    SUMMARY: David Hinson, Administrator of the Federal Aviation 
    Administration (FAA), stresses that Zero Accidents is the only 
    acceptable safety goal for the aviation industry and the FAA. This 
    notice offers some ideas for the elements needed to establish an early 
    warning capability for existing and emerging safety concerns that would 
    move the aviation industry towards Zero Accidents, and challenges the 
    aviation industry to participate in developing that capability. Because 
    of an emerging combination of improved cooperation between airline 
    management, labor, and various governments, advancements in information 
    technologies, and the political environment in several countries, the 
    international aviation industry has an unprecedented opportunity, by 
    sharing and analyzing aviation safety information, to reach Zero 
    Accidents.
        This notice (a) solicits comments on the Global Analysis and 
    Information Network (GAIN) concept and implementation strategy for 
    collecting and analyzing aviation safety data, and (b) invites 
    participation in the development of proof-of-concept prototypes. All 
    interested parties, whether or not in the aviation community, are 
    invited to comment on the ideas presented, offer alternative solutions, 
    indicate interest in helping to develop a GAIN prototype or the overall 
    system itself, and comment about how government aviation safety 
    agencies can best help the industry reach Zero Accidents.
    
    DATES: Comments in response to this call for action must be received by 
    June 14, 1996.

    202-267-GAIN (202-267-4246).
    
    SUPPLEMENTARY INFORMATION: The aviation industry has made remarkable 
    progress in reducing aviation accident rates. With today's volume of 
    flights, the industry would have suffered more than 10,000 fatalities 
    last year worldwide if the accident rate had not improved so 
    dramatically since 1960. Because of this major decline in the accident 
    rate, the industry now suffers an average of less than 800 fatalities 
    worldwide per year. However, the rate has remained stubbornly 
    consistent for about the last 10 years; and at today's accident rate, 
    forecast growth in air transportation demand will lead to more than 
    4,500 fatalities worldwide per year by 2025--clearly an unacceptable 
    result.
        Sound methods for certifying the safety of new aviation products 
    and procedures, as well as surveillance activities that help to ensure 
    safe operation and maintenance of these products and procedures, have 
    contributed significantly to the current safety levels of the aviation 
    industry. Within the framework of these regulatory methods, 
    technological advances in engine performance and reliability, airframes 
    and materials, air traffic control, cockpit automation, and simulator 
    training have contributed to the safety of the aviation system. 
    Compliance inspections, accident and incident investigations, special 
    studies, and program evaluations are the fundamental methods of 
    continuing surveillance in the operating environment, and safety has 
    improved significantly over the years in part because of the lessons 
    learned by using these methods to understand the mistakes and 
    oversights of the past.
        Yet all too often, the industry has not been able to use data about 
    accidents, incidents and other system anomalies to become aware of 
    existing or emerging safety problems in time to take preventive 
    measures. Just as traditional product design and manufacturing methods 
    eventually gave way to new, improved principles and methods, a new 
    safety information paradigm, with much greater sensitivity to anomalies 
    in daily aviation system operations, could help the industry reach Zero 
    Accidents. Just as aviation product improvements
    
    [[Page 21523]]
    
    of the past have been fostered by technological advances, improvements 
    in aviation safety monitoring and alerting will become possible as a 
    result of major advances in information management technology.
    
