WAAS updates approved for Citation Ultras, Encores

By Janice Wood · July 18, 2011 ·

Cessna Aircraft Co. has received an STC for Wide Area Augmentation System upgrades for the Citation Ultra and Citation Encore.

The STC 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.

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.

“WAAS technology augments GPS systems and gives pilots five times the coverage and 12 times the accuracy of GPS-only systems,” Younger says.

WAAS gives pilots improved GPS 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.
