Post Implementation Review of the North West Transit Corridor

Overview

In February 2025 the UK Civil Aviation Authority introduced the North West Transit Corridor, replacing the Manchester Low Level Route.

The change was introduced to improve safety, simplify the airspace structure, reduce airspace infringements and maintain access for General Aviation operating between the Manchester and Liverpool control zones.

As part of the regulatory process for reviewing airspace changes, the CAA is now undertaking a Post Implementation Review (PIR). This review considers whether the change has delivered the intended outcomes and whether any unintended impacts have occurred.

Feedback from pilots and other airspace users forms an important part of this review.

About the survey

This short survey asks about your experience of operating in the North West Transit Corridor since its introduction.

The survey should take around five minutes to complete.

Your feedback will help inform the CAA’s assessment of the effectiveness of the change.

Who should respond

We are particularly interested in hearing from:

• General Aviation pilots
• Aircraft operators who operate in the North West of England
• Flying clubs and training organisations
• Other stakeholders familiar with the corridor

How your feedback will be used

Responses will be analysed by the CAA and used to support the Post Implementation Review report for the North West Transit Corridor.
