A 10 second loop in side view, not to scale. A remote pilot launches a drone over rising ground on a sunny day. Three limits are drawn one at a time: a VLOS sight line from the pilot's eyes to the drone, a 120 metre (400 feet) AGL ceiling that follows the ground surface rather than the launch point, and a 30 metre dome around a bystander. With 'Inside limits' selected, the drone flies the job inside all three and lands. With 'Too high' selected, the drone climbs beside a tall mast and breaks through the ceiling, which turns red, and APPROVAL OR NO-GO appears before the drone descends. With 'Too close' selected, the drone flies into the bystander's 30 metre dome, which turns red, with the same message. The still frame shows the drone working inside all three limits.
