More about Cessna Citation CJ4 for sale
Cessna Citation CJ4 is continuation of the range Citation Jet. The first flight has taken place on May 5, 2008. When Cessna Aircraft has published results of flight tests of Cessna Citation CJ4, these digits have caused noticeable revival as on base, in Wichita, and on the neighboring continent, in Brazil. In comparison with design calculations the business jet worth 8,75 million dollars has turned out easier, more powerfully and quicker. Range and runway characteristics have surpassed expectations.
In the light of similar results there is a temptation to neglect the become already banal comparison with Embraer Phenom 300 which is considered to be the direct competitor of Cessna Citation CJ4, and instead to arrange a duel between Cessna Citation CJ4 and Learjet 45XR. Really, if both of these airplanes take aboard five passengers and at the same time start from San Diego, say, to the Savanna, then 45XR will be ahead of the rival for only seven minutes.
The main difference between them consists that Citation will be able to take off immediately in the opposite direction with the same passengers against a head wind for 40 nodes (if gets permission to occupy an echelon 450). And here the crew of Learjet should reserve time for refueling or technical landing. Fierce competition between Cessna and Learjet – not news. It has begun in 1988 when Cessna has removed to the public CE 560 Citation V.
This airplane gathers the maximum (true) cruiser speed to 427 nodes that is only 20 nodes less, than at the range Learjet of the 30th series. But at Citation V two advantages and before short-range Learjet 31A, and before his “long-range” fellow 35A: the best runway characteristics and more spacious salon. Moreover, it has an external luggage compartment which so is not enough for owners of Learjet. Learjet trumps: higher cruiser speed (actually on 50 nodes on average) and bo’lshaya range (in case of 35A). However, Learjet have restrictions on the maximum take-off weight at take-off in hot weather from a number of the small airfields located highly above sea level. For Citation V these conditions not a problem.
The subsequent Citation models of a series 560 – Ultra, Encore and Encore + – and their rivals from Learjet 40/45 family have added fuel to the fire of the hot competition between two producers. Cessna traditionally shows shorter running start and run. Learjet takes the speed, range and useful loading at full tanks. However Cessna Citation CJ4 does the breakthrough forward which is almost leveling a historical distance between two brands. Yes, on runs from 550 to 1800 km Learjet 45XR will come the first, having saved passengers about five minutes. But at Cessna Citation CJ4 range with five passengers is onboard nearly 470 km more, and at long ranges it and on time will practically not concede to the rival.
The main lack of Cessna Citation CJ4 – lateral section of a fuselage. Designers of Cessna have borrowed a plain round fuselage in section from vintage FanJet 500 of a sample of the end of the 60th. Of course, in comparison with the first generation of Learjet the inside of this airplane was considered as spacious. But also Embraer, and Learjet, two main competitors of Cessna in this market niche, in the latest models have replaced a paradigm, having developed from scratch the fuselages offering to passengers it is more than space at the level of the head, shoulders and elbows, than series 500 Citation, including CJ.
On Cessna Citation CJ4 attempt a little to increase the area of a floor in the central section of salon by means of use of external frames is made. This decision has allowed to add 2 inches to floor width in comparison with the previous CJ models, but it was not succeeded to approach the volume of Phenom 300, Learjet 40XR or Learjet 45XR salons. If to understand, the competition between Cessna Citation CJ4, Phenom 300 and the Learjet airplanes of the 40th series more rigid, than can seem at first sight. The matter is that Cessna Citation CJ4 has evolved dramatically forward in comparison with CJ3 thanks to a number of new processing methods in a design of a glider and onboard systems. By words Norma of Baker, the head of the Cessna Citation CJ4 program, to 90% of the design decisions realized by the airplane are innovative.
These changes can change alignment of forces in a niche of easy jets. As well as in case of Phenom 300 and Learjet of the 40th series, the wing of Cessna Citation CJ4 is developed from a blank sheet, with use of the latest computer technologies. By and large, it proportional the reduced copy of a wing of Citation 680 Sovereign, with the little changes of contours of an edge improving aerodynamic characteristics when flying at small speeds. They have allowed the airplane to beat initial design calculations of runway characteristics. Better – only at Citation Mustang and Embraer Phenom 100 and that with a scarcely noticeable separation. Cessna Citation CJ4 – the first narrow-body Cessna with an arrow wing (12,5 degrees on a quarter of a chord). Wing area – 30,7 sq.m. Aerodynamic characteristics when flying at high speeds not less impressively.
