The Gulfstream G280 is an twin-engine business jet built under license by IAI in Israel for Gulfstream Aerospace. It began delivery to users in 2012. ==Design and development== In 2005, Gulfstream and IAI began designing a follow-on aircraft to the Gulfstream G200. The new model, named ''G250'', was launched in 2008. Planned improvements included new glass cockpit and engines, larger wing, and heated leading edges.〔"Gulfstream raises the bar with the G250". ''Flight International'', October 7–13, 2008, p. 27.〕〔("NBAA 2008: Gulfstream know-how buoys G250 performance claims" ). Flight International, October 5, 2008.〕 The aerodynamic design of its wing and empennage, and design of the interior and completion components were performed by Gulfstream. Detailed design was performed by IAI to Gulfstream's requirements. It is a Gulfstream designed aircraft under a new type certificate.〔("Gulfstream Scores Double Win with G280, G650 Certification" ). AIN Online, October 2012.〕 The aircraft has several improvements, among them increased cabin length (external fuselage dimensions remain unchanged; the rear fuselage fuel tank was eliminated to add 17 inches (43 cm) of usable interior area),〔("Flying the Gulfstream G280" ). Aviation Week & Space Technology, October 29, 2012. Accessed January 17, 2013〕 new engine HTF7250G, new T-tail (with larger horizontal and vertical stabilizers), wing anti-ice provided by engine bleed air, cabin with four more windows and access from the cabin to the baggage compartment. It competes against the Hawker 4000, Bombardier Challenger 300 and the Embraer Legacy 500. The fuselage, empennage and landing gear are manufactured by IAI, the wing by Spirit AeroSystems, and the aircraft is assembled in Israel. It is then ferried to Dallas, Texas, for interior finishing and painting.〔〔〔 Its wing is a new design, using the Gulfstream G550 airfoil, and is larger (495 ft² vs. 369 ft² of the G200). This allows the business jet to climb directly to 43,000 ft. Design cruise for the new airfoil is Mach 0.80, vs. Mach 0.75 for the G200 wing.〔 The G250 took its maiden flight on December 11, 2009 in Tel Aviv, Israel.〔Egozi, Arie. ("Gulfstream G250 performs first flight successfully" ). Flightglobal.com, December 11, 2009.〕 In July 2011, the G250 was renamed the ''G280'', as the company had "determined that G280 is a more amenable number sequence (G250 ) in certain cultures."〔(Gulfstream rebrands its G250 the G280 )〕〔("GULFSTREAM RENAMES G250" ). Gulfstream〕 The G280 was provisionally certified in December 2011 by Israel.〔 In July 2012, the US FAA released a report with conditions to ensure no security gaps in the G280's electronic systems.〔(【引用サイトリンク】title=FAA Warns of Gulfstream Electronic Security Gap )〕〔("GULFSTREAM G280 POISED FOR CERTIFICATION" ). ''Gulfstream Aerospace'', August 15, 2012.〕 It received full certification from Israel and the US on September 4, 2012.〔Sarsfield, Kate ("Israel and USA grant full certification for Gulfstream G280" ). ''Flight International'', September 4, 2012.〕 After the flight test program, the G280 demonstrated a range of 3,600 nmi (6,667 km) at Mach 0.80 with four passengers and NBAA IFR reserves in 2011. It can fly from London to New York or Singapore to Dubai. Its balanced field length has been reduced to 4,750 feet (1,448 m) from the G200's 4,960 feet (1,512 m).〔().
