METHODS OF TESTING A MONUMENT THAT IS TO BE ATTACHED TO A FLOOR OF AN AIRCRAFT

Methods of testing a monument that is attached to a floor of the aircraft. The testing uses a compliance matrix based on attachment points where the monument is attached to the floor of the aircraft. The testing uses a test monument that is equipped with extension members and load cells positioned at the corresponding attachment points.