The maximum operational speed has been increased to 0,77M that almost does not lose in comparison with 0,78M at Phenom 300 and 0,81M at Learjet. But for routine operation more valuably the fact that the speed at which the aerodynamic resistance of a wing begins to grow exponential owing to emergence of jumps of consolidation is significantly above the most admissible and it provides effective operation at high cruiser speeds. It should be noted that all indicators of range with the maximum cruiser speed (including 3700 km with a reserve fuel reserve) are given by the producer at the rate of presence of five passengers and two crew members onboard. Reduction of speed increases range slightly more, than by 8%. The tee tail plumage is borrowed CJ3. Its keel has the extended chord for improvement of traveling controllability, and the size of the stabilizer is increased for improvement of longitudinal stability that has important practical value, considering high cruiser speeds of Cessna Citation CJ4. Assembly of a fuselage is carried out “outside inside”, that is at first the covering which keeps by means of vacuum building berths gathers. It guarantees faultless streamlining of the case.
Then the framework and “stuffing” is inside inserted. Cessna actively uses constructional glue for connection of different elements, and for the last more than three decades of production the company has achieved in it big skill. In addition to a clear advantage – decrease in aerodynamic resistance, one of pluses of such technology – reduction of time of production. However in comparison with mechanical fixture glued joints can weight the airplane considerably. In case of Cessna Citation CJ4 this risk remained purely theoretical: eventually the airplane was 8 kg lighter, than designers assumed.
The weight of the empty equipped airplane (including two pilots) makes 10242 pounds (4646 kg). The airplane nose has undergone essential alteration. In particular, its profile became more aerodynamic, it has also received the conic strengthened front glazing. In comparison with predecessors of the CJ series at Cessna Citation CJ4 the most advanced systems. So, for example, changes, the concerned electricians, really impress.
For narrow-body airplanes of family the level of duplication is unprecedented: all aircraft radio-electronic equipment, including an auto pilot, has quadruple reservation. And even in an improbable case of failure of all four power supplies of power of the main accumulator will be enough for the minimum providing the airplane with the electric power which is required for completion of flight. As for rivals, Phenom 300 and Learjet of the 40th series, they lose in the matter: at both only on two power supplies. The accumulator at Cessna Citation CJ4 – lithium – ion. It is joint development of Cessna and A123 Systems, the first accumulator of this kind used on a business jet. In comparison with standard (for example, nickel – cadmium) it not only better works, but also saves more than 13 kg of weight of the airplane. Similar accumulators are installed now also by Gulfstream on the latest models. And Embraer and Learjet use lead-acid or nickel – cadmium options.
Thanks to alternative approach in this question engines on Cessna Citation CJ4 can be started from the accumulator at temperatures up to -40 °C. Systems of sealing are similar at all three airplanes. On Cessna Citation CJ4 system of sealing (0,61 atm) supports onboard pressure at the level of height of 2380 m when flying on FL 450 echelon. On the same echelon onboard Phenom 300 (0,63 atm) passengers will feel, as at the height of 2011 m, onboard Learjet (0,64 atm) – as on 1960 m as the possibility of flight up to FL 510 echelon is provided. And Cessna Citation CJ4 and Phenom 300 are equipped with the standard evaporating air conditioning system: before start of engines air in salon is cooled by means of a land-based source of a power supply. For Learjet such system is provided as an option.
The difference is that Learjet 45XR have AFU, Honeywell RE100 which competitors do not have. AFU heating and conditioning of salon ensures autonomous functioning of the airplane on the earth, including avionics, electric devices in salon. As it was already told, the volume of Cessna Citation CJ4 salon is less, than at Phenom 300 or Learjet of the 40th series, but it only one of several measurements of level of comfort of passengers. In a back compartment (which, by the way, is 10 cm longer, than analog in Phenom 300 salon, – and it means that each passenger will get on a two-three of centimeters more personal space) the club section from four chairs plus two chairs by the person in the direction of flight is located.
