Is the weight and balance calculator approved by the FAA for use by Air Carriers?
It is up to each individual Flight Standards District Office (FSDO) to determine if the weight and balance control calculation system being used by a 121, 125, or 135 operator is valid and accurate. If the Principal Maintenance Inspector (PMI) or Principal Operations Inspector (POI) feels that they cannot adequately determine the validity of a system, they are supposed to bump it up to the regional engineering office for examination. American Aeronautics has been approved by every FSDO in the U.S. at least once, most many times.
