The test flights involved a year of preparation and many partnerships

Embraer Executive Jets recently conducted flight tests on two of its aircraft using 100 percent sustainable aviation fuel (SAF). The Brazilian airframer flew its demonstrator Phenom 300E and its prototype Praetor 600 at its U.S. headquarters in Melbourne, Florida, at the end of September after a year of preparations.

As a safety measure, both of the twinjets—which have separate fuel tanks supplying each engine—flew with one engine running on conventional jet-A while the other used unblended SAF.
