Which statement accurately describes the Ordered calculation method in Set and Drift?

• A. Computed - Real time updates by comparing ship heading and speed with course and SOG
• B. Computed - Updates at designated intervals of 3, 6, and 15 minutes using entered course and speed
• C. Real time updates by comparing heading and speed with course and SOG
• D. Set and drift calculated at designated intervals of 3, 6, and 15 minutes using entered course and speed

Answer: (D)

Ordered calculation method means you forecast set and drift at fixed time steps using the course and speed you have entered. The system does not continuously react to changes in your heading; instead, it uses the pre-entered course and speed to project, at the specified intervals, how the current will affect your track. The usual intervals—3, 6, and 15 minutes—define when these set and drift values are calculated and then presented for planning or navigation. This contrasts with a real-time computed approach that continuously updates by comparing the ship’s heading and speed with the course and SOG.
