6.4 -- DETERMINING WEIGHT AND BALANCE
GENERAL
This paragraph is intended to provide the pilot with a simple and rapid means
of determining weight and balance of his airplane.
IT IS THE PILOT’S RESPONSIBILITY TO ENSURE THAT THE AIRPLANE
IS LOADED PROPERLY AND THE WEIGHT AND BALANCE LIMITS ARE
ADHERED TO.
Empty weight to be considered is the weight noted on last weighing form. To
this empty weight corresponds a basic balance, expressed in percent of
mean aerodynamic chord. Empty weight and the corresponding balance
allow to calculate the airplane basic index.
If airplane empty weight has varied since last weighing form, refer to
paragraph ”DETERMINING EMPTY AIRPLANE CHARACTERISTICS” to
determine new empty weight and the corresponding balance (for instance :
optional equipment installation).
