CJ2
When Cessna redesigned their popular CJ1 private jet, known for
its low operating costs and high performance, the result was the
CJ2: bigger, faster, and better. The cabin stretched an additional
thirty three inches, the wingspan stretched an additional thirty
five. Its cruise speed outdoes the CJ by four hundred knots with
a significantly reduced fuel burn.
The design goals of the Citation Jet series can be summed up in
three words: simplicity, economy, and performance. This proved to
be a challenge, especially in creating an aerodynamic structure
that is cheap to produce and handles well. Previous Citations had
used a straight wing, which slows the aircraft considerably but
dramatically reduces production and design costs. The Citation Jet
upgraded to a natural laminar flow wing, which took four years to
design in a joint venture between Cessna and NASA. This wing delays
the onset of flow separation longer, which improves the lift-to-drag
characteristics ten to fifteen percent when compared to earlier
straight-wing designs.
The CJ2 is quite fuel-efficient, with an average fuel burn of 140
gallons per hour. The economy of its fuel burn can be largely attributed
to Cessna’s choice of engines. It uses two Williams/Rolls-Royce
FJ44-2C turbofan engines, each of which delivers 2,400 lbs of thrust
on takeoff (400 lbs more than the CJ1 and CJ1+).
The CJ2 can take off in 3,420 feet at sea level, or in 5,080 feet
on a runway at an altitude of 5,000 feet . It takes seventeen minutes
to climb to 37,000 feet. At its maximum certified flight ceiling
of 45,000 feet it reaches its long range cruise speed of 352 knots.
Its high speed cruise is 407 knots. All of the cabin’s pressurization
systems (certified to 8.9 psi) are controlled digitally, able to
maintain a sea-level cabin pressure at 23,586 feet.
The CJ1 is extremely easy to fly and can be single-pilot operated.
The Citation line was designed for forward-thinking businessmen
that would fly their own private jets to and from business meetings,
resulting in several automated systems and a simple avionics system.
For those that don’t plan to fly their own jet, its ability
to be flown by a single pilot offers greater flexibility in flight
operations and reduced per-hour flight costs.
The CJ2 has a significantly increased payload capacity in comparison
to the CJ1. Its maximum take-off weight was increased by 1,700 pounds
and the maximum fuel weight rose by 780 pounds. These alterations
result in better maximum range/payload flexibility, offering owners
more options in flight planning. The most surprising result of the
significant increase in payload is that, despite the additional
weight, the CJ2 is 30 knots faster than the CJ1 and has a range
of 1,700 miles (1,480 nautical miles) further while carrying four
passengers, 440 miles further than the CJ1.
The cabin typically holds six passengers and has a total volume
of 248 cubic feet. Its three baggage compartments can carry a total
of 1,100 pounds of luggage, all but 100 of which can be stored outside
the cabin for a less cramped cabin. The cabin is 50 cubic feet larger
than the cabin of the CJ1, allowing for one seat more than the CJ1.
The seats are typically laid out in a club arrangement with two
forward-facing seats.
The CJ2 maintains the tradition of the private jet Citation line:
economy, simplicity, and performance. Its operating costs are just
as low as the original Citation Jet, but it offers a lot more range
and a faster cruise speed. Examples of possible nonstop trips include
Washington, DC to Denver or Seattle to Oklahoma City.
CJ2+
The CJ2+ is the fifth generation of the popular Citation Jet series,
a class of private jets designed to be economical and high-performing.
They aren’t the most luxurious private jets available, but
they may be the most popular. Business travelers like the idea of
a private jet that performs economically without sacrificing performance
or reliability. These low-cost, reliable jets are possible only
because of Cessna’s insistence on simplicity of design. The
jets of the Citation series bypass many of the complexities of their
competitors, and increase performance and economy by using some
of the most economic engines available. The CJ2 was arguably the
most popular member of the Citation series, and the CJ2+ is the
new, improved version, offering lower fuel burn, longer range, and
a larger cabin.
The design goals of the Citation Jet series can be summed up in
three words: simplicity, economy, and performance. This proved to
be a challenge, especially in creating an aerodynamic structure

FJ44-3A-24 turbofan engines, each of which delivers 2,400 lbs of
thrust on takeoff (400 lbs more than the CJ1 and CJ1+).
Another of the CJ2+’s strong points also contributes to its
low operating cost: the simplicity (but reliability) of its flight
systems. It installed the fully integrated Pro Line 21 avionics
suite into the cockpit, which has been redesigned and upgraded as
well. The CJ2+ is very easy to fly when compared to similar private
jets. The benefit of having such simple operation requirements is
that this private jet can generally be operated by a single pilot,
which provides excellent flexibility in flight operations.

passengers, 440 miles further than the CJ1.
The cabin of the CJ2+ is almost identical to the cabin of the CJ2.
Seats are available for six passengers, which can track into the
aisle and away from the sidewalls for greater comfort. Folding side
tables are available for all seats and can be stored in the side
walls. All seats are equipped with a 110-volt power supply and a
fax/data port for increased productivity in flight. The CJ2+ was
redesigned with extra soundproofing for a quieter flight. An emergency
exit is located over the right wing and the twenty two cubic foot
emergency oxygen system comes standard. The three baggage compartments
can carry a total of 1,100 pounds of luggage, all but 100 of which
can be stored outside the cabin for increased passenger comfort.
