S-7S WEIGHT AND BALANCE
INTRODUCTION
This Section describes the procedures for establishing of basic empty weight and
moment of the airplane.
Procedures for calculating the weight and moment for various loadings are also
provided. Sample forms are provided for reference. Refer to
FIGURES 10-01
AND 10-01A in the FIGURES manual.
Always check your weight and balance during your pre-flight planning. It is
recommended to check the data for landing and take off (fuel weight change).
It is the responsibility of the pilot to ensure that the airplane is loaded properly.

•
Drain all fuel
•
Service engine oil as required to obtain a normal indication
•
Move seats to the most aft position
