The new G250 business jet that IAI builds in partnership with Gulfstream Aerospace is continuing the flight-test program that it started on Dec. 11, 2009. In recent flights, the aircraft has flown up to 40,000 feet at speeds of up to Mach 0.85 as it heads for planned certification before the end of 2011.
Three aircraft will log about 1,300 hours in the planned flight-test program. Performance objectives for the G250, powered by two Honeywell HTF7250Gs each rated at 7,445 pounds thrust, include Mach 0.85 Mmo, maximum altitude of 45,000 feet and 3,400-nm NBAA IFR range at Mach 0.80. Its new transonic wing, T-tail, Rockwell Collins PlaneView 250 cockpit and two additional cabin windows (19 total) are the main features that set it apart from the G200.
The elimination of the G200’s aft-fuselage fuel tank increases the usable volume of the cabin and provides in-flight access to the baggage compartment. The airplane’s base price is $24 million (2008).
