Top-down schematic of a non-towered aerodrome with an east-west runway, a dashed aerodrome fence and a simple radius circle around it. A drone worksite sits to the east, outside both the fence and the circle. Step 1: 'Outside radius'. Step 2: the runway extended centreline is drawn through the worksite and a light aircraft on a straight-in final approach flies over it; the worksite ring turns red: 'Final approach'. Step 3: a left-hand circuit on the south side and a helicopter route passing near the worksite are drawn and flown: 'Circuit, helicopters'. Step 4: the drone lands early: 'Land or hold clear'. Back and Next step through the scene.
