It's simple, he is confusing CURVATURE with sagitta pic related

so that 4000 foot measurement is how much longer the curved ray is than the straight line, covering the same distance, it isn't the HEIGHT of the arc, which is called the sagitta

1093 feet, using http:// www.handymath.com/cgi-bin/arc18.cgi

FE'ers ignore math, it is the only way to believe fe, is to ignore basic math

it's not the curvature that we are discussing as previously shown, the curvature is how much longer the arc is than the ray covering the same distance in a circle. You are looking at the wrong thing
