Fully Digital Instrument Display Offered as Part of Citation II Upgrade

Sep 18, 2007

CONTACT: Glenn Kidd (978) 988-4639

WILMINGTON, MA - Clifford Development has incorporated the SENTINEL II Instrument Display System from AMETEK Aerospace & Defense as an integral part of its Supplemental Type Certification (STC) program for the Cessna Citation II (CE-550) aircraft and their recently announced Citation SII (CS550). The program re-engines the Citation aircraft with high-efficiency Williams International FJ44-3 turbofan engines. Clifford expects to achieve significant performance improvements from the retrofitted Citations, including increased range, cruising speed and fuel efficiency.

"Our SENTINEL II Instrument System is an ideal choice for Clifford's STC program. Their goal is to achieve best-in-class performance by marrying the latest in aircraft engine and avionics technology aboard one of the world's most popular business jets," comments Wes Hardin, Senior Vice President and General Manager of AMETEK Aerospace & Defense.

"The 3000-pound thrust Williams FJ44-3 engine utilizes full authority digital electronic control (FADEC) providing pilots with advanced engine diagnostics and monitoring, while our fully digital SENTINEL II with its dual redundant AMLCD displays accepts all standard aircraft input and output signals without requiring a major aircraft systems retrofit.

"Our SENTINEL II is fully redundant. Should a failure occur in either its data processing or its AMLCD display section, the other system is instantly ready to display all input parameters. In addition, its single box design offers savings in weight and space, while reducing cost and system complexity," adds Mr. Hardin.

"We are extremely pleased that AMETEK is a partner in our STC program," notes Jim Clifford, Chief Executive Officer of Clifford Development. "The SENTINEL II system is the perfect replacement for the original vertical tape engine instruments. Pilots will appreciate the range of easy-to-interpret engine data that the SENTINEL II draws from the Williams FJ44-3 FADEC system. This is just one of the more than 30 systems improvements."

The Williams FJ44-3 engine that powers the Citation IIs is the first FAA-certified engine of less than 6400 pounds thrust to incorporate dual channel FADEC and the smallest and lightest turbofan engine to have passed all of the rigorous FAA certification tests. AMETEK Aerospace developed a highly reliable combined total temperature/total pressure probe specifically for the advanced FJ44-3 engine.

Clifford Development, located in Kalamazoo, MI, was formed in 2006 to develop STC programs for installing the latest aircraft engine and avionics technologies across a broad range of existing high-value corporate and business aircraft.
