Gulfstream G280

In 2005, Gulfstream and IAI began designing a follow-on aircraft to the Gulfstream 200, the new model, known as the G250 was launched in 2008. Planned improvements included new glass cockpit and engines, larger wing, and heated leading edges.

The aircraft boasts several improvements, among them increased cabin length (external dimensions remain unchanged; the rear fuselage fuel tank was eliminated to add 17 inches (43 cm) of usable interior area), 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.

The business jet’s wing is a new design, using the Gulfstream G550 airfoil, and is larger (495 ft² vs. 369 ft² in the G200). This allows it 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. In July 2011, the G250 was renamed the G280, as the company had “determined that G280 is a more amenable number sequence [than G250] in certain cultures.”

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. The program was rescheduled with certification later in the year. It received full certification from Israel and the US on September 4, 2012.
