Gulfstream G600 Making Steady Progress To Certification With the first of the two new bizjet programs of Gulfstream reaching FAA certification status (that being the G500), the second model, the G600 is steadily making progress towards that same goal. The General Dynamics company updated the public about the progress of the G600. "We continue to make steady progress toward certifying the all-new G600 later this year and beginning customer deliveries in 2019," said Mark Burns, president, Gulfstream. "With the exceptional performance we’re seeing from the five flight-test aircraft in this program, I am highly confident our clients will be impressed with the aircraft we deliver. Its high-speed range, superior comfort and unmatched efficiency have already exceeded our expectations. Even at this stage in its development, the G600 is garnering attention, with its award-winning interior and seats, increased range capability and performance at high speed. The recent type certification for the G500 is added motivation and inspiration for us to bring the G600 across the finish line and into the hands of our customers."
