I add a digital radar altimeter to the top line of sight of the cockpit s I use most
Usually Light twins
My eyes are old and tired and I have found the views in FS over the years unrealistic in comparison to real life (but still fun)
The digital Altimeter stays on at all times giving me an idea of what is happening below me at all times
Above 500' the numbers are green, below yellow and, red as you get close to the ground
It helps me
Regards Chris
