Ghostrider Posted March 25, 2009 Report Share Posted March 25, 2009 ^^ Or then got it off aircraft navigation charts, I would think most of them give at least +20m altitudes just to make sure the tree hopping type pilots do actually miss obstacles....and even still, its not always enough.

Pooks Posted March 26, 2009 Report Share Posted March 26, 2009 I suppose it would depend whether you measure it from the ground you are standing on or where the red light is on the highest obstacle. Quote Link to comment Share on other sites More sharing options...
