The elevation shows beneath the symbol. If a line is beneath the eleva-
tion, then the height is AGL, or above ground level. If no line shows be-
neath the height, then it is MSL or above mean sea level.
For example, this obstruction is
315 feet AGL:
This obstructions is 315 feet MSL:
Typically, you'll need to zoom in to a range of 40 miles to see the large
obstruction symbols, and smaller ranges to see the larger obstruction's
height and smaller obstructions. To view smaller obstruction's height, you
may need to zoom in to the 5 mile range.
You can turn the obstructions on or off and
switch from AGL to MSL by highlighting the
"OBSTRUCTIONS" label on the "Air Map
Options" menu, then pressing the right arrow
key. The obstruction menu appears as shown
at right. The AirMap defaults are: obstructions
from 205 to 499 feet (shown as 200-500 on
the menu) off and obstructions 500 feet and
above on. AGL defaults on, also. You can
change any of these by highlighting the de-
sired menu, then pressing the left or right arrow keys.
