Obstacle Data Viewing Range
The Obstacle Data Viewing Range option selects whether the Obstacle Data
is shown on the Navigation Map. Obstacles will be shown at and below the
selected map range. Map ranges above this value will not show the Obstacle
Data. In the range selection example below where 30 NM is selected, obstacles
will be shown at map ranges of 30 NM and lower.

Figure 3-20 TERRAIN Altitude/Color Correlation
Grouped obstacles are shown with an asterisk (as shown in the Windmill in
Group example above). The color of the asterisks is tied to the relative altitude
of the highest obstacle in the group, not other obstacles within that group.
Obstacles are grouped when they would otherwise overlap. If map zoom scale
is change sufficiently that obstacles can be drawn without overlapping they will
be depicted individually.
Obstacle databases created for software version 7.00 or later may include
HOT lines depending on the type of obstacle database installed. Hazardous
Obstacle Transmission (HOT) Lines are those power lines that that have been
identified as a potential hazard to aircraft. The installed obstacle database type
