ABOVE: Current Class D airspace will be recategorized as Class G from February – albeit with some restrictions

The Civil Aviation Authority has approved changes to the airspace currently known as the Manchester Low-Level Route (MLLR), with the new and extended North West Transit Corridor to be reclassified as Class G airspace from February 2025.

Nestled between the Liverpool CTR and the Manchester CTR, the MLLR allows general aviation pilots to navigate between both airports by providing a crucial north-south routing option. However, “by simplifying the structure of this critical corridor and reducing the risk of mid-air collisions, we’re ensuring that pilots can continue to benefit from efficient transit… without compromising on safety,” commented Jon Round, Head of Airspace, Air Traffic Management and Aerodromes at the CAA.

Under the amendment (prompted by the expiration of the current exemption in this airspace), the new Glass G uncontrolled airspace will be 0.65 nautical miles wider to the east than the boundary of the existing MLLR. A new maximum altitude of 1,500ft will also be 200ft higher than existing restrictions allow. However, the reclassified airspace will also include a Restricted Area limiting the speed and weight of permitted aircraft, alongside visibility and QNH setting restrictions.

“This amendment is part of our ongoing commitment to modernising the UK’s airspace and improving air traffic management for everyone,” concluded Round.
