Remarks (Bemerkungen)
The G450 is an upgrade of the GIV-SP/G400, the best-selling business jet in its class. Design features are:

• repositioning of the main entrance door
• slightly longer fuselage than that of the GIV/G400
• PlaneView Cockpit, initially developed for the G550 / G500. An integrated avionics suite, PlaneView features four large 14-inch liquid crystal displays in landscape format – the first cockpit to incorporate this type of display. The unique implementation of Honeywell's Primus Epic architecture and display system provides substantially more display area than previous six-display designs while reducing the overall volume and weight of the equipment. PlaneView includes the first fully synchronous triple Flight Management System (FMS). In addition to impressive head-down displays, PlaneView incorporates the latest in Head-Up Display (HUD) technology with the next generation Visual Guidance System. The information and guidance cues provided by the VGS allow the pilot to easily control the aircraft without the need to look down at the instrument panel. Not just an additional primary flight display, VGS displays images from the Gulfstream Enhanced Vision System (EVS), the first of its kind to receive FAA certification, and is standard equipment on the G450.
• reliability improvements. The G400 Electrical Power System is replaced with a more capable and reliable system proven on the GV/G550. Two 40kVA Integrated Drive Generators and a 40 kVA APU Generator provide a significant improvement in electrical power capacity, no-break power transfer capability, and added redundancy for safe, reliable operation.
• a new version of the Honeywell 36-150 APU provides improved reliability for engine starting, better performance for cabin temperature control, and improved high altitude electrical power capacity.
• a new dual-pack Environmental Control System, based on the G550 air cycle machines and 3-zone digital cabin temperature control provides greater heating and cooling capacity for crew and passenger comfort.
• the new digital Engine Vibration Monitor card is integrated into the Primus Epic Modular Avionics Unit, providing additional automated engine balancing features, and interface with the PlaneView Maintenance Computer and Displays.
• Rolls-Royce has developed an improved Tay engine, designated the Tay 611-8C, which produces 13,850 pounds of thrust and was certified in December 2002 by the LBA. It is manufactured by Rolls-Royce Deutschland in Germany. This engine features a Full Authority Digital Engine Control (FADEC), improved larger diameter fan, modified high pressure turbine and new bypass/core mixer. These improvements have resulted in reduced fuel burn, increased operating margins, increased thrust for improved takeoff and climb performance, and extension of maintenance intervals to 6,000 hours midlife and 12,000 hours for full overhaul.

The G450 shares many of the same aircraft systems with Gulfstream's ultra-long-range G550 cockpit displays, ECS packs, pressurization system, electrical power, ECS, nose landing gear, nose wheel steering, oxygen and fire extinguishing systems – just to name a few. Additionally, the G450 pilot type rating is expected to be the same as the G550 pilot type rating with a minimal amount of additional training on the different engine models.

History (Geschichte)
Following the creation of a G550 prototype in 2001, Gulfstream began work on the G450, dubbed “GIV-X” at the time.
The first G450 test aircraft completed its first flight on April 30, 2003. Number two followed on 21 June and Number 3 on 22 June and Number 4 on 18 September 2003. Until October, the four aircraft had completed 58 test flights and had flown more than 150 hours with G450 test pilots and engineers testing the new onboard systems and the PlaneView flight deck. All major system development testing had been successfully completed and FAA Certification tests started.
The G450 was then unveiled on 6 October 2003 at the National Business Aviation Association's Annual Meeting and Convention being in Orlando, Fla.
At the official introduction in Orlando, Gulfstream expected to receive Federal Aviation Administration (FAA) Type Certification in the third quarter of 2004 and validation by the European Aviation Safety Authority in the fourth quarter of 2004. Deliveries are then to begin during the second quarter of 2005.
