🔍 Key Concepts

• Difference between GMDSS Operator and GMDSS Maintainer licenses and what each is authorized to do • Rules for at-sea maintenance option and how many qualified maintainers are required on board • Who may be responsible for both distress communications and equipment maintenance under GMDSS

💭 Think About

• Look at which choices confuse the roles of operator and maintainer. Does GMDSS allow one person to hold both roles if properly licensed? • For the at-sea maintenance option, think carefully: is there a specific minimum number of maintainers required, or just that at least one qualified person must be available? • Which statements incorrectly expand maintainer authority to people who only hold an operator license, or unnecessarily prohibit someone from holding more than one responsibility?

✅ Before You Answer

• Check which license is specifically required to perform or supervise technical repairs/maintenance of GMDSS equipment (Maintainer vs. Operator). • Verify whether regulations require one or two GMDSS maintainers when the at-sea maintenance option is selected. • Confirm whether the same person, if properly licensed, may be designated both for distress radiocommunications and for maintenance responsibilities, or if the rules forbid this.
