How must aircraft be routed around restricted areas like R931A and R931B?

Routing aircraft around restricted areas like R931A and R931B is essential for maintaining safety and compliance with airspace regulations. These restricted areas are designated for specific uses, such as military operations or hazard zones, where civilian aircraft may not safely navigate due to potential dangers.

Routing around the northern side of these restricted areas ensures that aircraft maintain a safe distance from any activities occurring within the restricted airspace. It helps avoid any inadvertent entry into zones where operations might jeopardize safety, effectively protecting both the aircraft and those involved in the activities within the restricted areas. This practice aligns with standard operating procedures that prioritize safety and adherence to regulatory requirements.

In contrast, routing directly through restricted areas would pose significant risks and is strictly prohibited. Options suggesting routing over or around the southern side are either less common or may conflict with the safest and most efficient path based on the specific layout of the airspace. Proper routing is crucial for flight safety, which is why directing traffic around the northern side provides a clear and safe standard.
