FAST Generic Presentation March, 2007. 17 FAST IMPORTANCE OF IDENTIFYING AREAS OF CHANGE… The future is not necessarily a direct extrapolation of the past. Present and near-term safety interventions that are intended to prevent future accidents caused by previously known hazards may not be enough to prevent new types of accidents from happening in the future. A mid-1990’s study by a major manufacturer looked at accidents in which airplane systems were involved in an accident or where they could have prevented the event and did not. It was found that in approximately 70% of the accidents involving airplane systems, the original design assumptions were inadequate for the situation existing at the time of the accident due to changes in… - the aviation system - airplane operational usage - personnel demographics - evolving infrastructure or other considerations.
FAST Generic Presentation March, 2007. 18 FAST CHANGING NATURE OF ACCIDENTS “Technological innovations are changing both aircraft and the airspace in which they operate. Cumulatively, these technological changes aim to increase reliability throughout the aviation system and vastly improve safety in the skies. These changes include systems designed to move aircraft more efficiently in the air and on the ground, methods for providing pilots and ground controllers with better information about traffic and weather conditions, and improvements in aircraft components and design. “The growth in aircraft system complexity is exponential in many areas, with the most significant trend being the inter- connectedness of systems. Current-generation aircraft operate as highly integrated systems with extensive cross-linking. As system complexity grows, so does the concern about hidden design flaws or possible equipment defects. “Accidents involving complex systems and events present investigators with new and different failure modes that multiply the number of potential scenarios they must consider. The historically common causes of accidents are occurring less frequently, leaving more challenging accidents to diagnose.” * * - Safety in the Skies Personnel and Parties in NTSB Aviation Accident Investigations-Master Volume, Chapter Three: Emerging Aviation Trends: Potential Impact on Aircraft Accident Investigations, By: Liam P. Sarsfield, William Stanley, Cynthia C. Lebow, Emile Ettedgui, Garth Henning, published in 2000
FAST Generic Presentation March, 2007. 19 FAST Areas of Change: Some Principles Changes must be understood as broadly as possible. To bring consistency and coherence to the process, Areas of Change are grouped by categories. The diagram on the next sheet illustrates the eleven broad categories of Areas of Change affecting aviation identified by the FAST

Submissions should be made to Rudi den Hertog, Chief Engineer, Fokker Services, FAST Co-chair, email@example.com
FAST Generic Presentation March, 2007. 21 FAST What is an Area of Change The Global Aviation System (GAS) is in fact a "system of systems." Examples of "systems" include –airplanes, –air traffic control systems, –company processes, and –regulatory systems. The future GAS will be fundamentally different than what exists today because changes affecting the GAS will continuously occur as the system evolves into the future. The ongoing process of change including both evolutionary and sudden, disruptive events or paradigm shifts must be considered for effective safety risk management.

