The display‐dependent effects of both terrain texture density and contrast were assessed using a speed maintenance task in a high‐performance flight simulator. Density and contrast varied in opposite directions with simulated distance, and were found to have opposite effects on perceived speed. The functional range of the interaction between density and contrast was estimated.
