Post Implementation Review of the North West Transit Corridor

The UK Civil Aviation Authority is undertaking a Post Implementation Review of the North West Transit Corridor, which replaced the Manchester Low Level Route in February 2025. 

The review will assess whether the change has delivered its intended objectives, including improving safety, simplifying the airspace structure and maintaining access for General Aviation. 

Pilots and other airspace users who operate in the area are invited to share their experience of the corridor through a short online survey. 

The survey will close on 8 June 2026.
