Avionics companies L-3 and Avidyne will square off in court in February over L-3's claim that Avidyne copied some of its technology in the Entegra glass cockpit system. According to an Avidyne news release, the issue boils down to the method used to calibrate an electronic attitude indicator to correct for the alignment of the device in the aircraft. Avidyne denies the allegation and has countered that attitude indicator calibration was not a new technology.

L-3 first leveled the charge seven years ago and no longer has the rights to produce SmartDeck. It sold an exclusive license to Canada's Esterline CMC in 2010 to use the technology. Avidyne says that regardless of the outcome of the trial, the effect on customers will be minimal because only early model Entegra systems produced in 2004 and early 2005 are affected.
