A 10 second loop showing the pilot's view of the sky, with a strip along the bottom that shows the pilot's eye and how far away the drone is (schematic, no distances). The drone starts close, large and easy to orient, with its orange nose visible. It then becomes harder to see, depending on the condition selected. Distance: it flies away and shrinks to a dot, so its orientation can no longer be judged. Glare: it moves toward the sun and is washed out. Clutter: it drops in front of a dark tree line and blends in. The drone disappears, the eye in the strip turns red and VISUAL LOST appears. Then the briefed lost-visual action, RECOVER, brings the drone back close where it is clearly visible again. The still frame shows the distance case just before visual contact is lost.