FAST Generic Presentation March, 2007. 23 FAST Importance It is important that aviation practitioners who are designing future systems have foreknowledge of potential future hazards. A change to any one system could affect other systems. Interactions of future changes to several systems could likewise affect the whole. These changes could have adverse impacts on the safety of the Global Aviation System. The goal of "discovering" future hazards is to eliminate, avoid or mitigate hazards in the future that may arise as a result of the changes. This will reduce the risk of future incidents and accidents.
FAST Generic Presentation March, 2007. 24 FAST WHAT’S FAST? OBJECTIVES WHAT’S SO SPECIAL? WHAT FAST IS AND WHAT NOT COMPOSITION CORE TEAM
FAST Generic Presentation March, 2007. 25 FAST OBJECTIVES of the FAST method Studying potential future changes in the Aerospace System in order to : Identify relevant Areas of Change [AoC] either within or external to the aviation system Identify Hazards, both inherent to the AoC as well as those arising from interaction with other AoC’s Develop recommendations to eliminate hazards or mitigate their effects, such as: Tools to analyze and mitigate the hazards including studies and simulations to quantify the risks of identified hazards Providing probable hazard information to influence entities that shape the future
FAST Generic Presentation March, 2007. 26 FAST DISTINCTIVE CHARACTERISTICS Concept of considering a comprehensive set of “Areas of Change” affecting aviation safety Using a broad representation of domain experts representing diverse affected organizations within an Expert Team hazard- discovery setting looking for direct and indirect hazards Direct- as well as Indirect hazard(s) identification, with indirect hazards resulting from interaction among AoC’s within a novel future operational scenario - identifies hazard catalysts not ammenable to computational modeling Maintaining and providing to the aviation community an up-to- date repository of AoC’s, possible aviation futures, Technology Watch Items & hazards. Offering a Future Hazard Analysis method that can be used universally by any organization Having a FAST Core Team ready to assist Customers using its Future Hazard Analysis method
FAST Generic Presentation March, 2007. 27 FAST What the FAST is and is not… The FAST process is a systematic approach to identification of: –Wide range of changes affecting aviation safety (AoC’s) –Systemic vulnerabilities and hazards within highly integrated systems –Boundary aspects not only within aviation but external to it that may be the catalysts for future hazards including common cause factors and interactions The FAST process is not a risk assessment method - that is, it doesn’t estimate relative frequency of hazards. The FAST generally does not recommend or develop safety interventions - FAST can feed Risk Assessment and Risk Management processes in which safety interventions are developed and implemented, and action efficacy is monitored. These are best left to the customers.

FAST Generic Presentation March, 2007. 29 FAST FAST METHOD DEFINITIONS –CUSTOMERS –STAKEHOLDERS –EXPERT TEAMS –TECHNOLOGY WATCH ITEMS PROCESS FLOWS
FAST Generic Presentation March, 2007. 30 FAST DEFINITIONS: CUSTOMERS are organizations that have authority to either recommend or implement changes to the Global Aviation System STAKEHOLDERS are organizations that may be impacted by an envisioned change to the Global Aviation System EXPERT TEAM Drawn from Customer & Stakeholder organizations Selected by FAST and Customer collaboratively based on the envisioned future being considered Must have specific expertise associated with the future being evaluated No experience with FAST method required initiate changes affected by changes
FAST Generic Presentation March, 2007. 31 FAST DEFINITIONS, cont. TECHNOLOGY WATCH ITEMS A repository of tell-tale advances in technology and other relevant factors that may indicate which possible aviation future is unfolding and thereby signal if postulated direct hazards and/or indirect hazards (interaction hazards) are coming about. To be revisited after significant events (incidents & accidents) and be part of risk assessment plans. Maintained for the benefit of the worldwide aviation community similar to the CAST Problem Statements.

FAST Generic Presentation March, 2007. 51 FAST If at some point in the past, a study of the potential future hazards related to Reduced Vertical Separation Minima (RVSM) had been conducted, the Expert Team performing the analysis would likely have needed to generate the following description of the potential consequences of implementation of RVSM in order to extract potential future hazards… "Assuming that each airplane has physical enhancements and each crew has procedures to properly manage vertical separation less than current rules, we believe that increased collision hazard is not likely. There however is a slight hazard increase due to wake turbulence descending from overhead airplanes and causing loss of control of encountering aircraft. We therefore recommend that there a study be done of all existing airplanes to determine the likelihood of a strong cruise wake descending to flight levels occupied by other aircraft, minus the altitude uncertainty. Altitude uncertainty must be considered and quantified in the study however, because actual separation may be much less than the candidate reduced value. We also recommend review of TCAS/ACAS protection with the FAA to ensure that the TCAS will not significantly contribute to collision likelihood. We want to avoid TCAS causing an accident. We hear however that the Military will be fielding new navigation technology, GPS, which if applied to civilian airplanes, will significantly increase the lateral precision with which airplanes will fly intended airways. Airplanes will then be closer to each other vertically and laterally. In this case, collision and/or wake vortex upset risk may significantly increase. If you see intentions to adopt GPS technology for civil transport navigation (watch item), then we recommend that studies are conducted and the Industry agrees to mitigating practices such as intentional cross-track stagger. Care should be taken when doing so to ensure that wind direction is considered in the study."
