Great post by the way!!!

2.35 times 40 miles equals 94 times the formula 100 feet equals 9400 feet above your present altitude of FL300, so the tops are FL394.
Wow, that's way too much math for me. I hate math. I look at the radar like this. If I have the range at 20 miles, and I move the tilt up or down 1 degree I'm moving the beam 2,000 feet up or down. At the 40NM range, moving the beam up or down 1 degree is 4,000 feet difference.
Moving it up to 6.0 would be 24,000 feet leaving the tops at 54,000ft. I may be completely balls ass wrong, but I don't think so.
How did I do GravellyPointer?
