The stretched Boeing 787-9 took off on its maiden flight from Paine Field in Everett, Washington, at 11:03 local time today.
The aircraft, known as BOE001, departed from runway 34L for its four- to five-hour flight over mostly Washington state before it returns to Boeing Field in Seattle. The flight was initially scheduled to depart around 10:10 local time.
Captains Mike Bryan and Randy Neville are at the controls of the aircraft for the flight today.
The test aircraft is powered by two Rolls-Royce Trent 1000 package C engines, which are rated at 74,000lb-thrust.
The 787-9 is 6m longer than its older sibling the 787-8, which allows it to carry 40 more passengers. It can also fly 300nm (555km) further than the smaller variant.
The first flight keeps with Chicago-based Boeing’s schedule of delivering the first -9 to launch customer Air New Zealand by the middle of 2014. This is an about face from the 40-month delay that faced the -8.
The airframer has applied the various design and supply chain lessons that it learned from the -8 to the -9 programme with apparent success.
Boeing has 389 firm orders for the 787-9, Flightglobal’s Ascend Online database shows.
