Question 802Navigation General

70% to pass

ECDIS must be able to perform all of the following EXCEPT _______________.

A transform a local datum to the WGS-'84 datum
B convert "graphical coordinates" to "display coordinates"
C determine magnetic compass deviation
D determine true bearing and distance between two geographical points
AI Explanation

The correct answer is C) determine magnetic compass deviation. ECDIS (Electronic Chart Display and Information System) is primarily used for navigation and does not have the capability to determine magnetic compass deviation. Magnetic compass deviation is typically determined by a separate system, such as a compass deviation table or a separate compass compensation process. ECDIS is responsible for other functions, such as transforming local datums to the WGS-84 datum, converting between graphical and display coordinates, and determining true bearings and distances between geographical points, but it does not handle magnetic compass deviation.
