Enter in the Format of Lat 00 00.000 N and Long 000 00.000 W
Visible Range from an Elevation above Sea Level
Enter your elevation (Eye Height) above sea level (in metres) to estimate how far you can see to the horizon.
This is for general interest only and not for navigation or operational use.
Formula (nautical miles): distance_nm = 2.08 × √height_m
Add 8% for typical refraction if checked.
Includes optional 8% refraction correction. Real visibility depends on air clarity, light, and curvature anomalies.
