The horizon is about 230 miles away when you are at 35,000 feet above sea level.
I'm not certain that it matters just how tall you are, but at sea level I think the horizon is about 7 miles away.....

You can see the horizon from any altitude on a plane. The horizon is the line where the sky meets the earth or sea, and it appears at eye level regardless of how high up you are.
The distance to the horizon from the shore depends on the height of the observer's eyes above sea level. On average, a person standing at sea level on the shore can see approximately 3 miles to the horizon. If the observer is standing at a higher elevation, such as on a cliff or in a tall building, they can see farther.
the answer is horizon
If you had an unobstructed view, the horizon at sea level would be approximately 24 miles away.

The furthest point an individual can see when looking out to sea is called the horizon. For a 1.8m tall individual, that works out to be approximately 4.8km.
It Maybe B horizon or C horizon
About 2317 x SQRT (50) yards. The 2317 multiplier includes the radius of the Earth and refraction at the sea surface. I interpreted your question to mean, "How far is the horizon when viewed from a height of 50 feet?"
