If anyone cared to read the 'Funding and Financing' report on the Davies website they would see that a 50% increase in HAL's airport charges would be required to generate a commercial return on the investment in R3, including the £6bn estimated by Davies for surface access costs.
Few observers have questioned whether this 50% increase is achievable, and the stratospheric slot values lend support to the view that HAL could materially increase its airport charges without affecting demand.
Shed is clearly right to say that there is a level of R3 costs that would make the project unviable. But I don't think we are there yet. Although if TFL have their way they would kill the project, which is clearly their (political) aim, driven by Boris.
(Ps. I am inclined to agree with others that this is getting way off-topic)
