For transition into terminal airspace, what is the separation requirement for an A380/AN225?

The separation requirement for an A380 or AN225 when transitioning into terminal airspace is set at 8 miles. This requirement is primarily based on the larger wake turbulence generated by these aircraft due to their size and weight. Large aircraft such as the A380 and AN225 produce significant wake turbulence that can create safety challenges for trailing aircraft. The increase in separation distance to 8 miles helps mitigate the risk of wake encounters, ensuring that following aircraft have sufficient space to avoid disturbances and maintain safe operational distances.

In terminal airspace, where air traffic is often more congested and involves more complex flight operations, this enhanced separation distance is crucial for maintaining overall safety. It allows air traffic controllers to manage the flow of traffic effectively and gives pilots adequate room for maneuvering in response to any potential wake turbulence.
