INFORMATION EFFECTIVE DATE: 11/25/2004  
 
    RECORD FORMAT: FIXED  
    LOGICAL RECORD LENGTH: 699  
 
  
FILE STRUCTURE DESCRIPTION:  
--------------------------  
    THERE ARE A VARIABLE NUMBER OF FIXED LENGTH RECORDS FOR  
    A SINGLE NAVIGATIONAL AID (NAVAID). THE NUMBER OF RECORDS IS  
    DETERMINED BY THE REMARKS, AIRSPACE FIXES, HOLDING PATTERNS, AND  
    FAN MARKERS RELATED TO EACH NAVAID.  
    THE RECORDS ARE IDENTIFIABLE BY A RECORD TYPE INDICATOR, (NAV1,  
    NAV2, NAV3, NAV4, NAV5), THA NAVAID FACILITY  
    LOCATION IDENTIFIER, AND THE NAVAID FACILITY TYPE.  
  
    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.

    THE FILE IS SORTED BY STATE, CITY, NAVAID NAME, AND FACILITY  
    LOCATION IDENTIFIER.  
  
  
DESCRIPTION OF THE RECORD TYPES:  
-------------------------------  
    THE 'NAV1' RECORD TYPE CONTAINS BASIC NAVAID INFORMATION.  
    THERE IS ALWAYS A NAV1 RECORD.  
  
    THE 'NAV2' RECORD WILL CONTAINS ONE 400 CHARACTER REMARK  
    PERTAINING TO THE PRECEEDING NAV1 RECORD.  
  
    THE 'NAV3' RECORD WILL CONTAINS THE COMPULSORY AND NON-COMPULSORY  
    AIRSPACE FIXES ASSOCIATED WITH THE PRECEDING  
    NAV1 RECORD.  THE RECORD IS PADDED TO ALLOW FOR A MAXIMUM  
    OF 18 - 33 CHARACTER FIX ENTRIES.  
  
    THE 'NAV4' RECORD TYPE CONTAINS THE HOLDING PATTERNS ASSOCIATED  
    WITH THE PRECEDING NAV1 RECORD.  THE RECORD IS PADDED TO ALLOW  
    FOR A MAXIMUM OF 18 - 33 CHARACTER HOLDING PATTERN ENTRIES.  
  
    THE NAV5 RECORD TYPE CONTAINS THE FAN MARKERS ASSOCIATED WITH  
    THE PRECEDING NAV1 RECORD.  THE RECORD IS PADDED TO ALLOW FOR A  
    MAXIMUM OF 23 - 26 CHARACTER FAN MARKER ENTRIES.  
  
    EACH NAV1 RECORD MAY HAVE NONE, ONE OR MANY ASSOCIATED NAV2,  
    NAV3, NAV4 OR NAV5 RECORDS.  EACH NAV1, NAV2, NAV3, NAV4, AND  
    NAV5 RECORD CONTAINS THE BASIC NAVAID IDENTIFYING INFORMATION  
   
(NAVAID FACILITY LOCATION IDENTIFIER AND THE NAVAID FACILITY TYPE).  

GENERAL INFORMATION:  
-------------------  
    1.  LEFT JUSTIFIED FIELDS HAVE TRAILING BLANKS  
    2.  RIGHT JUSTIFIED FIELDS HAVE LEADING BLANKS  
    3.  ELEMENT NUMBER IS FOR TERMINAL REFERENCE ONLY  
        AND NOT IN THE RECORD.  
    4.  THE UNIQUE NAV ID (ELEMENT NUMBER: DLID) IS MADE UP OF  
        THE FACILITY IDENT, THE FACILITY TYPE CODE, AND THE CITY.  
    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  
            EXAMPLE:     LAT-    39-06-51.070N  
                         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  
                     LONG-    27164.66W
