Innovative Solutions & Support, Inc. (NASDAQ: ISSC - News) today announced that the first Cessna Citation aircraft retrofitted with its AdViz Flat Panel Display System has successfully completed its initial flight test.

In January 2007, Cessna Aircraft Company chose Innovative Solutions & Support (IS&S) as the flat panel display system provider for the Cessna AdViz Glass cockpit retrofit program. Cessna and IS&S wanted to replace aging flight instruments on legacy Citations with the AdViz system, resulting in reduced weight; improved reliability; and access to navigational aids, such as XM Weather, navigation charts, remote radio tuning, and enhanced video. The AdViz system will initially be available for purchase through the nine Cessna-owned Citation Service Centers, and will later be distributed through the Cessna authorized network. It will be certified for the Cessna Citation 500/501, 550/551, S550, 560, and 650 aircraft.

The first successful flight of the retrofitted Citation V was made on April 6, 2009. "The AdViz Glass cockpit exceeded my expectations," says Rick Trissell, Cessna Flight Test Pilot after a 1.5 hour flight. "The crisp symbology and clarity of the displays, along with additional navigation aids, will enhance situational awareness in flight."

"The success of this flight is a great achievement," says Chad Thorne, Vice President Business Development and Marketing of IS&S. "We are pleased to have the opportunity to work with Cessna Aircraft Company, and look forward to providing pilots and passengers with this state-of-the-art technology to improve the efficiency, reliability, and safety of flights."
