Question 1 of 27070

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

🔍 Key Concepts

• IMO ECDIS performance standards – what tasks ECDIS is specifically designed and required to do • Difference between charting/navigation computations and shipboard instrument calibration • Role of WGS‑84 (World Geodetic System 1984) in modern electronic charts

💭 Think About

• Ask yourself: Which option describes something normally done by a chart/navigation system versus something done by a separate instrument or table on the bridge? • Think about which tasks require position and chart data (an ECDIS specialty) and which task requires knowing the ship’s magnetic characteristics and compass errors. • For each option, imagine what data ECDIS actually has: chart database, GPS position, datums, bearings/ranges on the screen. Which one would it not naturally have enough information to compute?

✅ Before You Answer

• Verify which functions are clearly related to chart projections and coordinate systems (a core ECDIS function). • Identify which option deals with geodetic datums like WGS‑84 (definitely within ECDIS/charting capability). • Check which option involves magnetic compass error or deviation, and consider whether this is normally determined by ECDIS or by separate compass adjustment methods.

Question 1 of 27070

determine magnetic compass deviation

convert "graphical coordinates" to "display coordinates"

determine true bearing and distance between two geographical points

transform a local datum to the WGS-'84 datum
