    ACTION: Notice of policy statement.

    SUMMARY: The American people have demanded a smaller, more efficient 
    government; toward that end, the resources of the National Airspace 
    System must be streamlined and service provided in a safe yet 
    economical way. In November 1994, senior management officials from the 
    Federal Aviation Administration (FAA) and the National Weather Service 
    (NWS) met with executives from fourteen national aviation associations 
    concerning surface aviation observation services. They reached an 
    agreement that the government would work with industry to define 
    various support levels for surface observations.
        In addition, in March 1995, and in accordance with the Office of 
    Management and Budget (OMB) policy, the FAA began the process to assume 
    responsibility for aviation surface weather observations beginning in 
    FY 1996. As the NWS automates field offices and reallocates their 
    personnel under this plan, the FAA will undertake accountability for 
    observations at many NWS ASOS sites. The NWS has begun transitioning 
    these ASOS sites to the FAA as the ASOSs are commissioned and has 
    solicited public comment (61 FR 19595; May 2, 1996). The FAA also 
    expanded by more than two hundred, the sites to receive ASOSs, thus 
    enhancing safety at sites without weather observations. All of these 
    activities prompted the FAA to take aggressive action in addressing 
    surface aviation observation requirements and do it within modest 
    resource gains.
        As a result, a government/industry team has worked for a year and a 
    half to comprehensively reassess the requirements for surface 
    observations at the nation's airports. That work has resulted in 
    agreement on a set of service standards as well as the FAA and NWS 
    Automated Surface Observing System (ASOS) sites to which the standards 
    will apply. This notice outlines the four kinds of service, explains 
    the method used to determine which airports receive which type of 
    service, and contains a listing of the airports and the service 
    categories in which they fall. The FAA, NWS and Industry 
    representatives believe the service standards approach supports the 
    best allocation of scarce resources.

    SUPPLEMENTARY INFORMATION: The term Service Standards refers to four 
    levels of detail in the weather observation at sites where there is a 
    commissioned ASOS. The first category, known as Service Level D, is 
    completely automated service, at which the ASOS observation will 
    constitute the entire observation, i.e., no additional weather 
    information is added by a human weather observer. A partial list of the 
    airports that fit in this category are provided at the end of this 
    Notice. Some of these airports currently have contract weather 
    observers providing the service. Many other sites (60-80) will be 
    expanded to include automated systems; they are currently under review. 
    Information on specific additional sites is available upon request.
        The second category, tower-augmented service, also known as Service 
    Level C, encompasses approximately two hundred and fifty airports. At 
    this level, a human observer adds additional information to the 
    automated observation. Augmentation includes the following parameters: 
    thunderstorms, tornadoes, hail, virga, volcanic ash, and tower 
    visibility. In addition, in the event of an ASOS malfunction or the 
    ASOS reporting unrepresentative data, the human observer may insert the 
    correct value or more representative information into the observation. 
    This is referred to as backup.
        Backup consists of inserting the following parameters where 
    available: wind, visibility, precipitation/obstruction to vision type, 
    cloud height, sky cover, temperature, dewpoint and altimeter setting. 
    This level of service would be provided at all towered airports during 
    hours of operation. During hours that the tower is closed, the ASOS 
    will provide observations without backup or augmentation. These 
    airports are listed as tower-agumented (Service Level C) airports at 
    the end of this notice. Although this category is listed as tower-
    agumented, the service may be provided by Flight Service Stations at 
    selected sites.
        At 135 airports, adding more detail to the weather observation was 
    considered optimum. These airports were divided into two categories, 
    major aviation hubs and high traffic volume airports with average or 
    worse weather, referred to as Service Level A airports; and the 
    remaining group of airports that are smaller hubs or special airports 
    in other ways, that have worse than average bad weather operations for 
    thunderstorms and/or freezing/frozen precipitation, and/or that are 
    remote airports, referred to as Service Level B airports.
        Service Level B airports will receive augmentation and backup (C-
    level service) plus long-line Runway Visual Range (RVR), which may be 
    an instantaneous readout. If observed, the following elements will be 
    added to the observation: freezing drizzle versus freezing rain, ice 
    pellets, snow depth and snow increasing rapidly remarks, thunderstorm/
    lightning location remarks and observed significant weather not at the 
    station remarks. At selected airports in this category, during
    
    [[Page 32888]]
    
    hours of low traffic volume, the service may revert to Service Level C, 
    tower-augmented service, or Service Level D, automated service.
        Service Level A airports will receive, in addition to the services 
    described above, 10 minute long-line RVR or additional visibility 
    increments of \1/8\/, \1/16\ and 0. If observed, the following elements 
    will be added to the observation: sector visibility, variable sky 
    condition, cloud layers above 12,000 feet and cloud types, widespread 
    dust, sand and other obscurations and volcanic eruptions.
        At selected sites, Flight Service Stations may do the support at 
    Level A, B, or C airports. In lieu of a contract of NWS observer at a 
    Level A, B or C airport, a non-government entity, such as a Fixed Base 
    Operator or commercial aviation operator may agree to provide 
    augmentation or backup to the ASOS observation, at no cost to the 
    government. On a case-by-case basis, arrangements can be made to 
    install an operator interface device, provide training materials, and 
    determine a payment schedule for any recurring costs associated with 
    the activity.
        More detailed information on Service Standard procedures, including 
    augmentation and backup, is contained in FAA Order 7900.5A. This 
    document is available upon request.
    
