![]() Variables selected for analysis included accident severity, weather, time of day and the purpose of the flight. Of the 8,364 airplanes included in the study, 2,848 had conventional cockpit displays and 5,516 had glass cockpits. The report says that the accident data analysis of conventional versus glass light airplanes included “(1) a comparison of specified aircraft models manufactured during the five years from 2002 through 2006, the years that spanned the transition of the fleet from conventional to glass cockpit displays, (2) statistical comparisons of retrospective accident data for the years 2002 through 2008 by display type, and (3) a comparison of aircraft and flight activity data obtained from the FAA aircraft registry and an analysis of GAATAA Survey data for the years 20.” Accident data came from the NTSB Aviation Accident Database. “The introduction of glass cockpits has not resulted in a measurable improvement in safety when compared to similar aircraft with conventional instruments,” the study says. ![]() ![]() The “glass cockpit,” in which the electronic displays integrate aircraft control, autopilot, communication, navigation and systems monitoring, represents a significant change for general aviation.īut does the glass cockpit make flying light aircraft - defined here as having a maximum gross weight of 12,500 lb/5,700 kg - safer? So far, no. Thanks to trickle-down technology, new light aircraft have undergone a transition from analog flight instruments to computer screens similar to those on modern transport category aircraft.
