Boeing: 'The airplane, identified as VQ001, taxied then lifted off the runway at 12:10 p.m.' (12:10 PDT = 19:10 UTC); FlightGlobal[5] reports the 5h 5min flight began at Everett and ended at Boeing Field.Boeing 767-400ER Makes Its First Flight at Everett
The first Boeing 767-400ER, VQ001, lifted off from Paine Field at 12:10 p.m. on 9 October 1999 for a five-hour test flight to Boeing Field. The longest 767 had been launched in April 1997 with a 21-aircraft Delta order.
- Boeing 767 chief pilot Buzz Nelson and first officer John Cashman, the flight-crew-operations director, flew VQ001 from Paine Field west down the Strait of Juan de Fuca, landing at Boeing Field after 5 hours 5 minutes[1][5]
- Program manager Pat Shanahan called it "as good as it gets"; Boeing planned a six-and-a-half-month, roughly 800-flight-hour test campaign for three aircraft, but the program ended up at 1,150 flight hours after a 40-day strike and a roll-off fix[1][3]
- The 767-400ER was launched in April 1997 with a 21-aircraft order from Delta (orders totalled 54 by first flight) and rolled out in August 1999[1]
- FAA certification and 180-minute ETOPS followed on 20 July 2000, and Boeing said testing showed the jet burned less fuel and needed less runway than first expected[2][3]
- Flight International's pilot found it "stable, with good natural damping" and noted vortillons had been fitted after certification flying found the "dirty" stall marginal[4]
Notable features
- 767-400ER: length 201 ft 4 in (61.37 m), wingspan 170 ft 4 in (51.92 m) with raked wingtips, MTOW 450,000 lb (204.1 t)[1]
- Seats 245 in three classes or 304 in two classes (Boeing's airport-planning layout shows 296), up to 15 percent more than the 767-300ER; 777-style flight deck[1][4]
- Range about 5,625 nmi (10,415 km); General Electric CF6-80C2B8F engines of 60,600 lbf; takeoff field length about 10,300 ft at maximum weight, sea level, standard day (read from graph)[1]
