What is the separation for a Cat I aircraft landing behind a Cat III?

The key idea is wake turbulence separation when an aircraft landing under Cat I follows an aircraft using Cat III approaches. Cat III operations involve larger, heavier aircraft that can generate stronger wake vortices. To ensure the trailing Cat I has enough time and space to avoid these vortices during the final approach and landing, a larger separation is required—6,000 feet. The smaller figures wouldn’t provide adequate margin against the stronger wake from the Cat III aircraft, which is why 6,000 feet is the best choice.
