Question

Which data must ECDIS be able to record at one-minute intervals?

1) Position
2) Speed
3) Course
4) Heading

Answer 1

ECDIS is required to record position, speed, course, and heading at one-minute intervals for navigation safety and incident investigations.

Step-by-step explanation:

ECDIS, which stands for Electronic Chart Display and Information System, must be able to record the following data at one-minute intervals:

1. Position: ECDIS records the latitude and longitude of the vessel to accurately plot its location on the electronic chart.
2. Speed: ECDIS records the vessel's speed through water or ground speed to calculate ETA (Estimated Time of Arrival) and plan safe navigation.
3. Course: ECDIS records the vessel's course or heading, which represents the direction that the vessel is moving in. It helps the navigator to steer the vessel along the intended route.

The Electronic Chart Display and Information System (ECDIS) is required to record specific navigational data to ensure safety at sea. According to the International Maritime Organization (IMO) guidelines, the data that ECDIS must be capable of recording at one-minute intervals includes position, speed, course, and heading. This functionality is crucial for the accurate tracking of a vessel's movement and to assist in navigation decisions, particularly in the case of an investigation following a maritime incident.

These data points are crucial for safe and efficient navigation as they provide real-time information about the vessel's position, speed, and direction.
