Boeing’s third 777X airplane took to the sky on Monday. The plane, N779XY, took to the skies at 13:55 PDT from Everett and returned to Boeing Field at 16:42 PDT, stopping at Moses Lake in the process.
Designated WH003, this airplane is the third of four in a dedicated flight test fleet.
“We continue to execute our robust test programme for the 777-9, which began flight testing in January,” the company said on 4 August. The airframer adds that it is “pleased with the progress” it is making with the test programme, without publishing any further details.
This airframe is slated to conduct tests related to the avionics system, auxiliary power unit, flight loads and propulsion performance, Boeing says. It is painted in Boeing’s new “light livery”, which the company adopted in 2018.
The 777X is touted as the successor of the iconic Boeing 747 with a range of up to 8,730 nautical miles.
