## CS 23.2100 Mass and centre of gravity

(a) The applicant must determine limits for mass and centre of gravity that provide for the safe operation of the aeroplane.

(b) The applicant’s design must comply with each requirement of this Subpart at critical combinations of mass and centre of gravity within the aeroplane’s range of loading conditions using acceptable tolerances.

(c) The condition of the aeroplane at the time of determining its empty mass and centre of gravity must be well defined and easily repeatable.
