Bridge Team Management - Chapter 8 - Navigating with integrated bridge and electronic chart systems Flashcards
It is recommended that system checks are carried out at the ___________________ of each watch and at regular intervals during the watch to ensure that the OOW is satisfied with the system in use is functioning correctly and that all connected sensors are providing valid data.
beggining
Even with a fully type approved ECDIS, the approval is only valid in the sea areas for which the offcial _________________________ has been installed in the system and corrected to include the latest updates.
S57 chart data (ENC)
The RCDS (Raster chart display systems) mode does not have the full functionality of ECDIS and can only be used together witn an apporpriate portfolio of up-to-date __________________.
paper charts
Nautical chart or nautical publication is issued officially by on or the authority of a government authorized Hydrographic Office or other relevant government institution. The ___________________, on the other hand, are available from a number of sources, including government authorised hydrographic offices and commercial suppliers, in two formats, ___________ and _____________.
electronic chart / raster / vector
In its own way, the ECIDS is a mini voyage data recorder. It must be able to record and reconstruct the vessel’s navigation history, along with verifying the official database used, for a minimum of ______ hours.
12
The possible options for ECDIS back-up are: a second, fully independent, type approved ECDIS, an ECDIS operating in the __________ mode and a full _______________________ corrected to the latest Notices to Mariners covering and showing the intended voyage plan.
RCDS (raster) / folio of paper charts
A _____________ chart is a facsimile image of an existing paper chart. This type of chart has no ______________ of information, so the user has no control over the look and contentes of the displayed chart image, other to change to daylight no night palettes.
raster / layering
The raster charts allow for automatic _________________ of chart content.
update
__________ is an IMO approved vector chart, produced in the ________ format, that is approved for use with ECDIS.
ENC / S-57
Vector charts support a _______________ of information which allows the user to display only the chart information that is desired for the current operating enviromment.
layering
_______________ will allow ECDIS to safety check the ship’s route to warn the operator about certain hazards.
Vector charts
A ___________________ is a Mercator grid over a black background. Is the default display when no chart is loaded or available.
planning sheet
Degraded system accuracy is most often associated with one or more of the following: ________________ , shifting of buoys, inaccurate hydrographic data, __________________ , poor resolution, ________________________, incorrect system configuration or calibration and __________________________ .
chart datum / sensor limitations / user set-up errors / system or sensor malfunction
Errors of ___________________ are not the same as degraded system accuracy, but can have a similar undesirable impact on safe navigation.
interpretation
Berth to berth passage plans are recommended but it may be appropriate to make a number of ___________________ for the pilotage elements, taking into account alternative routes through a pilotage district, for example.
separate plans
One of the benefits of ECS is that the system will automatically check for _______________ along a ship’s current course or voyage plan, provided that the appropriate parameters have been set in the first place.
danger
Electronic systems are only as good as ________________________________.
