Winglet Tech Gets Updated STC For Sovereign Winglets
The upgrade will give Citation Sovereign owners and operators greater operational capability at high altitude.

Winglet Technology has received an updated STC for its Cessna Citation Sovereign transitional winglets and reprogramming the twinjet’s Honeywell Epic FMS for improved performance, including better second segment climb, en route climb, and cruise performance. The STC also increases the airplane’s mtow by 475 pounds to 30,775 pounds, and maximum zero fuel weight (MZFW) by 200 pounds to 21,000 pounds. Operations at the higher mtow and MZFW are permitted by the amended STC.
