Gulfstream G650
Receives Provisional Type Certificate By Jim Douglas |
||||
November 21, 2011 - Gulfstream G650 received its
provisional type certificate (PTC) from the Federal
Aviation Administration. This clears the way for the
company to begin interior completions of the
ultra-large-cabin, ultra-long-range business jet in
preparation for customer deliveries in the second
quarter of 2012, as originally planned.
The Gulfstream G650 is a twin-engine business jet
aircraft under development by Gulfstream Aerospace.
Gulfstream began the G650 program in 2005 and revealed
it to the public in 2008. The G650 is the company's
largest and fastest business jet with a top speed of
Mach 0.925.
"We are pursuing a two-step certification approach to
keep us on track for our planned deliveries in the
second quarter of 2012," said Larry Flynn, president,
Gulfstream. "With the PTC in hand, our plan is to move
production aircraft into final phase manufacturing to
ensure customer deliveries in the second quarter of
2012."
PTCs have been common in general aviation programs over
the past 15 years. Both the Gulfstream V and the
Gulfstream G550 were issued PTCs before receiving full
certification. The four G650 aircraft in the flight-test
program have flown more than 2,225 hours during more
than 675 flights.

One of
those aircraft has a fully outfitted interior, allowing the
company to confirm weight projections and test new features,
including its Cabin Essential? design for redundant cabin
systems. Seven production aircraft have flown in preparation for
their induction into final phase manufacturing. More than 20
aircraft are in various stages of initial or final phase
production.
Among its
achievements, the G650 has flown for more than 14 consecutive
hours, with flight test data confirming its ability to achieve
7,000 nm (12,964 km) at Mach 0.85. The aircraft has also
demonstrated 5,000 nm (9,260 km) at Mach 0.90. With a top speed
of Mach 0.925, the G650 is the world's fastest civilian jet.
"The G650
will exceed the capabilities of anything on the market, flying
faster and farther, with industry-leading fuel efficiency and
reduced emissions," Flynn said. The aircraft controls will be
completely fly-by-wire, with no mechanical control between pilot
and flight surfaces.
The
surfaces will be moved by a dual hydraulic system. More
airliners today are using fly-by-wire, but only one current
business jet (the Falcon 7X) is so equipped. The G650 will share
yoke and column with the G550 in an effort to receive a common
type rating. |