    An Outline of a New Safety Monitoring Paradigm
    
        The industry must develop a significantly improved operational 
    early warning capability that is sensitive enough to detect and alert 
    the aviation community to existing and emerging problems. A major 
    aspect of this capability is the sharing of safety information, both 
    within categories in the industry, e.g., carriers must share with other 
    carriers and manufacturers with other manufacturers; and across 
    categories, e.g., labor, management, carriers, manufacturers, air 
    traffic controllers, airport operators, and others must share with each 
    other. Creating useful information, however, generally requires the 
    collection of large amounts of data, and it also involves the careful 
    analysis of that data. Rarely would there be any need or desire to 
    share any raw data, but the sharing of the analysis of the data--the 
    information--could be mutually beneficial. Gathering and analyzing 
    large amounts of qualitative and quantitative aviation safety data to 
    better understand routine system operations is the foundation of the 
    Global Analysis and Information Network (GAIN) concept.
        The GAIN system would be more sensitive to conditions that signal 
    increased safety risks because it would contain information about 
    normal aviation system operations. The statistical baseline for normal 
    aviation operations, constructed with digital flight and ATC radar 
    data, among other major and currently untapped sources, would be the 
    plumb line from which deviations are measured. The importance of 
    obtaining information about a far greater percentage of aircraft 
    operations has been illustrated repeatedly by all-too-typical accident 
    investigation findings of earlier flights that experienced problems 
    similar to the accident aircraft. A truly effective early warning 
    capability would involve significant improvements in information 
    feedback and analysis for aviation operations. At a minimum, the GAIN 
    concept would add the following new elements to the existing monitoring 
    systems to improve sensitivity:
    
    --New data sources that would improve risk assessment and provide a 
    baseline for normal flight operations, thus improving the chances of 
    early anomaly detection.
    --New and innovative data management and analytical techniques and 
    methodologies that quickly reveal obscure and/or infrequent data 
    patterns and associations.
    --New methods to disseminate the findings quickly and globally to all 
    who could use them to improve aviation safety.
    
    Analytical Strategies and Automated Tools
    
        The proposed analysis process would be based upon new sources of 
    information and new information technology capabilities. First, 
    information from voluntary reporting programs (such as the confidential 
    Aviation Safety Reporting System (ASRS), or the Air Safety Reports 
    (ASR) used by certain airlines) and mandatory incident reporting 
    systems (such as the Pilot Deviation or Runway Incursion data bases) 
    would be subjected to a range of analysis tools. These include advanced 
    data pattern searches--which can be performed autonomously on the data 
    by ``intelligent agent'' automation tools to discover patterns or 
    associations, finding the ``needle in the haystack.'' ``Intelligent 
    agent'' software would aid analysts in discovering thematic 
    associations in text data bases, and data visualization tools would 
    show the analyst associations in data base elements. Application of 
    such data mining analysis tools would provide a more focused 
    understanding of operational safety concerns much sooner than current 
    analysis techniques. The data management and analysis take place in a 
    ``data warehouse'' where operational data are extracted from existing 
    systems and, through a series of steps that standardize and improve the 
    quality of the data, the data are transformed into a data base designed 
    for targeted analysis. Within a ``data warehouse'' environment, safety 
    analysts can employ various data mining strategies.
        Once existing or emerging safety concerns are identified, 
    hypotheses that are developed to explain them can be tested using 
    empirical digital flight data, ATC radar data, or other appropriate 
    data sources. A focus on remedial measures would at times result from 
    an analysis of digital flight data or ATC automated data, both vast 
    sources of empirical data.
        As a result of new information technologies, we have the 
    capability, for the first time, to monitor and analyze the parameters 
    of safe and normal flight. Until very recently, it has been very 
    difficult to obtain accurate and reliable information on normal flight 
    operations. Now, thanks to new computer technologies, we can use flight 
    data recorder and radar information to generate large amounts of very 
    accurate and detailed information about flight performance. For 
    example, the Boeing 777 records information on 700 flight parameters 8 
    times a second. Several countries, mostly in Europe, have programs in 
    which a carrier or civil aviation agency routinely monitors and 
    analyzes operational data captured on flight data recorders.
        Statistical analysis of digital data or ATC automated data from 
    normal flights would yield a baseline of routine operations that can be 
    used to detect variations from norms. In addition, baseline statistics 
    would help safety analysts quantify operating risks within, as well as 
    beyond, the envelope of normal operations. By collecting and analyzing 
    information primarily about what went wrong, we are missing the 
    opportunity to learn what was done right to avoid an accident or 
    incident in earlier situations. The likelihood of detecting problems 
    and developing remedies is significantly greater from studying large 
    numbers of normal daily operations than from relying primarily upon a 
    far smaller number of periodic inspections or accident and incident 
    investigations.
        Analysis of digital flight data can provide several types of 
    information, including aircraft path analysis, derivation of 
    environmental conditions, aircraft configuration time histories, 
    aerodynamic coefficients (analysis of coefficients can reveal 
    degradation in aerodynamic performance), engine performance, aircraft 
    attitude, automated flight control modes and status, warning 
    parameters, takeoff and landing distances, and flight loads. Digital 
    flight data can be used to detect single anomalies--alerting operators 
    when criteria values for selected parameters have been exceeded or when 
    particular events occur. Such data also can be used to develop 
    descriptive statistics across fleets, to detect deviations from 
    statistical norms in the aviation system, or to measure the effects of 
    design, procedure, or equipment changes.
        ATC automated data could be used to analyze airplane motion and 
    relative position, important factors in analyzing issues such as wake 
    vortex and environmental effects. An analysis of air traffic control 
    automated data for normal operations could provide insight into methods 
    for improving ATC system operations or potential problem areas. Flight 
    data anomalies from accidents could be compared to similar anomalies of 
    flights that did not crash to learn what was done differently to avoid 
    an
    
