be used as a classic flap for increased
lift or an aileron for roll control and has
been designed to improve handling
during approach, especially on steep
descents, increasing drag while
maintaining a high-lift coefficient.
Because the PW812D is significantly
heavier than the Silvercrest, Dassault
has inserted a 20in (51cm) plug in
the fuselage, forward of the wings, to
balance the weight gain.

On Board
The increased fuselage length
provides the additional benefit of
increasing the available space inside.
It has the largest cabin cross section
of any purpose-built business jet,
measuring 78in (1.98m) tall and 86in
(2.18m) wide. For comparison, the
Gulfstream G650 measures 77in
(1.85m) tall and 84in (2.13m) wide.
“The industry has been moving
towards ever wider and higher interi-
ors, and customers told us what they
wanted most in our new Falcons was
more space,” continued Trappier.
“So, we designed the Falcon 6X from
the cabin out, making it as passenger-
centric as we could while still
delivering the high performance and
other flying qualities that customers
value in Falcons.”
It can accommodate up to 16
passengers and be split into three
distinct zones. Customers can choose
from multiple configurations including
a large entry way/crew rest area and

(D for Dassault), which
the CEO described as
the “closest match”. The
PurePower PW800 engine
family first flew in April
2013 and has amassed in
excess of 79,700
testing hours and more
than 585,000 in service
hours. The PW812D
variant is rated at 13,000-
14 ,000lbs thrust, exceed-
ing the 11,450lb of thrust
the Silvercrest could produce.
As a result, the 6X has a higher
maximum take-off weight (MTOW)
of 35,135kg (77,460lb) compared with
the 5X’s specified 31,570kg (69,600lb).
The Falcon 6X is largely based on
its predecessor’s aerodynamic and
systems features which have already
been validated during the latter’s brief
flight test programme. This includes
Dassault’s new digital flight control
system (DFCS), which controls all
moving surfaces. Trappier says the
DFCS “ensures the best handling
characteristics ever seen” and had
“behaved perfectly” during testing.
The new model retains the same
wing aerodynamic shape, which
Trappier noted “proved very efficient”
during the 5X’s flight testing. Dassault
claims the design also “minimises the
impact of turbulence”. The Falcon 6X
is the first business jet to feature a
flaperon, a high-speed deflection
control surface. Dassault says it can
