2. OPERATIONAL OVERVIEW
2.1 ECDIS Display
The ECDIS (Electronic Chart Display and Information Systems) screen is divided into
several areas, as illustrated below. (The layout may be slightly different depending on
your monitor’s resolution.) The ECDIS operational area has no limitations. That is,
high latitudes (85° and higher) are correctly displayed always. The ECDIS uses “cy-
lindrical equidistant” projection for areas of high latitude and small chart scales. All oth-
er conditions use the “orthographic” presentation.
Note: If the display indications freeze (because of ECDIS error, etc.), the buzzer
sounds continuously. Restart the system to restore normal operation.
• The Status bar provides for selection of display mode, chart format, etc.
• The Sensor information box displays ship's speed, course and position and selects sensors.
• The Own ship functions box applies offset to the chart; changes geodetic data system, and pro-
vides true motion reset.
• The Route information box shows route and waypoint data, when a route is selected for naviga-
tion.
• The Overlay/NAV Tools box provides for setup of the radar overlay and navigation-related func-
tions.
• The Alert box shows operational and system alert messages.
• The VRM boxes measure the range to an object.
• The Permanent warning box displays chart-related warning messages.
• The EBL boxes measure the bearing to an object.

™
provides quick access to functions such as brilliance adjustment, display
palette and the menu. The contents change according to the ECDIS mode selected.
• The Chart scale/presentation mode box selects the chart scale and presentation mode.
• The Cursor position box shows the latitude and longitude position of the cursor and the TTG to
the cursor.