A floor in pass is drowned both on Cessna Citation CJ4, and on Phenom 300 for the purpose of an altitude gain of salon. In standard configuration opposite to an entrance door there is the seventh passenger seat. It and the cabinet located on the right can be offered in favor of a two-seat sofa; replacement is made free of charge and will save 11 kg of “empty” weight. At the disposal of the ninth passenger a flap seat over a toilet bowl in a toilet. Certainly, three occasional seats are not so convenient as the main six. Paul Learjet 45XR is equal, without deepening therefore width of salon is used more rationally. The main compartment 5 m long allows to place one more seat row. Thus, in Learjet 45XR salon with comfort eight passengers will be located. It would seem, length of salon of all on half-meter is more, than in Cessna Citation CJ4, means to “excess” passengers will be rather small. However thanks to the fact that the front partition and an entrance to salon are removed closer to a pilotsky cabin, than in Cessna Citation CJ4 or Phenom 300, enough room is made for legs of the seventh and eighth passengers.
Though the Cessna Citation CJ4 salon more than on half-meter is longer, than at the predecessor, CJ3, illuminators in it is three less: only five on the right board and six on left. At Learjet 40 of illuminators 14, at Learjet 45 – 16, therefore the level of natural insolation of salon sufficient. At Phenom 300 four windows on the right and five at the left plus two more in a toilet, and they surpass in the size also Cessna Citation CJ4 and Learjet. As for artificial lighting, by all three airplanes it is carried out by means of long-lasting LEDs. Air temperature is controlled separately in two compartments of salon. Both of them are equipped with folding tables, and the bars located in front part of salon – containers for hot and cold drinks and ice, and also tanks for storage of provisions. Entrance door of Cessna Citation CJ4 – iteration of the early Citation models of the 500th series: it moves forward outside sideways, its sizes are increased to 61 x 122 cm and it is supplied with a folding ladder.
On noise level in Cessna Citation CJ4 salon I have inherited achievements of the previous model, CJ3. Impressive results were achieved also by designers of Learjet. And here engineers of Embraer should work that in this question Phenom 300 it could be compared to competitors, judging by the fact that his younger fellow, Phenom 100, has turned out quite noisy. As a control system of parameters of salon (lighting, shutters of illuminators, systems of entertainments) new development of Rockwell Collins – Venue CMS is established. Cessna declares that this equipment is for the first time installed onboard a business jet. The opportunities earlier inherent to jets of heavier category, such, for example, as the separate temperature controller for salon or a blind with the electric drive, have reached also an easy class now. In creation of architecture of the CMS system developers have applied the principles borrowed from the organization of avionics. On the practical level it means that CMS has turned out simpler and reliable, than all previous generations.
The system uses the distributed control of the controllers located in each chair. Components are united in the Ethernet network with ring architecture therefore in case of failure of one of them another will undertake its functions. Venue CMS is supplied with the extensive abilities of self-diagnostics simplifying process of search and debugging. CMS turns on three 10,6-inch monitors with high resolution (HD), the satellite radio receiver, satellite telecommunication on the basis of Aircell Axxess II Iridium, and also numerous ports and slots, including for a MP3 players, and two electrosockets for 110 Century. The moving card with a flight trajectory (Airshow) is included into standard providing.
The interior options offered Cessna include a variety of finishing materials, the rotating chairs, iPod-stations and numerous aprgreyda of system of entertainments. It is a little about external luggage compartments. At Cessna Citation CJ4 and Phenom 300 they are almost identical on an arrangement and volume: one “luggage carrier” (at Embraer of 1,9 m3, at CJ4 – 1,6 m3) in a tailpiece of a fuselage and a small compartment in nasal part (0,14 and 0,42 m3 respectively). The airplane which has got to us for test flight – the prototype with serial number of N525NG loaded by the test equipment instead of a standard interior. So its empty weight more than on 300 kg exceeds the weight of serial copies. From 2,65 t of fuel onboard and two crew members, without passengers, take-off weight makes 7620 kg. The Pilotsky cabin of Cessna Citation CJ4 is created by designers of Cessna that is called from a blank sheet. And it is noticeable at once: it is much more ergonomic, than all previous models of CJ family. The most often used devices and switches are located approximately at the level of eyes.
