Notes:


Even with the dramatic improvements in graphics card performance, it is still not feasible to routinely use photographic textures for all kinds of visual flight operations on commodity computer systems.
Near the ground, such as below 1000 ft, the texture would need to show detail that is as small as 10 cm across.
Many jets operate at 40,000 ft with visibilities of hundreds of miles so that 100,000 square km may need to be shown.
This corresponds to 10,000,000,000,000 of the detail pixels which is about 40 terabytes that need to be mipmapped.

There are two grey runways and one white runway. To the right of the white runway is a black taxiway that is often mistaken for a runway – to the surprise of taxiing pilots.
