What does a flag of fixed length at the end of the AIS vector indicate?

• A. The target is at a standstill
• B. The target is changing speed
• C. The target is turning
• D. The target is lost

Answer: (C)

The flag of fixed length at the end of the AIS vector is used to signify that the target is changing course or direction. This visual representation is crucial for navigators in understanding the current status and movements of maritime vessels. When the AIS vector displays a fixed length, it indicates that while the vessel is moving, it is not adjusting its speed; instead, it is altering its direction or heading. This specific indicator helps mariners anticipate the movement of nearby vessels and make informed navigational decisions, especially in busy waterways where changes in course can significantly affect vessel interactions. The understanding of these visual cues is essential for effective navigation and collision avoidance in maritime operations. The other options do not accurately represent the meaning of a fixed-length flag at the end of the AIS vector.