The most part of switches of onboard systems is taken out on the inclined panel under displays, now it is possible to reach switches and toggle-switches. What is used infrequently, for example the control of trimmers or inclusion of external headlights, is on the central console. LEDs of indicators provide unambiguous perception of a condition (on/off) of the relevant systems. Cessna has replaced tens of independent sensors with indication on the multipurpose display (MFD). However designers have refused a graphic way of display of the engines and systems given about work in the form of survey charts: information is still issued in the form of digits, arrows and indexes. About any emergency situations the crew will be reported by system of preventions. We turn on both engines and we taxi on take-off from the runway 1R of factory airfield of Cessna in Wichita.
Abrupt turns on taxiing make strong impression. If to clamp a brake, to apply differential draft and to be unrolled on internal wheels of the main racks, the radius of a turn will not exceed 10 m. Having got permission to take-off, we align the airplane to the center of a strip and we remove ORES to the third mark. At draft almost in 3,3 t at the airplane almost sports thrust-weight ratio with coefficient 2,32:1. We disperse very quickly. Efforts at a separation small. We assume airs almost by 20 degrees to keep instrument airspeed at the level of 200 nodes according to rules of flights in air space of a class D. The Poslushnost of the airplane is obvious from first minutes of flight and really impresses. Flight “on hands” is carried out easily and easy, with observance of all requirements for smoothness of the movement and accuracy of navigation. The moment of engines is almost imperceptible. Wichita Approach and Kansas-City-Centre allow free ascent to FL 450 echelon.
From the moment of a separation before achievement of a cruiser echelon there pass 23 min. (at the mode of a set 240 KIAS/M0,64 and conditions of the atmosphere is slightly warmer, than ISA). It is nearly 4 min. faster, than it is specified in flight plan in spite of the fact that after FL 300 the set was less effective as the control system of flight tried to keep the recommended M0,64 set speed with a margin error of 1-2%. Having turned into horizontal flight, we accelerate to 414 nodes. The fuel usage indicator (airplane weight now 7300 kg) was stabilized and makes 1020 pounds (463 kg) an hour – slightly higher, than is declared by the producer. We make a turn by 180 degrees against wind and we head back for Wichita. A roll we put severe. Buffeting began to be felt only after 52 degrees when the overload has passed for 1,8g. We decrease to FL 310 for check of functioning of air brakes. On the maximum value of release the airplane assumes airs a little, but despite considerable resistance, shaking is almost not felt. Under atmospheric conditions of ISA of -3 °C at this height maximum speed is limited to 453 nodes.
Fuel usage at these indicators makes 1800 pounds (816 kg) an hour. At the height of 16000 feet we make several 45-degree turns at a speed of 250 nodes and we are convinced that the airplane shows excellent controllability: even without use of the trimmer we are not beyond six nodes on speeds and 40 feet on height. We need to check behavior of the airplane at drop. By the way, according to Cessna policy, all types of drop are carried out only before activation of the automatic machine of shaking of a steering wheel. When flying on a clean wing it occurs at an instrument speed of 113 nodes, at reduction of speed to 103 nodes buffeting and easy rocking is observed by wings. We add gas and we lower a nose by 5 degrees.
A conclusion comes from drop not instantly, but the airplane keeps full controllability and the maximum loss of height does not exceed 140 feet. At the released chassis and flaps the vibrator works at a speed of 98 nodes (on devices), at a speed of 83 nodes begins to shake. We lower a nose, we release flaps by 15 degrees and in process of a set of speed and height we remove in horizontal flight. We “have dropped” by 300 feet. For the pilot who was earlier not sitting in a cabin of Cessna Citation CJ4, drop exercises are a valuable lesson. If to begin a conclusion from drop at the first symptom – shaking of a steering wheel, the required effect will not keep itself waiting. Between the moment of activation of the vibrator and emergence of buffeting – the generous delta of values of an angle of attack. And even at great values the airplane keeps controllability. It is time to come in the land. More precisely, we will execute several calling, for a start on ILS and GPS. Reference speed of a contact (weighing 6940 kg) – 112 nodes. Release of flaps in the provision of 15 degrees at a speed near the 200th catch causes soaring up. Reaction of engines to change of the mode during calling is amazingly proportional that it is possible to tell also about the trimmer. In general efforts it was necessary to apply very little, and the airplane behaved steadily.
