the required competencies are increasingly being examined by these following external parties
EXCEPT: - ANS Pilots
Data are logged in the ECDIS, the following information may be logged EXCEPT: - ANS Engine
RPM
Displaying SEC Information conforms to which performance standard? - ANS The selected
safety contour is displayed with greater emphasis than other contour
During route planning and route monitoring, the following SENC information available for
display should be subdivided into the following categories EXCEPT : - ANS North up Display
During you navigation and your ECDIS gives an alarm, what is the possible cause of the alarm? -
ANS When the specified limit for deviation from the planned route is exceeded
ECDIS display must consist of the following EXCEPT? - ANS Magnetic compass deviation
ECDIS must be able to perform all the following EXCEPT: - ANS Determine magnetic compass
deviation
ECDIS provides many benefits for route planning , a few of which of the following EXCEPT: -

, For the optimum situational awareness, what must be always recognized by navigators for
objects presented when using ECDIS? - ANS The level of display
For vessel fitted with only one ECDIS, What shall be used as the primary means of navigation ? -

crossing a line in the chart you set in relation to the actual draft of the ship in a voyage
planning? - ANS Safety contour
