FLIGHT PLANNING EXAMPTE
(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 by Section
6
(Weight
and
Balance)
bf
this handbook.
The basic empty weight
for
the airplane
as
licensed at the factory
has been enter 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
nrade
to
deterntine the current
basic entpty weight of the airplane.
Make use of the Weight
ancl Balance Loading
Form (Figure 6-11) and the C.G.
Range and
Weight graph (Figure 6-15) to cletermine the total weight of the airplane and the center of gravity
position.
After proper utilization of the information provided,
we have found the following weights
for consideration in the flight planning
example.
The landing weight cannot be determined
until
the weight of the fuel
established
Iref'er
to item

Takeoff Weight

Landing Weight
(a)(5) minus
(g)(l),
(2400lbs. minus
129 lbs.)
to
be used has
been
14l2lbs.
340 lbs.
360 lbs.
288 lbs.
2400
lbs.
2271lbs.
Our takeoff weight is below the maximum
of
2550
lbs. and our weight and
balance
calculations have determined
or,rr
C.G.
position within the approved limits.
(b)
Takeoff and Landing
Now that we
have deterrninecl
our aircraft loading,
we
must consider all
aspects
of
our
takeoff and landing.
All of
the existing conditions at the departure and destination airport must
be acquired,
evaluated and maintained
throughout
the
flight.
Apply the departure airport conditions and takeoff weight
to
the appropriate Takeoff
Performance graph (Figure 5-5 or
5-7),
to
determine the length
of
runway
n€:cessary
for
the
takeoff and/or the barrier distance,
The ianding distance calculations are perforrnecl
in
the
same
n)anner using the existing
conditions at the destination airirort and,
wher-r
established, the landing weight.
