EMERGENCY PROCEDURE

1. Please write the acronym SAR in full.

1. In the GMDSS, by what means and in which frequency bands should a ship station in distress alert other ships in its vicinity?

1. In radiotelephony, how many times shall the safety signal SECURITE be repeated on the announcement of a safety message?

a) Three times b) Two times c) Three times at most d) Six times

4. In the GMDSS, what does the urgency signal consist of?

a) Of the word PAN

1. Which are the preferred frequencies in radiotelephony for on scene communications?

a) 121.5 MHz and 2045 kHz

b) Ch 13 (156.650 MHz) and 2023 kHz

c) Ch 70 (156.525 MHz) and 2174.5 kHz

d) Ch 16 (156.800 MHz) and 2182 kHz

6. Which frequency in the medium frequency band is used for distress and safety traffic by radiotelephony?

a) 2182 kHz

b) 6090 kHz

c) 518 kHz

d) 2614 kHz

7. Which measures shall be taken by a ship station in receipt of a distress alert transmitted using digital selective calling?

a) The ship station shall set watch on the radiotelephony distress and safety traffic frequency associated with the distress and safety calling frequency on which the distress alert was received

b) The ship station shall remain listening on the frequency on which the distress alert was received

c) The ship station shall repeat the distress alert on the frequency on which it was received in order to alert several more ships

d) The ship station shall, in every case, set watch on the frequencies 2182 kHz and 121.5 MHz

8. In a mobile unit, who shall authorize the transmission of an urgency call format or an urgency signal?

a) The owner of the mobile unit

b) The master of the vessel after consultation with the owner

c) The master or the person responsible for the mobile unit

d) The master or the person responsible for the mobile unit after consultation with the coast station responsible

9. In the GMDSS, what does the distress signal consist of?

a) - SOS b) - PAN PAN c) -MAYDAY e) -QDC

10. In the GMDSS, who is responsible for the control of on-scene communications?

a) The mobile unit in distress

b) The mobile unit in distress and the unit co-ordinating the search and rescue operations

c) The unit coordinating the search and rescue operations

d) The mobile unit in distress or the unit co-ordinating the search and rescue operations

11. What is the fundamental purpose for imposing radio silence?

a) To ensure that interference to proprietary communications is minimized.

b) To ensure that only voice communications can be effected on the distress communications frequency or channel.

c) To ensure that a distressed vessel will have a "window" twice each hour for transmitting routine messages.

d) To ensure that interference on a particular frequency or channel to communications concerning emergency traffic is minimized.

12. When can routine communications be resumed on a frequency or channel on which radio silence has been imposed?

a) Routine communications can resume after determining that the frequency or channel appears to be no longer in use.

b) Routine communications can resume after determining that geographic distance from the distress situation will prohibit any other signal from interfering with emergency communications.

c) Routine communications can resume after the Rescue Coordination Center transmits a message on the frequency or channel being used for emergency communications stating that such traffic has concluded.

d) Routine communications can resume if, in the master's opinion, communications on that frequency or channel will interfere with emergency communications.

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

a) Alert the U.S. Coast Guard by using the survival craft's portable INMARSAT unit.

b) Program the SART and EPIRB to transmit the vessel's location and situation.

c) Place the SART and EPIRB in the "on" position and secure them to the survival craft.

d) No additional steps are needed as the SART and EPIRB will both automatically float free and operate properly.

14. Who is responsible for transmitting a message stating that distress communications have ceased?

a) The Rescue Coordination Center (RCC) controlling the distress communications.

b) The vessel providing the initial communications with the distressed vessel.

c) The Coast Radio Station (CRS) that was first contacted concerning the distress situation.

d) No formal message must be transmitted as long as no distress-related communications have occurred after reasonable time.

15. What is meant by the term "radio silence"?

a) Stations not directly involved with the on-going distress communications may not transmit on the distress frequency or channel.

b) Stations remaining off the air to safeguard proprietary information.

c) Two three-minute silent periods, at the top and bottom of every hour, that provide a transmitting "window" for distressed vessels to transmit distress alerts.

d) Communications on a distress frequency or channel is banned for 24 hours following the cessation of the distress traffic.

16. How is a normal working condition restored on a narrow band direct printing (NBDP) frequency on which radio silence had been imposed?

a) The Rescue Coordination Center (RCC) that imposed the radio silence must transmit a narrow band direct printing message on the distress frequency stating "SILENCE FINI".

b) The Coast Earth Station (CES) that imposed the radio silence must transmit a NBDP message on the distress frequency stating "SILENCE FINI".

c) The Public Correspondence Station (PCS) that imposed the radio silence must transmit a NBDP message on the distress frequency stating "SILENCE FINI".

d) The High Seas Service (HSS) that imposed the radio silence must transmit a NBDP message on the distress frequency stating "SILENCE FINI".

17. How is a normal working condition restored on a voice frequency or channel on which radio silence had been imposed?

a) The Rescue Coordination Center (RCC) that imposed the radio silence must transmit a voice message on the distress frequency stating "SILENCE FINI".

b) The Coast Earth Station (CES) that imposed the radio silence must transmit a voice message on the distress frequency stating "SILENCE FINI".

c) The Public Correspondence Station (PCS) that imposed the radio silence must transmit a voice message on the distress frequency stating "SILENCE FINI".

d) The High Seas Service (HSS) that imposed the radio silence must transmit a voice message on the distress frequency stating "SILENCE FINI".

18. What is usually the first step for a GMDSS Radio Operator to take when initiating a distress priority message via INMARSAT?

a) By dialing the correct code on the telephone remote unit.

b) By pressing a “distress button” on the equipment.

c) By contacting the CES operator and announcing a distress condition is in existence.

d) By contacting the CES operator using the radiotelephone distress procedure “Mayday”... etc.

Worldwide Navigational Warning Service

The Worldwide Navigational Warning Service (WWNWS) established through joint efforts of the International Hydrographic Organization (IHO) and International Maritime Organization (IMO) is a coordinated global service for the promulgation of navigational warnings.

Navigational warnings are designed to give the mariner early information of important incidents which may constitute a danger to navigation. Many navigational warnings are of temporary nature, but others remain in force for several weeks and may be succeeded Notices to Mariners (NM).

Navigational warnings are of three types: NAVAREA warnings, Coastal warnings and Local warnings. The language in both NAVAREA and Coastal warnings is invariably English, although warnings may additionally be transmitted in one or more of the official languages of the United Nations.
