Aircraft Energy Efficiency

OBS: The well known ACEE (Aircraft Energy Efficiency) program in the United States emerged from the fear of substantial increases in future fuel costs. The slogan was ""reduced weight for reduced fuel cost"". to achieve high performance, some designs called for individually tailor-made plies which saved a mere ounce at a substantial cost penalty. Instead of the cost of fuel increasing as predicted, it has actually dropped considerably (in real dollars) since the early 1980s, and the demand for high performance has somewhat diminished. Consequently, the ACEE program has lost much of its funding and clout.
