FLIGHT
PLANNING
EXAMPLE
(a)
Aircraft
Loading
The
first
step
in
planning
the
flight is
to
calculate
the
airplane
weight
and
center
of
gravity
by
utilizing the
information
provided
bv
Section 6
(Weight
and
Balance)
of
this handbook.
The
basic
empty
weight
for
the
airplane
as
licensed
at
the
factory
has
been
entered
in
Figure 6-5.
If
any
alterations
to
the
airplane
have
been
made
effecting
weight and
balance,
reference
to
the
aircraft
logbook
and
Weight
and
Balance
Record
(Figure 6-7)
should
be
made
to
determine
the
current
basic
empty
weight of
the
airplane.
Make
use
of
the
Weight and Balance
Loading
Form
(Figure
6-11)
and
C.G. Range
and
Weight graph
(Figure
6-15)
to
deter-
mine
the
total
weight
of
the
airplane
and
the
center
of
gravity
position.
The
landing
weight
cannot
be
determined until the
weight ofthe
fuel
to
be
used
has
been
established
[refer
to
item
(g)(1)].

The
takeoff
and
landing
weights
are
below the
maximums
and
the
weight
and
balance
calculations
have
determined that
the
C.G.
position
is
within
the
approved
limits.
(b)
Takeoff and
Landing
Apply the
departure
airport
conditions
and
takeoff
weight
to
the
appropriate
Takeoff
Performance
and Accelerate and
Stop
Distance
graphs
(Figures
5-7
thru
5-15)
to
determine
the
length
of
runway
necessary
for the
takeoff
and
or
the
barrier distance.
The
landing
distance
calculations
are
performed in
the
same
manner
using
the
existing
conditions
at
the
destination
airport and,
when
established,
the
landing
weight.
