The EFIS module is a graphic interface which displays real 3D terrain while flying. In order to use it, you will first need to download the 3D data from the Map Store. This is a complex piece of data and it works for both the EFIS module and the Elevation Graph. So this means that once you have installed it in Air Navigation Pro, you won’t need to install the Free Elevation data.
It will show an elevation indicator on your right and a groundspeed indicator on your left.
