It’s also baked into tar1090[1] which is a little more maintained of a package and pretty easy to get set up if you’ve got an SDR and 1090MHz antenna to track planes.
It’s a fun little hobby - where I live there really isn’t much of a reason to do it as there are enough other 1090MHz receivers in the area, but it still is cool when I look and see obscure jets flying overhead.

This is also going to be interesting for figuring out the minimum altitude for maintaining the link to an RC airplane for a given distance.

We actually added this as a feature to our sharing software at Plane Finder using our own modelling.
If you sign up and then view your stats on the web you can compare your actual to the predicted.

In fact, the adsb-receiver[1] software package for setting up an aircraft tracking station includes a neat feature where you can use HeyWhatsThat to calculate maximum line of sight distances to aircraft at various altitudes and include these contours on your aircraft tracking map.
* atmospheric phenomena such as density or humidity differences or reflections from other aircraft, the moon, or even meteors can enable reception over the horizon.
