                              (AFF-FILE)
  
INFORMATION EFFECTIVE DATE: 4/26/1999  
    RECORD FORMAT: FIXED  
    LOGICAL RECORD LENGTH: 251  
 FILE STRUCTURE DESCRIPTION:  
---------------------------  
  
       THERE ARE A VARIABLE NUMBER OF FIXED-LENGTH RECORDS FOR EACH  
    AIR ROUTE TRAFFIC CONTROL CENTER FACILITY. THE AIR ROUTE TRAFFIC  
    CONTROL CENTER FACILITY FILE (ARTCC) CONTAINS ALL REMOTE AIR/GROUND  
    FACILITIES (RCAG), AIR ROUTE SURVEILLANCE RADARS (ARSR), SECONDARY  
    RADARS (SECRA), AND CENTER RADAR APPROACH CONTROL FACILITIES  
    (CERAP), UNDER U.S. AREA OF RESPONSIBILITY. THE FILE DOES NOT  
    INCLUDE ANY FOREIGN FACILITIES AND/OR RADARS.  
  
       THE NUMBER OF RECORDS IS DETERMINED BY:  
  
    1) THE AMOUNT OF TEXTUAL REMARKS PERTAINING TO THE AIR ROUTE TRAFFIC  
       CONTROL CENTER  
    2) FREQUENCIES AND THEIR USES ASSOCIATED WITH EACH AIR ROUTE  
       TRAFFIC CONTROL CENTER  
    3) THE AMOUNT OF TEXTUAL REMARKS PERTAINING TO FREQUENCIES AND THEIR  
       USES  
  
       THE RECORDS ARE IDENTIFIED BY A RECORD TYPE INDICATOR (AFF1,  
    AFF2, AFF3, AFF4), AND THE ARTCC CENTER IDENTIFIER, LOCATION, AND  
    FACILITY TYPE.  
  
       THE FILE IS SORTED BY CENTER IDENTIFIER,  
                             LOCATION,  
                             FACILITY TYPE,  
                             RECORD TYPE,  
                            (FREQUENCY,  
                             ASSOCIATED AIRPORT IDENT) - AFF3 RECORDS ONLY  

       EACH RECORD ENDS WITH A CARRIAGE RETURN CHARACTER AND LINE FEED 
    CHARACTER (CR/LF). THIS LINE TERMINATOR IS NOT INCLUDED IN THE LOGICAL 
    RECORD LENGTH.

  
DESCRIPTION OF THE RECORD TYPES:  
--------------------------------  
  
    'AFF1' RECORDS CONTAIN GENERAL DESCRIPTIVE LOCATION INFORMATION  
   
PERTAINING TO THE AIR ROUTE TRAFFIC CONTROL CENTER FACILITY. THERE  
    IS ALWAYS ONE 'AFF1' RECORD.  
  
    'AFF2' RECORD(S) CONTAIN(S) TEXTUAL REMARKS PERTAINING TO THE AIR  
    ROUTE TRAFFIC CONTROL CENTER FACILITY. THERE CAN BE 0 TO 50 'AFF2'  
    RECORDS.  
  
    'AFF3' RECORD(S) CONTAIN(S) THE COMMUNICATIONS FREQUENCIES AND  
    THEIR USES AS THEY ARE RELATED TO THE AIR ROUTE TRAFFIC CONTROL  
    CENTER FACILITY. THERE CAN BE 0 TO 50 'AFF3' RECORDS.

     1.  LEFT JUSTIFIED FIELDS HAVE TRAILING BLANKS  
     2.  RIGHT JUSTIFIED FIELDS HAVE LEADING BLANKS  
     3.  ELEMENT NUMBER IS FOR INTERNAL REFERENCE ONLY  
         AND NOT IN THE RECORD.  
     4.  THE UNIQUE RECORD IDENTIFIER IS MADE UP OF THE CENTER  
         IDENTIFIER, LOCATION, AND FACILITY TYPE.  
     5.  LATITUDE AND LONGITUDE INFORMATION IS REPRESENTED IN  
         TWO WAYS:  
         A.  FORMATTED:

            LATITUDE    DD-MM-SS.SSSH  
            LONGITUDE   DDD-MM-SS.SSSH  
  
            WHERE :     DD IS DEGREES  
                        MM IS MINUTES  
                        SS.SSS IS SECONDS  
                        H IS DECLINATION

                        LONG-  075-27-54.660W  
  
          B.  IN ALL SECONDS:  
             -----------------  
             LATITUDE AND LONGITUDE     SSSSSS.SSSH  
             WHERE :    SSSSSS.SSS IS THE DEG/MIN/SEC CONVERTED  
                                   TO ALL SECONDS  
                        H IS THE DECLINATION  
  
             EXAMPLE :  LAT-   140811.070N
