Which mode represents the normal operation of AIS?

• A. Continuous and Autonomous mode
• B. Intermittent mode
• C. Standby mode
• D. Manual mode

Answer: (A)

The continuous and autonomous mode of AIS (Automatic Identification System) represents its normal operation because it allows vessels to transmit and receive information automatically without the need for manual input. In this mode, ships continuously send out their position, course, speed, and other navigational information at regular intervals, typically every few seconds to a few minutes, depending on the vessel's speed and conditions. This continuous stream of data enhances vessel-to-vessel and vessel-to-shore communication, significantly improving maritime safety and situational awareness. Other modes like intermittent mode would imply limited or sporadic transmission, which does not align with the objective of AIS functioning, while standby mode indicates that the system would not actively transmit data until reactivated. Manual mode relies on operator input to transmit data, which is not the intended design for AIS, as it aims to function autonomously to ensure consistent and reliable tracking of maritime traffic.