    [[Page 21524]]
    
    accident. These findings might suggest guidelines on pilot training or 
    aircraft design. The same autonomous ``intelligent agent'' analysis 
    techniques used to find patterns in data from incident reporting also 
    can be applied to digital flight data and ATC radar data--or 
    information derived from this data such as paths, flight loads, or 
    aerodynamic coefficients--to determine if any otherwise unobserved 
    associations exist within the data.
    
    Human Factors Analysis
    
        This analytical process and the new sources of data under 
    consideration could significantly improve our ability to describe what 
    is happening in the aviation system, and a comparable human factors 
    analysis capability must also be developed. Without a reliable human 
    factors analysis tool that addresses the underlying causes or factors 
    associated with emerging safety concerns, remedial measures may only be 
    temporary ``band aids.'' An effective human performance analysis 
    capability developed for use on digital flight data or ATC automated 
    data--augmented by feedback from voluntary disclosure systems--is an 
    essential part of an early warning system.
    
    A Proposed Architecture for Sharing
    
        As noted above, for a number of reasons, not the least of which is 
    the very large quantity of data, there will probably be little or no 
    sharing of raw data, but only of information from the analysis of data. 
    Moreover, because of improved networking technologies and capabilities, 
    information would not necessarily all be sent to a massive computer at 
    one location, but would probably be available to different users to 
    different extents by networking--sometimes known as a ``virtual 
    database.'' For example, this networking capability makes it possible 
    for each carrier, manufacturer, or union to have separate GAIN-type 
    systems, or they could do it collectively with one or more others or 
    through trade associations, or any combination of them, and the 
    information sharing could occur over the network to the extent desired 
    or permitted by the owner of each system.
        The information that results from GAIN analyses would ideally be 
    available immediately to all recipients who could use it to improve 
    aviation safety. The dissemination of vital information can be 
    accomplished with existing infrastructure--using the Internet, for 
    example, if adequate safeguards can be provided to protect the security 
    and confidentiality concerns of the information providers regarding 
    identified or identifiable data. The GAIN network would have to 
    accommodate different requirements in a user-friendly way, and be able 
    to notify automatically all appropriate recipients about potential 
    problems without requiring them to know to query the system.
    
    Examples of Proactive Use of Aviation Safety Data
    
        There are several examples in various countries that demonstrate 
    how effectively proactive safety measures can be implemented as a 
    result of industry/labor/government partnership sharing of such 
    information. When one air carrier's data indicated that pilots were 
    frequently disregarding their Ground Proximity Warning System (GPWS), 
    the carrier discovered that the frequent disregard was due to a high 
    false alarm rate, and further analysis of the data provided the basis 
    for developing a software remedy. As a result, that GPWS system was 
    improved (to the benefit of all carriers that used it), the false alarm 
    rate dropped, and pilots ignored the warning much less.
        Similarly, a carrier that was experiencing frequent altitude 
    capture excursions and deviations in one of its aircraft types found 
    from the data that the problem was a combination of inadequate pilot 
    training and poor altitude capture logic. Analysis of the data provided 
    the basis for improving both the training and the logic. Again, the 
    logic fix benefited all users of that autopilot around the world, not 
    just the carrier that discovered the problem.
        Other examples include improvements to training programs and/or 
    operations manuals as a result of high pitch angle takeoffs, more rapid 
    that desirable takeoff rotation rates, inadvertent flap/slat retraction 
    out of the proper speed range, and unstabilized approaches; design 
    fixes for equipment that did not perform as designed or anticipated 
    (e.g., an aircraft that was developing cracks from hard landings at 
    less than the 2 g cutoff beyond which inspection was mandated); and 
    improvements in airport signs and markings to help pilots more 
    accurately follow their taxi clearances.
        Also important, of course, is that without the data, it is very 
    difficult for carriers, manufacturers, or governments to evaluate 
    whether new programs and other fixes are having the desired result.
    
