Honeywell’s KFD 840 gets STC

December 2, 2009

Honeywell International has just earned supplemental type certificate (STC) approval to install its new KFD 840 primary flight display (PFD) on more than 50,000 general aviation aircraft. The approved model list (AML) includes virtually all Beech, Cessna, and Piper singles and light twins. Mooney models M20L, M20M, M20S, and M20R are also included.

The KFD 840 is part of Bendix/King’s Apex Edge series of avionics. The 840 is designed to replace the traditional “six-pack” of analog flight gauges, and provides a single, large display with vertical tapes for airspeed and altitude information, a weight and balance calculation function, and is compatible with many popular GPS navigation receivers and autopilots. The unit comes with its own attitude and heading reference system (AHRS), which means that the system is capable of providing its own flight guidance—even if GPS, air data, or vacuum sources are inoperative.

Honeywell says the $16,995, eight-pound PFD will fit in many piston aircraft without major modifications to the panel or existing electronics.

“The KFD 840 will be upgradeable with features such as Honeywell’s SmartView synthetic vision system,” said Chad Cundiff, vice president of the company’s Crew Interface Systems. “Honeywell’s synthetic vision technology has been flying as part of Primus Epic, and the Apex Edge series was designed to bring our advanced synthetic vision technology to general aviation pilots in this segment.”
