The establishment of the Reference Scenario is the first step of the Design Methodology and is undertaken prior to embarking upon the Design Concept. The Reference Scenario usually reflects the current Terminal Airspace, though in some instances, use may be made of a ‘Pseudo’ current Reference Scenario.
As a means of establishing a useful benchmark for comparison with the Design Concept, in order to refine the design objectives and as a mechanism of identifying existing design weaknesses, the Reference Scenario is subjected to qualitative analysis known as a Critical Review.
