TM 55-1500-342-23 (27) Reference 24. Determine the ESTIMATED LANDING CONDITION by subtracting the weights and moments of Reference 22 from Reference 21 and adding reference 23. (28) Reference   25.      Enter   the   ESTIMATED LANDING   C.G.      as   determined   from   the   weight   and simplified moment values of reference 24. (29) The weight value from Reference 24 must be    compared    with    the    allowable    GROSS    WEIGHT LANDING    as    shown    in    the    LIMITATIONS    table    to ensure compatibility. Use the Reference 24 ESTIMATED   LANDING   CONDITION   gross   weight   to determine  the  PERMISSIBLE  C.G.    LANDING  forward and  aft  c.g.    limits  from  the  -10  operator's  manual  or Chart  E  loading  data.    If  the  ESTIMATED  LANDING C.G.  LANDING limits, enter them in the space provided in the LIMITATIONS table. (30) When the ESTIMATED LANDING CONDITION  of  Reference  24  and/or  the  ESTIMATED LANDING    C.G.        of    Reference    25    are    not    within permissible landing weight and/or c.g.  limits, changes in the   amount   of   distribution   of   load   and/or   fuel   are required.  A new Form F will be completed. (31) Enter  signature  of  person  computing  the form in COMPUTED BY SIGNATURE NOTE If local requirements exist for the use of the WEIGHT AND BALANCE AUTHORITY SIGNATURE    block    the    Commander    will establish policies and procedures. b.    Tactical. (1) Insert necessary identifying information at top of form. (2) Reference  1.    Enter  aircraft  basic  weight and moment/constant (or index). Obtain this information from last entry on Chart C. NOTE If   a   load   adjuster   is   used   in   loading   the aircraft, enter opposite Reference I the index figure obtained from Chart C and use index figures   throughout   the   form.      Enter   plate number of load adjuster  4-16    Change 2 (located on the left end of base) on the Form F.  If Chart E or -10 operator  manual  data  are  used  instead  of  a load adjuster, enter moment/constant values throughout the form. (3) Reference 2.  Leave blank (oil is included in basic weight). (4) Reference   3.      This   section   takes   into account all nonexpendable items not in the basic weight (and   not   otherwise   accounted   for).      Using   the   same compartment  letter  designation  as  shown  on  Chart  E (aircraft    diagram)    or    on    load    adjuster    enter    item description,   weight   and   moment   for   crew,   baggage, cargo, emergency equipment, racks, etc. (5) Reference  4.    Enter  sum  of  weights  and moments for Reference 1 through Reference 3 to obtain OPERATING WEIGHT. (6) Reference  5.    Enter  by  compartment  the item  description  (type,  number  of  rounds),  weight  and moment of all ammunition. (7) Reference    6.        Enter    item    description, weight  and  moment  of  all  other  expandable  ordnance such as bombs and rockets. (8) Reference  7.    Enter  number  of  gallons, weight  and  moment  of  fuel.    If  auxiliary  fuel  is  carried. make appropriate entries in space provided. (9) Reference    8.        Enter    item    description weight and moment of miscellaneous variables (such as water injection fluid). (10) Reference  9.    Enter  sum  of  weights  and moments  for  reference  4  through  reference  8  opposite TAKEOFF CONDITION (Uncorrected). (11) Reference   10.      Enter   TAKEOFF   C.G. (Uncorrected)  as  determined  from  weight  and  moment values of reference 9. (12) Enter    the    allowable    GROSS    WEIGHT TAKEOFF   and   GROSS   WEIGHT   LANDING   in   the LIMITATIONS table at the lower left-hand corner of the Form  F.    These  data  are  found  in  the  10  operator's manual and also in the Chart E loading data. (13) The  weight  value  from  reference  9  must be    compared    with    the    allowable    GROSS    WEIGHT TAKEOFF as shown in the LIMITATIONS table Change 2  4-16
