APRIL 2011 AUSTRALIAN AVIATION
the aircraft is set to ll and assess just how
successfully it achieves it.
MORE THAN A GLANCE
As the Citation CJ4 sits proudly on
the ightline at Avalon, its form speaks
volumes for the aeroplane. Immediately
apparent is the comfortable rounded
nose that is so distinctive of the early
CJs. However, atop the nose sits a newer,
sleeker, wrap-around windscreen and side
windows of electrically heated glass. e
wing is swept at around 12 degrees and is
reminiscent of its larger sibling, the Sov-
ereign, suggesting a higher cruising speed
than the CJ3. Although the CJ4's wing
span is slightly less, its fuselage is slightly
longer than the CJ3's and overall gives
a very balanced appearance. So at rst
glance, the CJ4 suggests a higher cruising
speed with additional cabin room for the
passengers and crew than its forerunner.
Continuing to walk around the twin jet,
more features become readily apparent. e
T-tail and aft-mounted turbofan engines
possess a distinctively 'Cessna look'. Each
engine is capable of producing 3621lb of
thrust with their intakes heated by bleed
air, while the tailplane retains the tradition-
al Cessna pneumatic de-icing boots.
Accessibility to the various systems
during the pre ight inspection is straight-
for ward. Oxygen and gear 'blown down'
gauges are in the nose locker, single point
refuelling is ahead of the wing on the
starboard side, while the hydraulic system
is accessed to the rear. Notably, the CJ4
possesses a constant 3000 psi system not
featured on earlier models, and unless
a top up of oil is needed, levels can be
checked without the use of a ladder. On
the port side, two access doors reveal
the battery and brake system aft of the
wing. e new 44 amp-hour lithium ion
battery o ers a 14kg weight saving over
an equivalent NiCad unit, while the new
positioning of the brake system from the
nose section reduces the distance from the
unit to the brakes.
In all aspects, the location of these vari-
ous systems are well thought out, but even
more signi cant are the clean spaces within
the nose and aft baggage lockers by virtue
of this. In fact there is an impressive 2.15m3
of storage room.
Overall, the CJ4's exterior is all Cessna.
It is clean and functional, but possibly
more so than the other aircraft in the 'CJ'
line-up. With increased baggage space,
well thought-out systems access and a
wing that suggests a slippery cruise speed,
the balance of appearance and functional-
ity seemed just right.
Now it was time to climb aboard and see
if beauty was more than skin deep.
BENEATH THE SURFACE
Simply boarding the CJ4 revealed a new
perspective. e door did not possess a
window like the CJ3, but nor did it taper
in its dimensions towards its top. Rimmed
with a passive seal, the door is symmetrical
and generous in its dimensions for ease of
access. Once onboard, the luxurious interior
was just as one would expect for an aircraft
of this category and calibre. In addition to
a slightly longer cabin, the oor has been
lowered compared to the CJ3's, reducing
the degree to which the curved upper walls
impinge on headroom along the cabin's side.
Furthermore, the CJ4 o ers a fully integrat-
ed cabin management and entertainment
suite with the ability to access CDs, Blu-Ray
DVDs, games, 3-D moving maps and so on.
e options seemed limitless, but I was keen
to move forward and see the technology
available in the cockpit.
On sliding into the left hand seat, I
was immediately impressed by the CJ4's
cockpit. It is superbly clean and ergonomic,
dominated by the Collins ProLine 21
suite's four 20 x 25cm screens. Signi cantly,
this is one screen more than the CJ3,
permitting adequate displays of ight and
navigational information, with a screen still
available to call up the relevant Jeppesen
chart. e entire panel is so e cient with
most systems accessible on the lower
inclined panel, while the autopilot and fre-
quently used switches are near eye height.
e two FMCDUs are centrally located
ahead of the light switches and thrust
levers, while the trim controls and engine
start switches are aft of the levers.
e thrust levers themselves are sporty yet
substantial, with the 'Go-Around' buttons
located on the outboard faces. Di ering
from earlier CJ aircraft, the CJ4 thrust levers
possess detents for cruise, climb and takeo .
ere is no reverse thrust on this aeroplane,
but at either side of the thrust levers are
located a speed brake lever and ap lever.
Everything is clear, logical and close at hand,
CLEAN AND ERGONOMIC The CJ4 flightdeck is dominated by the Collins ProLine 21 suite's four 20 x
25cm screens. (Cessna)
SEVEN SEATER The CJ4 cabin features a six-place centre club seating arrangement, with a seventh seat
across from the entry door. (Cessna)
