Proposal 8: The UKADS provider would perform full and final options appraisals of the system end state against the baseline scenarios (applicable to all airspace change proposals)

See Chapter 4, page 42

19. Do you agree or disagree that the UKADS provider should be required to only perform an assessment of the end state design option(s) against the baseline scenarios in the full and final options appraisals – our preferred option?
20. Do you agree or disagree that the UKADS provider should not be required to quantify and/or monetise each of its deployment stages?
21. Do you agree or disagree that year 10 (after implementation with the proposed airspace change) is still an appropriate duration for the appraisal period, given that the deployments within some complex airspace change proposals may span longer or shorter than 10 years?
22. If you disagree, what do you think is an appropriate duration for the appraisal period for a complex airspace change proposal implemented in a series of deployments?
