distress alerts.
C. Notifying the Master of any Distress alerts, setting the DSC scanner to 2 MHz, 4 MHZ and 8 MHz for ships in the vicinity, monitoring all required frequencies in the proper mode.
D. Setting the DSC scanner only to the mandatory 2 MHz & 8 MHz, maintain continuous watch on 2182.0 kHz or 4125.0 kHz, notify the Master of any Distress traffic heard.
Which statement is true regarding the receipt and acknowledgement of Distress alerts by ship stations?
A. Ship stations in receipt of a Distress alert should acknowledge it immediately to assist the coast station in responding to the Distress alert.
B. A ship station that receives a Distress alert must, as soon as possible, inform the Master or person responsible for the ship of the contents of the Distress alert.
C. Ship stations that receive a Distress alert from a vessel in their vicinity must immediately send a DSC relay to inform the RCC.
D. Alerts concerning navigational hazards are second only to Safety traffic.
What actions should the GMDSS radio operator take prior to any potential Distress situation?
A. Create a table or chart of all the DSC coast stations that might be used during the vessel’s itinerary.
B. All of these answers are good operational practice and should be consistently done.
C. Prepare a detailed Distress message file on both satellite & MF-HF SITOR (NBDP) equipment containing all information needed in a Distress so it will be available for last-minute editing.
D. Ensure all LES choices are correct and then updated properly as the vessel transits different SAR jurisdictions.
How is mutual interference on 518 kHz among NAVTEX stations avoided?
A. Transmissions scheduled on a time-sharing basis, power limited and station assignment codes are geographically separated.
B. All stations transmit at the same time but stations are limited to daytime operation only to reduce the radius of propagation.
C. Transmitter power is limited, station assignment codes are not shared by other NAVAREAS and stations alternate between daytime and nighttime operations.
D. Station codes are not shared by other NAVAREAS, transmissions scheduled on a time-sharing basis and power is limited.
If the Inmarsat-C terminal is inoperative but the vessel remains within NAVTEX coverage -- which of the following message categories should not be disabled by the GMDSS Radio Operator?
A. Navigational warnings, meteorological warnings and metrological forecasts.
B. Search and Rescue information, navigational warnings and other electronic navaid messages.
C. Search and Rescue information, Meteorological warnings and ice reports.
D. Meteorological warnings, Search and Rescue information and Navigational warnings.
