Gulfstream Aerospace has added aircraft to the flight-test programmes of both the super mid-size G250 and ultra-large G650 business jets.
The third and final G250 test aircraft took off for the first time from Ben Gurion airport, Tel Aviv, on 28 June. It completed a 2 hour, 56 minute flight, reaching a maximum speed of 250 knots and a maximum altitude of 20,000ft. The G250 is being developed in collaboration with Israel Aerospace Industries (IAI) and the three aircraft will complete a 1,300-hour flight-test campaign.
The US manufacturer has now also added a fourth aircraft to the 1,800-hour G650 flight-test programme. The aircraft completed its maiden flight on 6 June, spending more than five hours in the air.
The latest G650 is the first production-standard aircraft, outfitted with a full cabin interior, which will be installed over the summer. The prototype is intended for cabin-systems testing and will continue flight-testing after the interior is installed.
