WebApr 1, 2000 · How Far Away Can You See? If you're a person with normal vision acuity — a rating of 20/20 — and you gaze horizontally from around 5 feet (152.4 centimeters) above the ground, you can see about 3 miles (5 kilometers) into the distance, which is the point at which the Earth's curvature bends away so that the surface is no longer in view. WebGiven that the radius of Earth is 6371km, we can find θ = s r = 1 k m 6371 k m = 1 6371 r a d = 1.56 ∗ 10 − 4 r a d I think h could found by h = 6371 …
WebIn practice, to find , one must be using a value of 8.5·10 3 km for the effective Earth's radius (4/3 of it), instead of the real one. So the equation becomes: = And for the same examples : the radar horizon for the radar at a 1-mile (1.6 km) altitude will be 102-mile (164 km) and the one at 75 feet (23 m) will be 12-mile (19 km). ... http://walter.bislins.ch/bloge/index.asp?page=Advanced+Earth+Curvature+Calculator
