Capt. Mike Bryan, Capt. Randy Neville and a crew of 11 flight
test personnel completed the first round of battery monitoring
tests today on board ZA005, the fifth 787 flight test airplane,
with a one hour and 29 minute flight. The flight departed from
Boeing Field at 10:17 am Pacific time and returned to Boeing
Field at 11:46 am Pacific time. The pilots report that today’s
flight was uneventful. 
This round of testing also included a flight on Saturday, which
lasted 2 hours and 19 minutes. Analysis of the test results will
continue in the days ahead. 
During the flight, the crew monitored the performance of the
main and APU batteries. Special equipment onboard ZA005, which
is currently the only member of the Boeing 787 flight test fleet
in service, allowed the crew to observe and record detailed
battery performance in normal flight conditions. 
Data gathered during the flight is considered part of the
investigations into the 787 battery events that occurred in
January. For that reason, we cannot share any additional
There are no additional flight tests planned for ZA005 at this
