**drwls**, Monday, April 4, 2011 at 1:39amAssume the Earth is flat.

Draw a figure with flat horizontal Earth surface along the bottom. Put three points on the figure:

P (airplane)

A (atoll on the ground)

B (point 520 m above the atoll)

Draw the (right) triangle PAB. The angle at P is 8 degrees, aimed below horizontal to point A

It should be obvious that

BA = 520

PB = 520/tan 8 = 3700 m
