4.1.8 GPS DATA INVALID
If you lack a GPS connection, there will be a red cross across the screen and ’GPS DATA
INVALID’ written in a notification box.
If this happens, check that your device has a clear line of sight from the GPS antenna to the
sky, and wait for the device to connect.

NOTE
In order to use navigation pages to their full extent, be sure to have airspace (.cub),
turnpoint (.cup) and airport (.af) files installed. Some of these, like .cup and .cub
files, are available on competitions, from club managers, or governing national air
bodies (like DAeC), while other, like the .af file, are provided solely by LX navigation.
NOTE
Files provided by LX navigation (.cub and .af) can be found on
http://www.lxnavigation.com/support/database/. LX navigation does not provide
official .cup files, for unofficial turnpoint files, you can check with your club mates
and webpages like https://www.openflightmaps.org/
.
NOTE
All final glide calculations take into account the current wind speed and direction,
as well as reserve altitude and selected MC value. On the Task navigation page,
the final glide calculation takes into account your kinetic energy as well, as
explained in the said page.
