Introduction to EFIS module
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.
In order to get into the EFIS module, you will first need to activate the previously installed 3D map of your choice and press the button of the EFIS module, which you can find in the top tool bar. (see screenshot)
It will show an elevation indicator on your right and a groundspeed indicator on your left.
At the top of the screen, it will show the Heading indicator.

At the bottom, there`s a green button that shows a different label depending on how and where you are flying.
You might see the following:
In order to make use of the Artificial Horizon and heading indicator, you must have an iPad/iPhone with internal gyroscopes (iPhone 4/4S/iPad 2 and newer versions).
