Sagrad has spent four years collaborating with NASA, the Air Force, DARPA and the FAA to develop our first multipurpose AFTU which is now in flight qualification.
Initial qualification testing was completed in late-2018. Technical performance through the test sequence revealed no performance issues.
Final inspection uncovered a mechanical issue isolated to one specific component – a through-hole capacitor. We have chosen to improve the design with an appropriate surface-mount capacitor, with no other changes to the current design. This improved board design will be part of a new series of qualification tests; there is high confidence in the successful completion of this qualification based on the success of the initial qualification.
New qualification units are being prepared and new qualification tests are planned to begin in early Q2 2019. Completion of qualification is anticipated near the end of Q2 2019.
