Hello, I'm testing your HUD mods since yesterday and I have noticed a little bug about the altitude.
When I'm on the ground (or close to the sea level) I nerver get to 0 meters with the AGL or the ASL from the HUD (I can get 0 with the default AGL from Arma). It always telling to me that I'm at about 2 or 3 meters higher than I'm.
Hope you can correctly understand my English :)
