WEIGHT AND BALANCE
The following will enable you to determine the weight and balance of your aircraft
and to operate it within the prescribed center of gravity limitations.
The S-20 RAVEN is a simple aircraft and so are the weight and balance
calculations.
The S-20 RAVEN is limited to two occupants.
For baggage storage, a baggage compartment behind the seats is available.
The baggage compartment is rated for 80 lbs.
Baggage should be secured securely for flight.
To figure the weight and balance enter the following data on the chart. Refer to
FIGURE 12-01, FIGURE 12-01A
or
FIGURE 12-01B
.
•
Weight of Main Gear – Left.

Wing Fuel (at 6 lbs. / gal).
•
Header Tank Fuel (at 6 lbs. / gal).
•
Weight of Passenger.
•
Weight of Baggage.

Calculate the moments (Weight x Arm).
Add moments to obtain total moment.
Add weights to obtain total weight.
Calculate Center of Gravity.
(CG = Total Moment / Total Weight)
Check that the Center of Gravity calculated for take-off falls inside of the
acceptable Center of Gravity limits. Refer to
FIGURE 12-01, FIGURE 12-01A
or
FIGURE 12-01B
.
Repeat for landing configuration.
