The Society of Allied Weight Engineers (SAWE) goals are to promote mass properties engineering as a specialized discipline and to provide a means for those interested in mass properties engineering to work together to further their professional goals. Since it's inception in 1939, the SAWE has grown to include 22 chapters located in the United States, Brazil, Canada, Central Europe, India, and the United Kingdom and has members from over 22 countries. The Society promotes technical interchange between its members through international and regional conferences, the Weight Engineering Journal, specialized training, technical papers and a growing number of professional publications.

Candidates for International Office

The SAWE is actively seeking nominations for for SAWE International Offices of President, Executive Vice President, and Senior Vice President. Nominations are due by November 30, 2014.

The SAWE is now ANSI Accredited

August 10, 2014


 The SAWE is now ANSI Accredited

The Society of Allied Weight Engineers is very pleased to announce that it is now an Accredited Standards Developer (ASD) as administered by the American National Standards Institute (ANSI).  We were officially provided that status in July of this year [2014]. This means that our society can create standards which will be distributed as ANSI/SAWE Standards.  As ANSI is a member body of the International Standards Organization (ISO), SAWE Standards can also be considered for ISO accreditation during their development process.  To understand the SAWE process required to create an ANSI standard see the freely available publication, Technical Overview document TO-2, “SAWE Procedures as an Accredited Standards Developer with the  American National Standards Institute”  The SAWE Standards and Practices Committee hopes that this achievement provides our members and sponsors increased membership value, and stands ready to work with you in advancing the field of Mass Properties Engineering through generation of quality ANSI/SAWE standards.

Updated - SAWE Response to FAA Advisory Circular (AC) 120-27E


June 16, 2014

The Federal Aviation Administration (FAA) published draft Advisory Circular (AC) 120-27F “Aircraft Weight & Balance Control” for comment on November 7, 2013.  We, the Society of Allied Weight Engineers (SAWE), responded in the FAA open period in January 2014 by volunteering to lead an industry solution in the establishment of standard crew, passenger, and baggage weights, and respectfully submitted a response to the FAA.  

On June 11, 2014, SAWE learned that the FAA will be updating the draft AC120-27F to use …“the latest NHANES Data for standard <passenger> weights, the other options will also still remain the same.  Once the changes have been completed it will go out for public comment again.”.

No further details were stated.  So stay tuned for another version of AC120-27F in the near future.
