COMPUTING
PROCEDURE
1.
Record the Basic Empty Weight and Moment from the
Basic Empty Weight and Balance form (or from the
latest
superseding
form) under the Basic Empty
Condition block. The
moment
must
be divided by
100
to correspond
to Useful Load Weights and Moments
tables.
2. Record the
weight
and corresponding moment from
the appropriate table of each of the useful load
items
(except
fuel) to be carried in the airplane.
3. Total the weight
column
and moment
column.
The
SUB-TOTAL is the Zero Fuel Condition.
4. Determine
the
weight
and corresponding moment for
the fuel loading to be used. This fuel
loading includes
fuel for the flight,
plus
that
required
for start, taxi, and
take-off. Add the Fuel to Zero Fuel Condition to obtain
the SUB-TOTAL Ramp Condition.
5.
Subtract the fuel to be
used
for start, taxi, and take-off
to arrive at the SUB-TOTAL Take-off Condition.
6. Subtract
the weight and
moment
of the fuel in the
incremental
sequence
in
which it is to be used from
the take-off
weight
and moment. The Zero Fuel Condi-
tion, the Take-Off Condition, and the Landing Condi-
tion
moment
must be
within
the
minimum
and maxi-
mum
moments shown
on
the
Moment Limit vs
Weight
graph
for that weight.
If
the total moment
is less
than
the
minimum
moment allowed, useful
load items must
be shifted aft
or
forward
load items
reduced.
If
the total
moment
is greater
than the
maximum moment
al-
lowed, useful load items must
be shifted forward or aft
load items reduced. If
the
quantity
or
location of load
items
is
changed,
the calculations must be
revised
and
the
moments
rechecked.
