Wide Area Augmentation System (WAAS) upgrades are available for the Cessna Citation Ultra and Citation Encore, the Wichita planemaker said in a news release Thursday.

The supplemental type certificate covers all Citation Ultras and Citation Encores serial number 260 through 750 with an upgrade to dual Universal UNS-1Espw Flight Management Systems certified for fully coupled WAAS LPV approaches. Previous WAAS updates were approved for CJ1+, CJ2+, CJ3 and Citation Encore+ models, as well as Citation Excel and XLS aircraft.

The WAAS upgrades can be performed at any of the nine Cessna-owned Citation Service Centers in North America and Europe, according to Stan Younger, Cessna's vice president of Service Facilities. Owners may contact any of the centers to confirm their avionics suite is WAAS-compatible and to schedule an appointment.

"WAAS technology augments GPS systems and gives pilots five times the coverage and 12 times the accuracy of GPS-only systems," Younger says. "This new after-market capability for our classic Citations also demonstrates the company's commitment to the on-going success of Citation owners and operators for years to come."

WAAS gives pilots improved Global Positioning System navigation accuracy, allowing for greater access to many airports during difficult weather conditions. WAAS LPV approaches are similar to ILS performance; with some LPV (localizer performance with vertical guidance) procedures having minimums as low as 200 feet.
