Design
The primary goal of flight procedure design is to provide terrain and obstacle clearance during departure, en route, arrival, approach and missed approach phases; other factors are then considered, notably environmental issues (both particulate and noise pollution) and optimisation of air traffic flow. This is an iterative process that involves a number of related disciplines and requires participation of a wide array of stakeholders.
Validation
Flight procedures are an integral component of the airspace structure used every day by thousands of aircraft at airports around the world. As such, it is of paramount importance to ensure the safety and efficiency of these procedures, so they are subject to a rigorous quality assurance system.
The aim of validation is to obtain a qualitative assessment of procedure design, including its inputs, methods, and outputs in order to ensure the safety, data accuracy, integrity, flyability and fitness for use of the procedure.
Periodic review
All airspace structures, including flight procedures, exist in a dynamic and changing environment. To ensure their continued safety, fitness for purpose and compliance with evolving criteria, procedures are subject to periodic review every few years or whenever justified for operational or other reasons.
