The Citation Longitude was introduced in May 2012 at EBACE. It offers the same clean sheet fuselage cross section as the smaller Citation Latitude but is much larger and features an all-new gently swept wing with winglets.
The Longitude is powered by two Honeywell HTF7700L engines and features the same Garmin G5000 avionics suite as the Latitude. The Longitude competes with the Embraer Legacy 650 and the Bombardier Challenger 605.
The first flight was October 8, 2016.
