The Elevation Profile (ICAO):
Use the editable elevation profile to compare your planned flight altitudes
with the highest elevations in the vicinity of your flight route.
As long as your route goes above the black framed rectangles,
you don't have to worry about the obstacle clearance.
However, the sections of your route, which lie within the black framed rectangles,
should attract your attention. Here your planned altitude may be unsafe! On the
map views (41 KB) that parts of your route will be displayed in red colour.
