IMO Resolution A.817(19) - ECDIS Flashcards
The primary function of the ECDIS is to contribute to _________________________-.
safe navigation
ECDIS should be capable of displaying all chart information necessary for safe and efficient navigation originated by, and distributed on the authority of _________________________________________.
government-authorized hydrographic offices
Electronic chart display and information system (ECDIS) means a navigation information system which, with adequate back-up arrangements, can be accepted as complying with the up-to-date chart required by regulation V/20 of the 1974 SOLAS Convention, by displaying selected information from a _______________________________ with positional information from navigation sensors to assist the mariner in route planning and route monitoring, and by displaying additional navigation-related information if required.
system electronic navigational chart (SENC)
System electronic navigational chart (SENC) means a __________________ resulting from the transformation of the ENC by ECDIS for appropriate use, updates to the ENC by appropriate means, and other data added by the mariner. It is this________________ that is actually accessed by ECDIS for the display generation and other navigational functions, and is the equivalent to an up-to-date paper chart. The SENC may also contain information from other sources.
database / database
________________________ means the SENC information that should be shown when a chart is first displayed on ECDIS.
Standard display
_____________________ means the level of SENC information which cannot be removed from the display, consisting of information which is required at all times in all geographical areas and all circumstances. It is not intended to be sufficient for ________________________.
Display base / safe navigation
SENC information available for display during route planning and route monitoring should be subdivided into three categories: ______________________, _______________________, and ________________________.
display base / standard display /all other information
ECDIS should present the standard display at any time by a ______________________.
single operator action
When a chart is first displayed on ECDIS, it should provide the standard display at the ______________ scale available in the SENC for the displayed area.
largest
It should be easy to add or remove information from the ECDIS display. It should not be possible to remove information contained in the ____________________.
display base
It should not be possible to _____________ the contents of the ENC.
alter
_______________ should be stored separately from the ENC.
Updates
ECDIS should provide an indication of whether the information is displayed at a ______________ scale than that contained in the ENC or own ship’s position is covered by an ENC at a ______________scale than that provided by the display.
larger / larger
____________ information or other navigational information may be added to the ECDIS display. However, it should not degrade the SENC information, and should be clearly ___________________ from the SENC information.
Radar / distinguishable
It should always be possible to display the SENC in a _________________ orientation. Other orientations are _________________.
“north-up” / permitted
ECDIS should be capable of displaying information for: _____________ ___________ and supplementary navigation tasks and ____________ ______________.
route planning / route monitoring
The effective size of the chart presentation for route monitoring should be at least _________ mm by ________ mm
270 / 270
The____________ _________ data available in the SENC for the area given should always be used by the ECDIS for all alarms or indications of crossing the ship’s safety contour and of entering a prohibited area.
largest scale
It should be possible to plan an ______________ _____________ in addition to the ________________ ______________.
alternative route / selected route
An _________________ is required if the mariner plans a route across an own ship’s safety contour and across the boundary of a prohibited area or of a geographical area for which special conditions exist.
indication
ECDIS should give an _____________ if the ship, within a specified time set by the mariner, is going to cross the safety contour or is going to cross the boundary of a prohibited area or of a geographical area for which special conditions exist.
alarm
The positioning system and the SENC should be on the same _________________. ECDIS should give an ____________ if this is not the case.
geodetic datum / alarm
During the voyage, it should be possible for the mariner to _______________ the selected sailing route or change to an _________________ ___________.
modify / alternative route
ECDIS should store and be able to reproduce certain minimum elements required to reconstruct the navigation and verify the official database used during the previous _______________
12 hours
