5.5 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)].
(1)
Basic Empty
Weight
3122 lbs.
(2) Occupants
(2
x 170
lbs] 340 lbs.
(3)
Baggage
and Cargo
27 lbs.
(4)
Fuel (6
lb./
gat
x
80)
480 lbs.
(5) Takeoff Weight
3969 lbs.
(6) Landing
Weight
ta)(5)
minus
(g)(!),
(3969 Ibs.
minus
314 lbs
)
3655 lbs.
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.
