“The technical team has made an initial assessment of the data and we couldn’t be more pleased with the performance of the 787. The damping was as predicted and the pilots report that the airplane responded as expected.”
Tinseth added that the test data has been submitted to the FAA for validation as part of the type inspection authorisation, which will later see FAA officials join Boeing test engineers for certification testing on the aircraft.
To date the 787 test fleet has flown 118 test flights, accumulating 357 flight hours.