Similar to all models of CJ family, at Cessna Citation CJ4 that is called the raised volatility as a result of big wing area. Over a strip it leads to strong screen effect. Even – and you for a long time soar small overspeeding when landing over the earth. So we recommend to meet a strip end face at a speed of a contact and to quickly clean gas. During take off and landing with imitation of failure of one engine with surprise it is noted with what ease it is possible to parry the developing moment pedals. Effective work of a yaw rudder does similar maneuvers by a simple task – perhaps, even simpler, than by other airplanes of this family glorified by the complaisance. We make the completing landing on the maximum values. Brakes with a digital control work faultlessly together with very effective interceptors. Run is equal to about 760 m, without any feeble efforts from the center of a strip aside. Conclusions. Cessna Citation CJ4, obviously, the best representative in family of the narrow-body Citation constructed until now. In controllability parameter to it is not present equal among schoolmates.
The reorganized pilotsky cabin significantly reduces an operational load of crew. Flight technical characteristics correspond or surpass the indicators declared by the producer. Comparative analysis of B&CA shows that Cessna Citation CJ4 – structurally effective, universal airplane which managed to overcome many hereditary “diseases” of a series 525. It is capable to transport five passengers with two crew members at full tanks. Take all eight places – or even nine if the sofa is established two-seat, – and all of you will be able equally to connect any couple of the cities in the USA, having planned one technical landing. By the way, Cessna, as well as Learjet, gives all calculations for scales taking into account dvukhchlenny crew whereas Embraer, specifying values of range, speed etc. for Phenom 300, calculates that in a cabin there will be one pilot. One more competitive advantage of CJ4 – excellent, the best in a class of easy jets runway characteristics.
Rummage in flight technical documentation on Cessna Citation CJ4, and you will find that this airplane is designed for flights on the same echelons, as Learjet. The combination of rather big wing and reliable high-rise characteristics of Williams FJ44-4A engines allows direct dialing to FL 410 echelon above on all routes range more than 370 km. Really, to get on FL 450 straight with the runway is an only way to squeeze out the maximum range of 3708 km advertized by the producer with the maximum cruiser speed and to sit down with a fuel reserve on 185 km according to requirements of NBAA IFR. In principle, on short routes commercial speeds can be above if to go down below the 400th echelon, but fuel usage in that case will sharply increase. We will count. When flying on maximum speed 453 nodes on FL 310 echelon the airplane eats 830 kg (1828 pounds) of fuel an hour, and, thus, one pound is enough for overcoming of distance in 0,459 km. It is the most uneconomical indicator in a class of easy jets. But on FL 450 echelon speed decreases to 430 nodes, and fuel usage – to 444 kg (978 pounds) an hour, and the required ratio makes already 0,81 km for fuel pound, and it is 10% better, than the poor eater of Learjet 45 which manages at the same speed and height to overcome 0,74 km on one pound of kerosene.
The possibility of operation in the majority of airfields of aircraft of general purpose, even belongs to unconditional advantages where length of a strip is insufficient for some other models, especially in the conditions of highlands or high temperatures. Ergonomics of a pilotsky cabin – one more explicit plus allowing to carry CJ4 to the best in the class on avionics. By the way, it is the only easy jet equipped with a new meteoradar of Multi-Scan from Rockwell Collins. This device creates three-dimensional images of hundreds of cubic kilometers of air space before airplane for the purpose of identification of possible adverse meteoconditions. Similar systems are installed only on business jets of much higher price category. Same treats also a control system of parameters of Rockwell Collins Venue CMS salon.
One of bargaining chips of Cessna is a world level of support of operators. Any other producer of easy business jets has not earned so high rating. Undoubtedly, Cessna Citation CJ4 – the most capable of all family of narrow-body Citation. It surpasses Encore+ in all indicators, and costs nearly 400 thousand dollars less. Rather strong competition to this airplane would be made by Hawker 450 equipped with avionics of the last generation and PW535 engines – if the program has not fallen the victim of reduction of production costs. Meanwhile, judging by results of tests, Cessna Citation CJ4 is ahead of the main rival, Phenom 300, on the majority of LTH. However, it is worth waiting for final digits and from Embraer to judge a separation. Though some of direct competitors of Cessna Citation CJ4 can brag of more spacious salons, Cessna offers a hardly debatable combination of satisfactory comfort for passengers, good LTH, innovative technologies and excellent service. It allows to conclude that Cessna Citation CJ4 has created for itself a special market niche which will provide it good marketability. However Cessna, as well as rival fellow countrymen from Wichita – Hawker Beechcraft and Bombardier Learjet, is forced to look back at Embraer constantly now.
