The horizon dip measurement is the angle between the horizontal (the line perpendicular to the vertical at a specific point) and the apparent horizon.
On a globe, you would expect this angle to increase with increasing altitude, because the horizon would drop away with the curve.
On a flat earth, if the plane is infinite, you would expect no drop of the horizon with increasing altitude. You would just be able to better resolve distant points because of the greater angular resolution between them.
Measurements will be forthcoming.

Horizon Dip Calculator The following calculator estimates the dip of the horizon based on altitude above Earth's surface.
Formula
\[ \text{Dip} = \sqrt{\frac{2h}{R}} \]
Inputs
- Altitude (h): Height above Earth's surface in meters.
- Earth's radius (R): Approximate value is 6,371,000 meters.
Result
\[ \text{Result} = 0 \]
