Avionics
EGPWS patent trial begins this month
Rival avionics manufacturers are about to get their day in court.

Rival avionics manufacturers are about to get their day in court. Jury selection in the patent trial involving Honeywell and competing makers of terrain awareness and warning systems (TAWS) began October 31 in Wilmington, Del., and will be followed by opening arguments in the case starting on November 3.

Lawyers for Honeywell will argue in U.S. District Court that the defendants in the case–TAWS developers Universal Avionics of Tucson, Ariz., and Sandel Avionics of Vista, Calif.–are infringing patents applied in Honeywell’s enhanced ground proximity warning system (EGPWS), introduced in 1996.
