Altitude above ground / AGL in Flight Data Display

Hello Everybody,

is it possible to show the altitude AGL in the flight data menu? There are some options to choose but it is not clear what they do:

Thanks and best regards

Hello @Rider_on_the_storm

From AGL you say receiving some kind of rangefinder data measuring the altitude above ground level? If this is the case you can use Sonar Range.

“Alt” is altitude referenced from the home position which I suppose is what you want.

Thanks for your replies.
What I need is the altitude above ground at the current position, not the home position → GPS-altitude minus SRTM altitude
