For Southwest Airlines, there are no replacement plans—at least for now—for the electromechanical cockpits on the 130 Boeing 737-300s and -500s it still flies. “We are always evaluating the future of our 737-300s and -500s, which includes possible cockpit modifications as fleet planning warrants,” says Kent Horton, Southwest's director of engineering.
Southwest Airlines is beginning to run up against reliability, parts obsolescence and supply challenges with the attitude display indicator (ADI) on the 737 Classic fleet, says Kent Horton, Southwest’s director of engineering.
