Use of ECDIS to maintain the safety of navigation

Note: Training and assessment in the use of ECDIS is not required for those who serve
exclusively on ships not fitted with ECDIS.  This limitation shall be reflected in the endorsements
issued to the seafarer concerned	Navigation using ECDIS

Knowledge of the capability and limitations of ECDIS operations, including:

.1   a thorough understanding of Electronic Navigational Chart (ENC) data, data accuracy, presentation rules, display options and other chart data formats

.2   the dangers of over-reliance

.3   familiarity with the functions of ECDIS required by performance standards in force

Proficiency in operation, interpretation, and analysis of information obtained from ECDIS, including:

.1   use of functions that are integrated with other navigation systems in various installations, including proper functioning and adjustment to desired settings	Examination and assessment of evidence obtained from one or more of the following:

.1   approved training ship experience

.2   approved ECDIS
simulator training	Monitors information on ECDIS in a manner that contributes to safe navigation

Information obtained from ECDIS (including radar overlay and/or radar tracking functions, when fitted) is correctly interpreted and analysed, taking into account the limitations of the equipment, all connected sensors (including radar and AIS where interfaced), and prevailing circumstances and conditions

Safety of navigation is maintained through adjustments made to the ship’s course and speed through ECDIS-controlled track-keeping functions (when fitted)

Communication is clear, concise and acknowledged at all times in a seamanlike manner
