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.

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.
