This chapter provides an overview of the Design Methodology which consists of the Reference Scenario, the Design Concept and Design Guidelines. It also explains the context of the Design Methodology in a Terminal Airspace design project, its potential applications and basic assumptions underlying the design process.
1.1.1 REFERENCE SCENARIO (CHAPTER 2)
The Reference Scenario and a Critical Review of this reference marks the starting point of the design methodology. Whilst its relevance might not be apparent, its importance is three-fold:
.
it is an efficient way of refining the design objectives given that a design project is usually undertaken as a means of improving upon the existing design; and
.
it provides a benchmark against which the design concept can be compared; and
.
it prevents design ‘weaknesses’ identified in the Reference Scenario in the Design Concept, being repeated.
For the above reasons, the Reference Scenario is where the Design Methodology commences.
1.1.2 DESIGN CONCEPT (CHAPTERS 3 & 4)
The Design Concept marks the second major step of the Design Methodology but the starting point of the design process.
The Design Concept is not limited to designing routes, holds, the airspace and sectorisation but also includes all the preparatory work involved in the design process. For this reason, the Design Concept is made up of several components, which are usually undertaken in the (left-to-right) order illustrated below.

Several remarks may be made about the above illustration:
.
The reverse arrows and expression Qualitative Analysis:. These serve to show that when the design stage is reached, a continuous cross-checking process is required to ensure that safety and performance criteria are being met and that the assumptions, constraints and enablers are consistent with the design.
