The Boeing 777-300ER completed its maiden flight,
Monday, beginning a 1,600-hour flight-test program that's expected
to bring US certification by early next year. The newest
member of the 777 airplane family, with its distinctive red, white
and blue paint scheme, took off at 10 a.m. Pacific from Paine Field
in Everett, Wash. After flying a little over three hours, it landed
at 1:02 p.m. at Seattle's Boeing Field.
Veteran Boeing pilots Capts. Frank Santoni and John Cashman were
at the controls. Santoni is the chief 777 test pilot and Cashman is
director of Flight Crew Operations and chief pilot for Boeing
"The Boeing 777 is an incredible flying machine," Santoni said.
"It's no wonder pilots call it the 'World's Greatest Airplane.'
Being at the controls of an airplane on its first flight is a rare
and unique opportunity, and it always is exciting."
The 777-300ER is the fourth 777 model. Cashman and Santoni also
took the 777-200ER and 777-300 on their maiden flights, and Cashman
was at the controls when the first 777, the 777-200, first flew on
June 12, 1994. During today's flight Santoni and Cashman took the
777-300ER to an altitude of 15,000 feet and an air speed of 0.50
Mach, or about 370 miles per hour. Typically, the 777's cruise
altitude is 35,000 feet, and its cruise speed is Mach 0.84, about
484 miles per hour.
Santoni and Cashman tested some of the airplane's systems and
structures, as on-board equipment recorded and transmitted data to
a flight-test team at Boeing Field. That data, and the crew's
comments, will be analyzed in the near future.
The flight-test program will involve the airplane flown today
and a second one that is in the final stages of assembly. Those
will be subjected to a variety of conditions to prove the safety
and reliability of the airplane's systems. Flight times will vary,
including one extended-range flight lasting up to 19 hours. More
than 1,000 hours of ground tests also are planned.
The comprehensive testing will validate the
777-300ER's reliability and service-ready condition for all
intended missions. "I'm so proud of this team and what they've
accomplished," said Lars Andersen, Boeing 777 Longer Range program
manager. "Boeing employees, airlines and a global network of
suppliers worked together to design and manufacture the 777-300ER.
We're now ready to enter into the flight-test stage of the program
with a mature and proven design."
Airframe certification by the U.S. Federal Aviation
Administration is expected during the fourth quarter of this year.
Certification of the interior is expected during the first quarter
2004. International Lease Finance Corp., and its customer Air
France, will receive the first 777-300ER in April 2004.
Touted as the world's most technologically advanced airplane,
the 777-300ER will have updated avionic, electrical, flight and
environmental control systems. GE Aircraft Engines manufactures the
engines for the 777-200LR and 777-300ER airplanes. The new engines
have been recognized as the world's most powerful commercial jet
engines and currently hold a Guinness World Record for thrust.
"This is a truly outstanding achievement for all
of those who have worked so closely together on the new 777," said
Chaker Chahrour, general manager of the GE90 engine program at GE
Aircraft Engines. "The first flight of the 777 with GE90-115B
engines signals a new beginning in aviation. With the addition of
the 777-300ER and the 777-200LR airplanes, customers will be able
to reach more non-stop global destinations providing more efficient
travel to their passengers."
There are two Longer-Range 777 models. The 777-300ER carries 365
passengers up to 7,420 nautical miles while the 777-200LR can carry
301 passengers up to 9,170 nautical miles.
Both the 777-300ER and the 777-200LR were launched in February
2002 by Boeing and GE Aircraft Engines at the request of customers
who asked for an airplane with additional flexibility to serve the
non-stop routes that passengers demand. The 777 family has captured
nearly 70 percent of the market since the airplane's October 1990
launch. Thirty-nine customers and operators worldwide have ordered
619 777s, including 61 Longer-Range 777s ordered by seven
customers: Air France, All Nippon Airways, EVA Airways, GE Capital
Aviation Services, ILFC, Japan Airlines and Pakistan International
