Which data must ECDIS be able to record at one-minute intervals?
AI Explanation
The correct answer is B) Course made good history.
ECDIS (Electronic Chart Display and Information System) is required to record the course made good history at one-minute intervals. This requirement is specified in the International Maritime Organization (IMO) Performance Standards for ECDIS, which outline the mandatory data that ECDIS systems must be able to record for navigational purposes.
The other options are incorrect because they are not part of the mandatory data recording requirements for ECDIS. Shaft RPM (A) and speed through the water (C) are not required to be recorded by ECDIS, while estimated time of arrival (D) is not a real-time navigational data point that ECDIS needs to record at one-minute intervals.
