6. CHART OVERVIEW
6.1 Chart Screen Overview
The chart screen is divided into several areas, as illustrated below (The layout on your
screen may differ slightly depending on your monitor’s resolution).The chart screen
operational area has no limitations. That is, high latitudes (85° and higher) are correct-
ly displayed always*. The chart screen uses “cylindrical equidistant” projection for ar-
eas of high latitude and small chart scales. All other conditions use the “orthographic”
presentation.
*: High altitudes are not supported in RADAR mode.
