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.

NOTE: both trike and

taildragger versions are available 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 takeoff due to fuel weight
change.

It is the responsibility of the pilot to ensure that the airplane is loaded properly.
