Read the first 6 CMRT Regulatory Compliance & Type Approval flashcards as text

  1. Under U.S. regulations, who is authorized to perform maintenance that involves opening the radar's magnetron or transmitter assembly?

    Answer: An FCC-licensed General Radiotelephone Operator (GROL) or qualified service technician

    U.S. FCC rules require that internal transmitter repairs on marine radar be performed by or under the supervision of an FCC GROL licensee.

  2. Which USCG Navigation and Vessel Inspection Circular (NVIC) provides guidance on the maintenance and testing of radar on inspected vessels?

    Answer: NVIC 01-00 (or its successor) on electronic navigation equipment maintenance

    USCG NVICs on electronic navigation equipment address maintenance intervals, testing procedures, and documentation requirements for radar aboard inspected vessels.

  3. What ITU frequency band is allocated for conventional X-band marine navigation radar in the United States?

    Answer: 9.2–9.5 GHz

    X-band marine radar operates in the 9.2–9.5 GHz frequency range as allocated by the ITU Radio Regulations and reflected in U.S. FCC rules.

  4. What ITU frequency band is used by S-band marine navigation radar?

    Answer: 2.9–3.1 GHz

    S-band marine radar operates in the 2.9–3.1 GHz range, providing longer range and better performance in rain and fog than X-band.

  5. Why must a CMRT technician consult the equipment's type-approval certificate before performing a software update on a certified marine radar?

    Answer: Unauthorized software updates can void type approval and render the equipment non-compliant with SOLAS carriage requirements

    Type approval is tied to the hardware-software configuration tested; an unapproved software version may invalidate certification and the vessel's Safety Radio Certificate.

  6. Which organization issues the international GMDSS type-approval recognized for radar systems on SOLAS vessels?

    Answer: Flag state administrations or their delegated recognized organizations (classification societies)

    Type approval for SOLAS equipment is granted by each vessel's flag state administration or a recognized organization (e.g., classification society) it delegates.
