Julian Bray Aviation Expert writes: Has anyone popped over to Paris lately and wondered about the aircraft passing immediately over the traffic tunnel? Or how the Channel tunnel works underwater? The Airport Commission spent three years and £20 million, the result a 400 page document. A document that no one really seems to be happy with... but help is at hand, and from an unlikely set of professionals.
A chance conversation with a delightful and gifted crowd of FIFTY geeks tonight in Peterborough ( Digital People In Peterborough) has unwittingly come up with a solution, that I am told is already technically possible and that is the concept of A STACKED DOUBLE DECKER RUNWAY.

No we've not been on the happy juice, and admittedly fine detail has to be worked on. But this is how it works. The extra runway is contained within the existing airport footprint, and is for the first time made possible by a recent change pioneered by NATS in plotting landing and take off systems, where rigid flight paths are being consigned to history and a spatial funnel approach is being introduced. Knowing how NATS works, it would not be unreasonable to believe that the Airport Commission still knows little or nothing about it. ....
Like an aerial stack, the new elevated third runway at a 45 degree angle to the existing set of parallel runways ( within the pink coloured footprint) would be placed on a solid base for the impact of landing and the remaining runway and runoff provision (verges if you like) possibly on a cantilevered shelf running from bottom left to top right over the existing two parallel runways.
At the end of the elevated section, a gentle turning gradient taxi slope takes the aircraft either down to the original ground zero apron below, simply aircraft would have the advantage of three runways within the overall footprint of two. Simply aircraft would take off and land on two levels and at the same time. So remember where you heard this first, and fifty professional geeks are just waiting to work on it....