    Concept Implementation Issues
    
    Collection and Analysis of Aviation Safety Data
    
        In developing an analytical process for an early warning capability 
    that would monitor the system and alert the aviation community to 
    existing and emerging safety concerns, please consider what data 
    requirements, analysis methods, and information dissemination methods 
    you would propose. In relation to the analytical process, please 
    consider and comment on issues such as the following:
    
    -- What aviation safety data and information are needed to support your 
    analysis plan and what, of those needs, is not now being collected?
    --Should large quantities of data be collected on a wide range of 
    safety issues, or less data on fewer targeted safety issues?
    --To what extent is standardization of the data collection or of 
    analysis techniques necessary? How should the necessary standardization 
    be accomplished?
    --How could existing data, such as information from voluntary reporting 
    and correction, ASRS, AQP, FOQA, and other such programs, be analyzed 
    better to provide meaningful and useful information?
    --What could industry and government do to improve existing means for 
    data collection?
    --Are incentives needed to stimulate the submission of information that 
    is not derived from accidents or incidents, as opposed to merely 
    removing the disincentives, in order to encourage reporting?
    --To what extent can international information sharing occur with a 
    ``virtual database'' instead of a physically centralized data base?
    --What techniques and capabilities are you aware of in the aviation 
    industry or in other industries to analyze data effectively and 
    generate statistically significant results, with predictive value, from 
    large quantities of data describing normal operations?
    --What analytical techniques and capabilities are you aware of in the 
    aviation industry or in other industries to respond effectively to the 
    myriad of human factors issues that arise in operational monitoring 
    analysis?
    Dissemination of Aviation Safety Information
    --To what extent are security measures needed, and what security 
    measures are available, to protect information confidentiality while 
    still assuring that it reaches all in the industry who could use it to 
    improve aviation safety?
    --What alerting methods are available to ensure that information is 
    automatically distributed to all recipients who could use it to
    
    [[Page 21525]]
    
    improve aviation safety without their having to know to ask?
    General
    --Will an analysis and dissemination system such as GAIN help the 
    aviation industry reach Zero Accidents?
    --Are there better ways to help the industry reach Zero Accidents?
    --What concerns, if any, do you have about the existence of an analysis 
    and dissemination system such as GAIN?
    --What should the relationship be between government regulators and 
    GAIN for it to be most effective ?
    --Although commercial aviation is the initial target for this effort, 
    how can other sectors of the aviation industry, including the military, 
    help with this initial effort?
    --How can the program be expanded to include input from, and the 
    development of remedies in relation to information provided by, 
    manufacturing personnel, mechanics, flight attendants, dispatchers, 
    ramp personnel, and other aviation industry professionals whose input 
    could help with the proactive effort?
    
    Considerations for Developing Prototypes
    
    General
    
        Ultimately GAIN could develop into a comprehensive international 
    network of systems for analysis and sharing of aviation safety 
    information. However, that development would have to occur 
    incrementally, starting with one or more prototypes of various pieces 
    of the network. Among the areas that should be evaluated from prototype 
    development are: international data standardization, data collection 
    protocols, analytical methods, data sharing, alerting mechanisms, and 
    the potential value of emerging technologies. By prototyping key 
    elements of GAIN, it will be possible to obtain operational proof of 
    the most significant new capabilities being incorporated in this early 
    warning system. With a minimal initial commitment of resources, risks 
    and costs would be reduced, while allowing the overall operational 
    feasibility of the concept to be assessed. It would help define 
    obstacles and issues associated with the development of GAIN, and 
    provide valuable information for future implementation planning. 
    Because more types of data, more types of analyses, and more users 
    should not generally be added unless experience demonstrates that such 
    additions would be useful, prototypes would help to provide the 
    experience to determine the desirability of such additions.
    
