Citation Sovereign Mmo Increased to Mach 0.80

Cessna said flight testing of its wing design on the Citation Sovereign verified engineering data that increases the super-midsize jet’s Mmo from the originally announced Mach 0.78 to Mach 0.80. Currently, the three conforming Sovereign test aircraft have logged more than 670 hours in 370 flights. Airframe structural fatigue testing and the majority of static strength certification conditions have been completed. FAA certification is on track for the fourth quarter, with the first customer delivery scheduled for early next year. More than 100 Sovereigns have been sold, according to Cessna officials.
