After power-up, what indicates a successful login on an Inmarsat-C terminal?

• A. The antenna Azimuth and Elevation controls are correctly adjusted.
• B. The terminal is enabled for routine incoming and outbound traffic.
• C. The receiver gain is properly adjusted for maximum signal.
• D. Unscheduled EGC MSI messages can no longer be received.

Answer: (B)

The indication of a successful login on an Inmarsat-C terminal is reflected by the terminal being enabled for routine incoming and outbound traffic. This means that the terminal has successfully connected to the satellite network and is ready to send and receive messages as per the operational requirements. When a terminal logs in successfully, it establishes communication with the satellite, which allows users to conduct regular operations and exchange information. This status is critical for ensuring that the vessel or user can effectively utilize the services offered by the Inmarsat network. The other options focus on operational conditions and adjustments but do not directly indicate the login status. The settings for antenna control, receiver gain adjustments, or the reception of specific messages illustrate different operational aspects but do not confirm that the terminal is logged in and ready for routine operational traffic.
