Boeing, NASA, and German Aerospace Center DLR have commenced flight tests on Thursday with a MAX 10 and Douglas DC-8 to study the effects of burning sustainable aviation fuels (SAF) on contrail formation and non-carbon emissions. Testing should demonstrate if there are any side effects from using SAF.
During the test flight, NASA’s DC-8 Airborne Science Lab was trailing the MAX 10 at some distance and taking measurements from the exhaust gasses. The Boeing was using 100 percent SAF on one CFM LEAP-1B engine and conventional kerosene on the other the check for any differences.
The MAX 10 used for the test is the third production aircraft with Line Number 8634 and Manufacturing Serial Number 43510 that is destined for United Airlines once the type has been certified (see main picture by Jennifer Schuld). The aircraft first flew on September 14. For now, the aircraft will be used by Boeing as the second ecoDemonstrator
Explorer.
