Military airspace over Virginia gets a new vertical split

What happened
The Federal Aviation Administration has vertically divided a restricted military airspace over Pendleton, Virginia. This change allows military aircraft to use different altitudes within the same area, making operations more efficient.
Why it matters
Military training areas are often restricted from civilian air traffic, which can create bottlenecks in busy airspace. By splitting a single restricted area into two vertical zones, the military can conduct different types of missions simultaneously without expanding the overall restricted footprint. This means less disruption for civilian flights and more flexibility for military training.
The signal
Watch for similar vertical subdivisions in other restricted airspaces, especially near major civilian flight paths, as agencies seek to optimize airspace use.
