Very hard to beat planes Gulfstream G450, which are produced for the past 10 years, in terms of their reliability, payload, and cost. Prices for this business jet range from 15 to 32 mln., Depending on the age and condition of the aircraft. G450 - one of the few large aircraft to business jets capacity, designed to carry up to eight people at a distance of 7960 km at a cruising speed 0,8M (with a reserve supply of fuel to fly a distance of 370 km). Compared with models Gulftstream IV first and second generation of the G450 have a number of improvements designed to reduce aerodynamic drag, upgraded turbofan engines Rolls-Royce Tay Mk 611-8C digital automated control system (FADEC), as well as more powerful and less noisy APU.Business Jet G450 to keep the base of the fuselage Gulftstream IV with a nose section, which is taken from the glider Gulftstream V, but is distinguished by the electrical system and automatic pressure control system, a high pressure booster system aileron de-icing system of automatic control and other changes. An increase of 30.5 cm length of the bow section to provide additional space in the legs for the pilots, as well as more convenient folding chair for the third member of the crew.Gulfstream has also equipped its aircraft instrumentation complex PlaneView, the main features of which are four large LCD display and projection devices HUD c improved system of visual observation. Complex PlaneView eliminates the paper-based information schemes airfields, as well as an optional system is equipped with ADS-C for flights over oceans, the system CPDLC (ground controllers to communicate with pilots on the data transmission) and synthetic vision devices. So avionics on these business jets in no way inferior to the equipment of the latest aircraft.The main lounge, as usual, is divided into three sections. The aft cabin is a club section with four chairs, in the central part - the conference section with four chairs and a small table with two chairs, or, turn to each other in the aft - stateroom with a sofa and / or other items. In the main cabin control units are also dual-zone climate control, the third control panel located in the flight deck. Most operators bought and galley in the aft part of the aircraft. Front toilet for the crew and the rear passengers are equipped with vacuum toilets with tanks increased capacity. The tank for clean water in the luggage compartment more inclusive than earlier models Gulftstream IV.The G450 have a more pleasant control compared with previous models Gulftstream IV. Dashboard PlaneView provides unparalleled situational awareness. Due to the transmission ratio of the booster aileron 7: 1, compared with a 5: 1 on the previous models achieved significant ease of control of the aircraft. The automated system reduces the workload on pilots, while the graphic synoptic systems maintain a constant awareness of the crew. But the plane is still prone to a hard landing due to the small horizontal tail and a small stroke of the elevator, which complicates the process of control of the aircraft in pitch.Many systems business jet G450, gone over here from the older models have been combined into automated management tools adapted to the ships G550. Pilots say that you must wait at least five minutes after connecting the battery, the system will take place until the initial inspection before turning the APU. At low temperatures necessary to warm the cabin air from the APU for 30-45 minutes to displays PlaneView heated to a temperature required for normal operation. Update the navigation database, which is performed once in 28 days using a laptop, it takes about an hour.In the daily operation of the pilots are planning the next flight, based on the average fuel consumption of 3,000 lb / hr (1360 kg / h). During the first hour of flight fuel consumption of 4,500 pounds (2040 kg), at the second hour - 3,000 pounds (1360 kg), the third and subsequent hours - about 2500 lbs / hr (1130 kg / hr). Business Jet can easily make flights lasting up to 9.5 hours with the fuel reserve balance conforming NBAA. Normal cruising speed at flight level of 0,82M, but long-distance flights cruising speed varies from 0,78M up to 0,80M depending on the weight of the machine.According to the pilots, the advertised basic operating weight (BOW) aircraft 43,200 pounds (19,600 kg) corresponds to reality at an average loading of the aircraft. If the business jet equipped with equipment for broadband Internet access, HDTV-wide monitors, solid wall at the rear of the cabin interior and other options, it may exceed the operating weight of 44,000 pounds (19,960 kg). But even with this equipment G450 can carry up to 8 people. full refueling.The reliability of the airframe, the aircraft systems and engines remains high. However, some pilots indicate greater complexity of systems management aircraft, which can cause certain problems that affect the provision of timely departure of the liner.Basic service interval is 12 months or 500 flight hours, depending on what occurs first. Carbon brake discs can withstand high temperature of more than 2000 landings. Planned repair each engine costs about $ 1 million., But his time between overhauls is 12,000 hours. Operators reported a technical problem with the central display, on-board computer (FMS CDU), backup batteries, controller, fire detection system in the engine, electric motor drive mechanism of horizontal stabilizer and APU starter.Major competitors business jet Gulfstream G450 - Bombardier Global 5000 aircraft and the Dassault Falcon 900EX / LX, wider than the fuselage 25 and 13 cm, respectively.The length of the cabin the Global 5000 is almost the same as in the G450, while the interior Falcon 900 is shorter than 1.16 m, the place here three sections with seating will not succeed. Both competitors are equipped with deflectable slats, so they have a better take-off performance compared to the G450.The Global 5000 can carry 8 people. at a distance of 9075 km at a cruising speed 0,82M. However, this is a big, heavier and less efficient aircraft. This lighter Falcon LX can carry 7 people. at a distance of over 8500 km. It is more economical, but its cruising speed in long-distance flights vary from 0.75 m to 0,78M.If you do not consider the flight and speed characteristics, the Gulfstream business jets outperform their competitors by unmatched technical support. And this is a critical indicator, if we consider the ratio of price - quality for the aircraft, privately owned.Since the recent announcement of the business jet G500 The G450 price decreases rather quickly, despite the fact that only five percent a year from more than 330 aircraft operated G450 sold currently.
