Second Boeing 777X Completes First Flight
1588290387400.png

EVERETT, Wash., April 30, 2020-- Boeing [NYSE: BA] today conducted a productive and successful first flight of the second 777X airplane. Capt. Ted Grady, 777X project pilot, and Capt. Van Chaney, 777/777X chief pilot, flew for 2 hours and 58 minutes over Washington state before landing at Seattle's Boeing Field at 2:02 p.m. Pacific.

Designated WH002, this airplane is the second of four in a dedicated flight test fleet and will test handling characteristics and other aspects of airplane performance. An array of equipment, sensors and monitoring devices throughout the cabin allows the onboard team to document and evaluate the airplane's response to test conditions in real time.

The 777X test plan lays out a comprehensive series of tests and conditions on the ground and in the air to demonstrate the safety and reliability of the design. To date, crews have flown the first airplane nearly 100 hours at a variety of flap settings, speeds, altitudes and system settings as part of the initial evaluation of the flight envelope. With initial airworthiness now demonstrated, the team can safely add personnel to monitor testing onboard instead of relying solely on a ground-based telemetry station, unlocking testing at greater distances.

General Electric's GE9X jet engine wins certification from U.S. regulator

(Reuters) - General Electric Co GE.N said on Monday its GE9X engine for Boeing Co's BA.N 777X passenger jet has been certified by the U.S. aviation safety regulator, clearing a hurdle in the planemaker's path to bring its new jet to the market.

GE found unexpected wear in a part for the GE9X engine last year, forcing it to redesign the part and causing several months of delays for Boeing, which has also been struggling with the grounding of its 737 MAX planes following two deadly accidents.(reut.rs/3icoGl5)

The coronavirus crisis compounded that hold up this year as demand for air travel plunged, with Boeing saying in July it was delaying the 777X’s entry to service by a year to 2022.

GE said on Monday it has received orders and commitments for more than 600 GE9X engines, and has delivered eight GE9X test engines and two test spares for Boeing’s four 777X test aircraft.

Boeing’s 777X takes step closer to service after engine certification

So far 10 GE9X engines have been delivered for Boeing’s four 777X flight test aircraft

While Boeing’s 777X is a long way off entering service following a series of delays, its massive GE9X engines have now been certified by the Federal Aviation Administration (FAA).

“There is no substitute that can achieve the combination of size, power and fuel efficiency of the GE9X,” said John Slattery, president and CEO of GE Aviation.

The FAR (Federal Aviation Regulation) Part 33 certification involved eight test engines and saw the powerplants complete just under 5,000 hours and 8,000 cycles for.

The GE9X engine is designed to achieve 10 percent lower specific fuel consumption (SFC) compared to the GE90-115B and five percent better SFC than any other engine in its class.

The 777X had been due to enter service in 2021 with Emirates as the jet’s launch customer. Following several setbacks in the jet’s development however, Emirates revealed at the 2019 Dubai Airshow that it had decided to swap tens of 777Xs for Boeing’s 787 wide-body.

While it is thought that the jet could be delayed by up to a year, Emirates president Sir Tim Clark said earlier this year that he was confident in the certification process.

Karl Sheldon, GE9X programme general manager, said that the engine has been through “a rigorous and thorough certification and testing process”.

GE and Boeing are currently working to complete the 777X flight test programme and entry into service. Several GE9X production engines have been assembled, and GE Aviation is in the process of completing factory acceptance tests.

GE has so far received orders and commitments for more than 600 GE9X engines.