    Ownership
    
        For several reasons, the elements of the GAIN network should 
    probably not be owned or operated by the FAA or the aviation regulatory 
    agency of any other country. Instead, they should probably be owned by 
    those members of the international aviation industry that benefit 
    economically from its successful performance, analogous to existing 
    collectively-owned, non-profit joint ventures in the aviation industry 
    that provide services for the owners' mutual benefit. There are several 
    reasons for pursuing this type of ownership. First, GAIN would probably 
    enjoy better acceptance by the industry if it is not viewed as a 
    government effort to gather information for enforcement purposes or to 
    protect its own manufacturers and carriers in an international 
    marketplace. Second, private ownership, as compared with governmental 
    ownership, would facilitate protecting sensitive information from 
    public disclosure. Third, the funding of GAIN should not depend upon 
    the fiscal situation in any one country.
        Last, but not least, GAIN's existence would be most assured, and it 
    would perform most effectively and efficiently, if it were owned 
    jointly by those who have a direct economic interest in its success--
    namely, the insurers, manufacturers, carriers, pilots, mechanics, 
    controllers, and airport operators that make up the industry. Either 
    GAIN will improve aviation safety and substantially reduce costs for 
    the entire industry--because prevention costs less than accidents--in 
    which event industry will want to own and operate it; or it will not 
    accomplish these goals, in which event a better way must be developed 
    to reach Zero Accidents.
        In determining how GAIN might be owned and structured, we invite 
    your comment about:
    
    --What types of prototypes could best demonstrate the concept at the 
    lowest cost, given existing data collection and analysis techniques and 
    capabilities?
    --What entities could help develop prototype projects, how much would 
    they cost, and what sources of funding are available?
    --What role can you play in the prototyping effort and subsequent 
    efforts to develop an operational GAIN?
    
    The Role of the FAA
    
        The FAA is already engaged in several activities to demonstrate, in 
    relatively small scale, the utility of safety data collection and 
    analysis, but the GAIN network and its prototypes would probably not be 
    FAA systems. The FAA's Office of System Safety could help facilitate 
    the creation of GAIN by informing potential participants about the 
    concept, and by bringing potential participants together, but the FAA 
    will not own or operate GAIN, and will probably not fund its 
    development. Instead, the FAA would be one of many users of the 
    analytical results and supporting data from GAIN.
        Given the numerous proactive accident prevention activities that 
    are already underway in various countries, it is likely that the 
    aviation industry would eventually develop an international cooperative 
    data sharing system, such as the GAIN network, on its own. The problem 
    has been that it is difficult for any one profession, manufacturer, or 
    airline to develop a program that systematically facilitates 
    international sharing of information to the benefit of the entire 
    international aviation community. Thus, in addition to facilitating 
    this development by demonstrating its intent to cooperate more with 
    industry to reach Zero Accidents, the FAA can play a major role in 
    accelerating the progress of private industry by bringing together the 
    entities that can help to develop GAIN prototypes--preferably by 
    building as much as possible upon the systems that are already in place 
    rather than starting anew--and by helping to assure that the prototypes 
    are sufficiently standardized and consistent to work together in the 
    more comprehensive GAIN network as it ultimately develops.
    
    Conclusion: A Call To Action
    
        Please let us know of your ideas regarding the development of a 
    GAIN network, particularly regarding how you can become involved, 
    either in a GAIN prototype or in the more comprehensive permanent 
    effort. This is not an invitation for bids or a request for proposals, 
    but we are soliciting indications of interest, as well as input 
    regarding the viability of this or any other concept to help the 
    industry reach Zero Accidents.
        You are encouraged to review the comments (Commenters will be able
