TM 1-1510-225-10 3B-158 u.  FMS1 Data Loader Operation. (1)   Data   Loader   Operation   Overview.    The FMS-800   data   loader   provides   an   interface   to   data cartridges   for   data   storage   and   retrieval   capability.   The   data   loader   and   cartridge   allows   the   crew   to perform the following functions: 1.   Load     preplanned     flight     plans     and preset   information,   as   well   as   other flight data. 2.   Save   selected   flight   data,   including system status information. 3.   Access the ICAO identifier database. 4.   Load   a   200   waypoint   user   waypoint database. The   current   magnetic   variation   tables   can   be loaded     on     the     data     cartridge     and     automatically transferred    to    the    CDU    nonvolatile    memory    upon installation of the cartridge into the data loader.  If this file  already  exist  in  CDU  memory,  the  FMS-800  will compare the new file to the existing file and determine which  one  is  the  most  current.    If  the  new  file  is  the most current the FMS-800 will overwrite the old files. Access to data cartridge files is performed from the data loader pages or the start 3 page.  Points from the  ICAO  identifier  database  can  be  requested  from any page where waypoint entry is permitted.  Refer to Figure  3B-131   and   Table   3B-95  for  a  description  of how to access and use the Data Loader pages. (2)   Loading  Flight  Data.    The  following  data can be loaded from the data cartridge, if available. 1.   Any  one  of  40  alternate  flight  plans with    a    maximum    of    60    waypoints each.   2.   Markpoint and User Waypoint lists. 3.   GPS almanac data. 4.   Fifty-two V/UHF Communication radio presets,  HAVE  QUICK  II  MWOD,  and FMT lists. 5.   Navigation radio information (12 ILS/LOC frequencies). 6.   Airport communication frequencies. Most of these files can be loaded individually on the Data Loader pages. Figure 3B-131.  Data Loader Page Access and Usage Table 3B-95.  Data Loader Page Access and Usage NO.
