Please note that the reported pressure is the actual ambient pres-
sure (not altimeter setting) at the aircraft’s current altitude. Wind
speed and direction are displayed graphically using a barb and flag
system (see figure on page 105) connected to a “pole” that points
in the direction FROM which the wind is blowing relative to True
North. In the following example, the aircraft is at 3500 feet, wind
is from the southeast at 15 knots, OAT is 47° Fahrenheit, ambient
pressure is 26.34 inches, and visibility is 25 statute miles. Note that
unlike the station model used on Surface Analysis charts, no sky
cover information is provided.
To turn ON/OFF aircraft spot weather simply click the FACILITY
“show” button at the bottom of the MAP Page. On the “Show Fa-
cilities” dialog box click on the Aircraft Info “SHOW” button. This
button is an ON/OFF toggle that will turn yellow when pushed in
(ON). The spot weather data appears at the upper-left corner of the
MAP Page at the top of the shaded information display region.
NAVIGATION DATABASES
All airports, airport lighting, fixes, NDBs, VORs, localizers, glide
slopes, communications data etc. are contained in regional naviga-
tion data bases. This data must be loaded for use in the program.
To understand the structure of the NAV databases, press
the ZOOM out ( - ) button several times until an entire continent is
visible. Using North America (shown below).
For example, notice there are boxes visible across the U.S. that de-
fine the regional boundaries of each NAV database. From this same
view you can also determine if a specific NAV data base (region)
is loaded. Gray boxes indicate data is available but not loaded. Red
boxes indicate the data within its boundary is loaded and ready for
use.
Note: Each NAV data base (region) is labeled for identification.
The label (USNW) shown below is for the United States North
West.
