Distance to the horizon in Bowditch and other sources
From: UNK
Date: 2024 Jan 16, 12:40 -0800

Can somebody explain why in Bowditch the formula for distance to the horizon is D = 1.169 x sqr root of h

and elsewhere on the internet it is D = 1.22459 x sqr root of h

Where: D is in nautical miles and h is height of eye in feet

Which one should I use?

Thanks

Robert Lafleur
