- Inside Control Zone: This is a cylindrical area extending from the surface up to 3000 feet altitude. Within this zone:
- Aircraft must maintain a horizontal distance of at least 2 km from clouds.
- Vertical distance from clouds must be at least 500 feet.
- Visibility must be at least 5 km.
- Above 3000 feet altitude (but below 10,000 feet amsl):
- Aircraft must maintain a horizontal distance of 5 km from clouds.
- Visibility must be at least 5 km.
- The area must be clear of clouds and in sight of the surface.
- At and above 10,000 feet amsl:
- Aircraft must maintain a horizontal distance of 8 km from clouds.
- Visibility must be at least 8 km.
- Terrain Consideration: The diagram includes a hill with a height of 1000 feet above ground level (agl), indicating that visibility and cloud clearance rules apply relative to the terrain.
- Visibility Icon: The eye symbol with a distance (e.g., 5 km or 8 km) represents the minimum visibility required at different altitudes.
