Maritime Safety Information transmissions?
4209.5 kHz using FEC mode
4209.5 kHz using ARQ mode
4125.0 kHz using simplex mode
4125.0 kHz using FEC mode
Answer: 4209.5 kHz using FEC mode
●● Which information determines if a NAVTEX message is to be
rejected?
The second letter (from A to Z) in the header indicating the type of
message.
Transmitter identity (numerals from 1 to 26 identifying transmitting
station within the NAVAREA).
The Answerback of the receiving station has not been entered in the
NAVTEX receiver.
Only messages having a serial number 00 are rejected.
Answer: The second letter (from A to Z) in the header indicating the type
of message
,●● What type of station would be assigned the call sign WAB2174?
Tug boat
Container ship
Passenger ship
Bulk Tanker
Answer: tug boat
●● Which of these cannot happen when a paper model NAVTEX
receiver runs out of paper?
The unit is unable to print messages and all subsequent MSI broadcasts
may be missed until the paper is replaced.
The system will automatically change from receiving MSI by NAVTEX
to receiving it by SafetyNETTM so that no messages will be lost.
It may give off either an audible and/or visual alarm.
MSI messages may be missed because the unit cannot print them out.
Answer: The system will automatically change from receiving MSI by
NAVTEX to receiving it by SafetyNETTM so that no messages will be
lost.
●● What is defined as an area, excluding sea areas A1 and A2, within
the coverage of an Inmarsat geostationary satellite in which continuous
alerting is available?
Ocean Area Regions AOR-E, AOR-W, POR or IOR
,Sea Area A3
Sea Area A4
Coastal and Inland Waters
Answer: Sea Area A3
●● What determines whether a NAVTEX receiver prints a particular
type of message content from a programmed NAVTEX station?
The serial number and type of message have already been received but
additional printouts are generated to ensure receipt aboard the vessel.
The subject indicator has been programmed for rejection by the operator
but the message contains a priority override print command.
The transmitting station ID covering your area has been programmed for
rejection by the operator or has not been previously received.
The serial number and type of message has not been previously received
or the subject indicator has not been programmed for rejection
Answer: The serial number and type of message has not been previously
received or the subject indicator has not been programmed for rejection.
●● Which of the following regions lie outside Sea Areas A1, A2, and
A3?
Sea Areas only apply to Inmarsat footprint areas.
Sea Area A3-I Inmarsat coverage and Sea Area A3-S HF SITOR
(NBDP) coverage.
Sea Area A4
, There are no additional Sea Areas.
Answer: Sea Area A4
●● What statement is true regarding the additional equipment carriage
requirement imposed for the survival craft of vessels over 500 gross
tons?
Additional carriage of two radio equipped lifeboats aft.
A second radar transponder is required.
Four additional portable VHF radios are required.
The ability to communicate in all modes with any shore station.
Answer: A second radar transponder is required.
●● Which statement is true regarding a vessel equipped with GMDSS
equipment that will remain in Sea Area A1 at all times?
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.
VHF DSC alerting may be the sole means of Distress alerting.
HF or MF DSC may satisfy the equipment requirement.
HF SSB with 2182 kHz automatic alarm generator may satisfy the
equipment requirement.
Answer: 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.
