With the help of a simulation, I show up to what altitudes the earth appears flat, although it actually has a spherical shape. I prove by means of photos, how the simulation shows the actual conditions, by superimposing the simulation results onto photos.

I derive the formulas to compute the distance between two points for both models. The computations can be carried out using a calculation form. An example is then used to decide which model corresponds to reality.
In this article, this effect can be calculated with a calculation form. The calculation is verified by means of a real flight. In addition, all the formulas used are listed and explained.
