These pages are used to download charts and data. There are several
pages to select data from.
- Misc - has the Waypoints database checkbox. This
database contains airport, fix, localizer and navaid location
information for the whole country. This database is required
for operation and can not be unloaded. Also contains the
Obstructions and Topography databases used for
obstacle/terrain collision detection.
- Plates - has per-state airport detail information, including
AFD-like data, approach plates,
SIDs, STARs etc. It fills in the information displayed on the
- ENR - IFR enroute charts
- HEL - helicopter charts
- SEC - sectional charts
- TAC - terminal area charts
- Check the charts/databases you want downloaded to your flash drive
then click the Download button at the top. You may click
checkboxes on more than one page before clicking Download.
Needless to say, Internet connectivity is required for this
- You may also click Unload to remove the selected
charts/databases from your flash to free up some space.
- Green text indicates the currently downloaded data is up-to-date and
will remain so at least for several more days.
- Yellow text indicates the currently downloaded data is up-to-date but
will expire in the next few days.
- Red text indicates the currently downloaded data has expired.
NOTE: When downloading plates, it will also read
OpenStreetMap tiles in the
background and it may take longer to load the tiles than the database itself.
These tiles are used for the WairToNow runway diagrams that are useful when
there is no FAA-supplied airport diagram for a particular airport. Internet
connectivity is required for this process to complete, but it is OK if you
disconnect before it completes as it will start back up automatically when
you re-connect to the Internet.
NOTE: There is no download button for Street chart data. The
tiles are downloaded as needed and so requires access to the Internet. You
can preload the tiles by viewing the area ahead of time and WairToNow will
save those tiles to flash for viewing later. Be sure to use various zoom
levels when previewing so those levels will be available when no Internet
access is available. The intent of the Street map is for walking or biking
from an airport to a nearby "$100 hamburger" stand, not for long distances
as needed for driving.
