Flight-plan point: The number in the interior is the flight-plan
sequence number. When the autopilot is in flight-plan mode,
outer circle is colored in green, if not, blue is used instead.
If the point is the current flight-plan destination, a yellow circle
will enclose the icon.
Destination Point: This point is used to direct the aircraft when not in
flight-plan, take-off or landing modes. In Fixed Wing aircrafts, active
state will also include a representation of the orbit radio the aircraft will
fly once the DP is reached.
Landing Hold center: Only displayed with fixed wing aircrafts, this icon marks
the center of the hold pattern for landing ( See Section 2.10.1.4.5 Landing
mode)

Figure 8: Basic Information Overlay
AGL information is calculated using a Digital Elevation Model (DEM for
short) incorporated into U-See.
Default DEM used in U-See has global coverage but, in exchange, its
accuracy at some points may be lacking. Errors as high as 150 m. can
exist.
Because of this, we advise to take AGL values with a pinch of salt, and
only for broad informational purposes. Never fully trust these values for in-flight
planning. A Safe terrain clearance should be kept at all times.
This warning still applies if high detail DEM is loaded instead of U-See default: DEMs
usually do NOT include obstacles (as buildings and antennas) and terrain may have
changed since the DEM preparation date because of human development.