    Implementation Schedule
    
        The date for implementation of Service Standards for each airport 
    will be based upon a number of factors, including NWS transition dates, 
    ASOS commissioning dates and the FAA budget. Sufficient budget for 
    implementing Service Levels has been requested for FY 97. However, FAA 
    budget resources are insufficient in FY 96 to fully fund observations 
    at the A and B Service Levels at all sites designated for those Service 
    Standards. For Level 5 towered sites, the FAA has already allocated 
    funds for Service Level A support to begin immediately upon 
    commissioning of ASOS; those sites are identified by an asterisk in the 
    list at this end of this Notice.
        The implementation date will be included in a Notice to Airmen and/
    or in the Airport/Facility Directory when transition is imminent. 
    Information on the schedule for specific sites is available on request.
    
    Ranking Process
    
        The criteria used to rank the airports were based on (1) occurrence 
    of significant weather weighted by traffic counts; (2) distance to the 
    nearest suitable alternate airport; and (3) critical airport 
    characteristics. These criteria produced a score for each airport which 
    determined their level of service. Seventy-eight ASOS sites have the 
    greatest augmentation needs and will receive expanded service (Level 
    A); fifty-seven to receive enhanced service (Level B); two hundred and 
    fifty to receive tower augmentation (Level C); and another nearly four 
    hundred to receive automated service (Level D). The composite scores 
    assigned were solely based on weighted objective criteria designed to 
    capture critical airport characteristics as follows.
    
    Bad Weather Operations Score
    
        This score is calculated by (1) adding the percentage of times that 
    the airport is impacted by thunderstorms, freezing and/or frozen 
    precipitation (including freezing rain, freezing drizzle, snow, snow 
    pellets, snow squalls, snow showers, ice pellets, ice pellet showers, 
    ice crystals), and visibility less than or equal to .5 mile and 
    multiplying that percentage sum times total operations at that airport; 
    (2) multiplying the percentage of time the airport experiences 
    visibility less than or equal to 3 miles times the number of all 
    operations and then multiplying that figure by .5; (3) summing the 
    figures from steps 1-2 above; and (4) setting the resultant figures to 
    a linear scale ranging from 0 to 18. The total score range was set at 0 
    to 18 to coincide with the combined total score range of the airport 
    characteristics and the alternate airport criteria as described in the 
    next two paragraphs. The traffic count data utilized is FY 1994.
        For sites that did not have any weather information available, an 
    alternate method was devised to compute weather scores. Each airport 
    which had a composite score of 2 or more, even without weather data, 
    was assigned weather information (surrogate weather) from the nearest 
    airport with similar weather. This step was omitted for airports with a 
    non-weather composite score of less than 2 because adding even a high 
    weather score to such sites would not cause them to need expanded 
    service. A list of these airports and the surrogate weather utilized 
    for them is available upon request.
    
    Score for Distance to Nearest Suitable Alternate Airport
    
        This score gives credit for airports for which the nearest suitable 
    alternate is a greater distance away. Where available, these alternates 
    were selected from an Air Transport Association-provided list of actual 
    alternates utilized for certain airports. Otherwise, an automated 
    approach was used to determine these alternates based on the following 
    requirements
         The alternate site must have some observation 
    capabilities. It must be an FAA or NWS ASOS site; an FAA or NWS 
    contract weather observer observation site; a Federal or Non-Federal 
    Automated Weather Observing Site (AWOS) site; or a Supplementary 
    Aviation Weather Reporting Site (SAWRS) station.
         If the destination airport has a Terminal Airdrome 
    Forecast (TAF) issued, the alternate site must have a TAF issued also.
         If the destination airport is a Part 139 airport, the 
    alternate site must be a Part 139 airport also.
        The scoring was done using Table 1.

    Airport Characteristics Score
    
        This score is given based on the applicability of the scores in 
    Table 2. The tower levels are those established as 3/11/96.

    ------------------------------------------------------------------------
    
    Ranking
    
        The scores from the three areas described above were then added 
    together and each airport was assigned a composite score and ranked 
    accordingly. Information on the process of determining the exact 
    boundaries between service levels, as well as scores for individual 
    airports, are available upon request.
        This following list includes the service level categories and the 
    airports that fall into each category. The airports in each service 
    level category are listed by state and the city where the airport is 
    located. The airport's three letter location identifier is also 
    included. For
