The 777-9 thatย Boeingย willย use to conduct extendedย operations (ETOPS)ย andย functionย and reliabilityย testing flew for the first timeย Friday, completing anย approximatelyย three-hourย profile overย Washington State,ย Idahoย and Oregon.
Capt.ย Dan Mangelย andย Capt.ย Jake Millerย completed a standard first-flight profile that tested the airplaneโs systems and structures,ย which were monitored onboard by systems operators Scott Brihn and Zachary Lewis; flight analystsย Seth Town, John Theeringer and Michael Deutsch; instrumentation specialist Lauren Meyer; and propulsion analyst Kinsey Bilyeu. The airplane landed at Paine Field in Everett, Wash., atย 5:35ย p.m. PT.ย
- โThe purpose of todayโs first flight is to test the entire airplane as a system, and then all the individual systems to make sure theyโre functioning properly,โ said Capt. Dan Mangel, Engineering pilot.ย โThe airplane performed beautifully on its first flight; it was great to fly.โย ย ย
Why it matters:ย Regulatory approval forย ETOPSย willย allow operators to fly the airplane extended distances from an airport suitable for landing, opening more direct routes that save time and fuel. Following extensive analysis, labย testsย and engine tests, as well as validation of the maintenance program,ย ETOPS testingย will includeย proving flights toย demonstrateย the 777-9 can safely and reliablyย conduct trans-oceanic routes andย support extended diversions.ย ย
Function and reliability testingย willย simulateย routineย operationsย in a variety of conditions toย demonstrateย the airplaneย canย operateย safelyย and reliablyย in service.ย
Preparing for flight:ย Teams rolled the airplane out of the Everett factory, applied a white livery, fueled the airplane, completed engineย runsย and conducted a taxi testย in the weeks and daysย before flight.ย ย
- โItโs quite a milestone, but itโs not the end of the line,โ said JeRae McCoy,ย 777X Change Incorporationย & Refurbishmentย conformities manager, who supported theย build of the airplane. โWeโveย got more work to doย to certify this airplane and begin deliveries.ย Weโreย going to keep working together to get there.โย
Continuing a legacy:ย The 777-9 will continue the 777 familyโs history of long-haul, twin-engine efficiency:ย The original 777 entered service with ETOPS approval. Its first revenue flight 31 years ago,ย between London and Washington, D.C., was an ETOPS flight.ย
Testing, certification, delivery:ย Theย 777-9ย program has logged more than 4,800 flight test hours across the 777-9 test fleet. In addition to the dedicated test airplanes, production-configuredย airplanes โ like this seventh 777-9 to fly โ are supporting certification work ahead of first delivery in 2027, the company said.ย
- โAirplane development is not easy, but it is such a worthy endeavor because we are creatingย incrediblyย capable airplanes that will safely transportย peopleย around the worldย for generations,โ said Terry Beezhold, 777-9 vice president and program manager. โA big thank you to our team for their continued hard work and to all of our 777X customers.โย ย
About the family:โฏThe 777X family โ the 777-9, the 777-8 Freighter and the 777-8 passenger airplane โ are the newest members of Boeingโs market-leading widebody family.ย Boeing teammates designedย themย to maximize efficiency and environmental performance, drawing on technologies proven on the 777 and 787 Dreamliner and new innovations, according to the company.ย
- Customers have ordered more than 650 777X airplanes.ย
