So what is the business case for a parallel taxiway i.e how would the investment generate extra revenue/profit?
Despite
Onions representations, there is as ever a lot more to it. The safety & time spent back tracking etc. and that ecconomic savings can be achieved are obvious.
Linking this into an a development plan is a trifle more subjective. It ONLY becomes a justifiable business case where the particular expenditure is justifiable in terms of amount of investment available, providing a greater return than other projects currently proposed within the plan. The cost of such a taxiway is likely to be significant and at this time the main beneficiaries appear to be GA related as opposed to Airline having regards to the previous postings on movement categories.
I would suggest that DTV have significantly more pressing projects to take on to make the airport more attractive to both the Airlines and the general public
