The elevation angle has to be modified to take into account the bending effect.

The nominal elevation angle for this case is -0.5 degree.

In this case, a simple idea is to try some low elevation angle and let the ray reach the desired altitude.

This meant that the range, not elevation angle was set on the sight.

The distribution of power versus elevation angle is known as the vertical pattern.

However, various arrangements were used to achieve the required elevation angle.

This led to many calculations relating elevation angle to range.

This meant that different guns needed a different elevation angle for the same range.

The elevation angle is also measured at 3D radars as a third coordinate.

There are a large number of reflectors on the ground at these elevation angles.
