Alliant System Goes On a Conquest


Avidyne and S-TEC this week at AirVenture said they are working on an FAA STC to retrofit the Alliant Integrated Flight Deck into Cessna 441 Conquest II twin turboprops. The Conquest II installation will become the third airframe to offer the Avidyne Envision avionics and S-TEC IntelliFlight 2100 digital flight control system package. As with the STCs for the Beechcraft 90- and 200-series King Airs, the Alliant allows the panel to be updated with state-of-the-art situational awareness and safety tools at a relatively low cost. “We were approached by a Conquest II owner who had seen the Alliant package in a King Air and wanted the same high level of reliability, capabilities and redundancy for his aircraft,” said S-TEC Vice President of Sales and Marketing Greg Plantz. A Conquest II is currently being retrofitted with the system and the FAA STC paperwork is being handled at S-TECs headquarters in Mineral Wells, Texas.

The Alliant package for the Conquest II includes dual Avidyne EXP5000 10.4-inch primary flight displays (PFDs), Avidyne EX500 multifunction display (MFD), S-TEC digital autopilot and two-inch standby instruments. It has the capability of interfacing with most traffic, terrain, lightning, radar and radar altimeter systems.
