Spectrums boast low emissions

Spectrum Aeronautical (Booth No. 1947) has quantified the CO2 that will be generated by its Freedom S-40 and Independence S-33 business jets and compared those to competing jets to see how the Spectrum jets stack up emissions-wise. On a 600-nm flight, the midsize S-40 generates slightly less than 1,500 kilograms of CO2, according to Spectrum, while comparable jets should generate more than 2,000 kilograms to nearly 4,000 kilograms. The Williams FJ33-4A-powered S-33 light jet puts out about 1,100 kilograms and the nearest competitor in emissions totals should generate a little more than 1,400 kilograms. The most inefficient jet in that class reaches about 2,100 kilograms of CO2, according to Spectrum.

“By having a very light airplane to begin with, it requires less thrust,” said Spectrum vice president Mark Jones. The Spectrum jets are all-composite and built using a technique that makes them 40 percent lighter than competing aluminum jets, according to Spectrum.
