Airlines are waiting to hear when they will receive their delayed next-generation B787 aircraft, after Boeing resumed flight tests last week.
The aircraft manufacturer was forced to ground all its Dreamliners after an electrical fault resulted in a fire on a test flight in November.
Boeing has now found an “interim” solution to the issue, and is installing updated power distribution system software.
Scott Fancher, vice president and general manager of the 787 program, said: "Initially, we will resume a series of Boeing tests that remain to be completed in the flight test program. That testing will be followed later by a resumption of certification testing.”
The new schedule for the delivery of aircraft is expected to be announced in January.
"As we return to flight test and determine the pace of that activity, we remain focused on developing a new program schedule," said Fancher.
