Pan American Operational Experience with STAN

STAN is the on-board weight and balance system presently used by Pan American on its cargo aircraft. Based on 1-1/2 years of operational experience as a secondary or check system to the weight and balance manifest, STAN has substantially justified itself through its accuracy and reliability. Its success suggests the feasability of developing a primary weight and balance system, which would be of significant value, especially on the forthcoming supersonic and jumbo jets.
