it does start to clear the way to extend 06L, allowing a better separation from 06R!
Does it ? It won't allow for any greater lateral distance between the two runways.
If 06L/24R were extended across Ringway Road towards Heald Green then it would give a greater TORA / LDA on that runway, (which is already plenty long enough),but this dosen't really do anything seperation wise AFAICS
