GMDSS Exam Questions and Answers

What is the GMDSS meaning?

The GMDSS meaning refers to the Global Maritime Distress and Safety System, an internationally agreed-upon set of safety procedures, types of equipment, and communication protocols used to increase safety and make it easier to rescue distressed ships, boats, and aircraft.

What are the GMDSS requirements for Sea Area A1?

GMDSS requirements for Sea Area A1 include at least one VHF radio capable of DSC (Digital Selective Calling) on channel 70, a NAVTEX receiver, a SART (Search and Rescue Transponder), and an EPIRB (Emergency Position Indicating Radio Beacon).

What is the weekly test of GMDSS equipment?

The weekly test of GMDSS equipment involves testing the DSC facilities of VHF, MF, and HF radios by means of a test call to a coast station, ensuring the proper functioning of the reserve source of energy, and checking the survival craft two-way VHF equipment.

How do I get my GMDSS GOC certification?

To obtain a GMDSS GOC (General Operator's Certificate), you must complete an approved GMDSS course (typically 8-10 days), pass the written and practical GMDSS exam administered by an authorized body (like the FCC or AMERC), and meet age and medical fitness requirements.

What is a GMDSS log book?

A GMDSS log book is a mandatory record where all radio communications related to distress, urgency, and safety must be recorded. It also includes records of daily, weekly, and monthly equipment tests, battery maintenance, and significant incidents.

What is the difference between GMDSS GOC and ROC?

The GMDSS GOC (General Operator's Certificate) allows operation in all sea areas (A1, A2, A3, A4), while the ROC (Restricted Operator's Certificate) is limited to Sea Area A1 only. GOC covers MF/HF and satellite equipment, whereas ROC focuses primarily on VHF GMDSS operations.

What equipment is required for the GMDSS system?

The GMDSS system requires various equipment depending on the sea area, including VHF radios with DSC, MF/HF radios, Inmarsat satellite terminals, NAVTEX receivers, EPIRBs, SARTs, and portable two-way VHF radios for survival craft.

How often must GMDSS batteries be tested?

GMDSS batteries must undergo a daily on-load and off-load voltage check. Additionally, a full capacity test should be performed annually to ensure they can supply the required power for the specified duration in an emergency.

What does the FCC GMDSS license cover?

The FCC GMDSS license (GMDSS Radio Operator's License) authorizes the holder to operate and maintain GMDSS radio equipment on compulsory equipped vessels. It confirms the holder understands distress frequencies, GMDSS procedures, and equipment operation.

Is a GMDSS simulator useful for training?

Yes, a GMDSS simulator is highly effective for training as it allows candidates to practice distress alerts, DSC calls, and equipment handling in a safe, controlled environment without transmitting false alarms on actual emergency frequencies.
