TM 55-1500-342-23 to   ensure   it   is   within   limits.      Use   the   reference   9 TAKEOFF  CONDITION  (Uncorrected)  gross  weight  to determine  the  PERMISSIBLE  C.G.    TAKEOFF  forward and   aft   c.g   limits   from   the   -10   operator's   manual   or Chart E loading data.  If the takeoff c.g.  of reference 10 is  within  these  PERMISSIBLE  C.G.    TAKEOFF  limits, and no other corrections are necessary, (i.e.  temporary equipment  changes),  enter  the  permissible  limits  in  the space   provided   in   the   limitations   table.      Enter   the uncorrected  weight  and  c.g.    values  from  reference  9 and  reference  10  into  the  blocks  at  reference  12  and reference 13 respectively. NOTE The  c.g.    charts  and  tables  in  the  Chart  E and  -10  operator's  manual  are  not  accurate enough to use near the forward and aft c.g. limits.    In  those  instances  when  the  actual c.g.    is  very  close  to  the  aircraft  limits,  the c.g.      must   be   arithmetically   calculated   to ensure the necessary accuracy. (14) Reference  11.    When  the  takeoff  weight of  reference  9  and/or  the  takeoff  c.g.    of  reference  10 are   not   within   permissible   takeoff   weight   and/or   c.g. Limits,  changes  in  the  amount  or  distribution  of  load (reference  3  through  reference  8)  are  required.    The necessary    load    adjustments    must    be    noted    in    the CORRECTIONS columns on the left-hand portion of the Form F.  Enter a brief description of the necessary load adjustment  in  the  left-hand  column  with  the  weight  and moment  listed  in  the  columns  provided.    Sum  all  the weight   and   moment   increases   and/or   decreases   to obtain    the    net    change    (+    or-)    in    the    amount    or distribution  of  the  load.    Transfer  the  total  weight  and moment     adjustment     to     the     spaces     provided     for CORRECTIONS (If required) at reference 11. NOTE If     there     are     any     temporary     equipment changes  listed  on  DA  Form  2408-13-12408- 13-1-E  or  DA  Form  2408-1412408-14-E,  they shall    be    considered    changes    in    aircraft loading.      These   changes   shall   be   entered with  the  notation  "EQUIPMENT  CHANGES" near the top of the CORRECTIONS table.  A brief    description,    weights    and    moments shall  be  entered  in  the  columns  below  this notation.  These entries shall be treated as a variation  in  loading  and  applied  to  the  total entered in reference 11. (15) Reference  12.    In  the  space  provided  for TAKEOFF  CONDITION  (corrected),  enter  the  sum  of reference  9  and  reference  11.    (Add  if  reference  11  is positive.    If  it  is  negative,  subtract  reference  11  from reference 9). (16) Reference 13.  Enter the TAKEOFF C.G. (Corrected), as determined from the weight and moment values of reference 12. (17) The weight value from reference 12 must again be compared with the allowable GROSS WEIGHT TAKEOFF   as   shown   in   the   LIMITATIONS   table   to ensure  compatibility.    At  the  reference  12  TAKEOFF CONDITION (Corrected) gross weight, again determine the PERMISSIBLE C.G.  TAKEOFF forward and aft c.g. limits from the -10 operator's manual or Chart E loading data.      Recheck   the   takeoff   c.g.      of   reference   13   to ensure  it  is  within  the  PERMISSIBLE  C.G.    TAKEOFF limits.    Enter  these  limits  in  the  space  provided  in  the LIMITATIONS table. (18) Reference 14.  Determine total TAKEOFF FUEL weight and moment from reference 7 and enter in reference  14.    List  weight  and  moment  of  expendable items  such  as  ammunition  (not  including  the  weight  of cases    and    links    if    retained),    bombs,    rockets,    and external  fuel  tanks  that  are  to  be  dropped  during  flight. Explain  under  REMARKS,  if  necessary.    These  items listed  as  LESS  EXPENDABLES  are  considered  part  of reference 14. (19) Reference 15. Determine the ESTIMATED  LANDING  FUEL  weight  and  moment  and enter it in the space provided. (20) Reference 16. Determine the ESTIMATED  LANDING  CONDITION  by  subtracting  all of the expendable weights and moments of reference 14 from  the  reference  12  weight  and  moment  and  adding the weight and moment of reference 15.  The use of a minus sign (-) before the reference 14 entries and a plus sign  (+)  before  the  reference  15  entry  helps  prevent errors in completing this step. (21) Reference   17.      Enter   the   ESTIMATED LANDING   C.G.      as   determined   from   the   weight   and simplified moment values of reference 16. Change 7  4-17
