The focus of the last ten years, see figure 2 with the Boeing 787 Dreamliner, has shown that simplification is the way forward due to many human factors issues that have been addressed in past incident reports. Aircraft cockpits since the 1950s have become increasingly crowded, and the enormous amount of gauges in the SR-71 (figure 2) is a prime example of this. The only time a pilot would refer to many of the indicators at his disposal would be during a flight emergency, otherwise he would simply perform a quick scan and continue with his mission. The glass cockpit has been the answer for the past forty years, as seen in the Boeing 777, the F117 stealth fighter, and the Shuttle Atlantis (National Aeronautics and Space Administration [NASA], 2000). The glass cockpits feature liquid crystal displays that can be used to display multiple gauges and avionics screens that allow the user to customize the layout to their liking. According to Lane Wallace, a NASA author, states that a glass cockpit is a series of "displays capable of processing the aircraft's raw system and flight data into an integrated, easily understandable picture of the situation, position and the progress of the aircraft, not just horizontally." and vertical dimensions, but also in terms of time and speed” (NASA, 2000). Large planes aren't the only ones to use glass cockpits. Cessna, Piper, and Hawker Beechcraft, among others, began using glass cockpits between 2002 and 2003. According to the General Aviation Manufacturers Association (cited in NTSB, 2010b), “by 2006 more than 90% of new light piston airplanes were equipped with all-glass cockpit displays.” Glasscockpit had never been studied for safety factors until the NTSB started asking questions in 2010… mid. of the document...
