Promises Greater GPS Navigation Accuracy
Many Citation owners can now get an upgrade to their GPS nav
systems to give them the greatest accuracy possible. Cessna is
offering Wide Area Augmentation System (WAAS) upgrades for Citation
CJ1+, CJ2+, CJ3 and Encore+ aircraft as well as certain Citation
Excel and XLS aircraft. The modification is available at all nine
Cessna-owned Citation Service Centers.
Citation CJ3
WAAS gives pilots improved Global Positioning System (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.
"This is an opportunity for owners to significantly upgrade
their Citation's avionics capability," said Stan Younger, vice
president of Service Facilities. "When used properly, it's an
enhancement in both safety and operating capability, and is
available exclusively from our Citation Service Centers."
The WAAS upgrade is certified for installation via Service
Bulletin in CJ1+, CJ2+ and CJ3 models, Younger said, as well as
Citation Encore+ aircraft. It can also be fitted in Citation Excel
and XLS models equipped with UNS-1Espw Flight Management Systems. A
WAAS installation for the Citation Sovereign is expected to be
available later this year.
Owners may contact any of the company owned Citation Service
Centers to confirm their avionics suite is WAAS-compatible and
schedule an appointment. Actual installation typically takes about
10 days for CJ models and about two weeks for a Citation Excel or
XLS. Cessna is evaluating the possibility for installing WAAS in
other classic Citation models, Younger said.
