Glass Cockpit Generations
Hi all
I am currently doing some research around Glass Cockpits and would like some clarification around a few points. People sometimes refer to glass cockpits in 'generation' speak. The loose categories from what I have read are:
Gen 1: Separate CRT gauges with steam gauges used as well. What CRT gauges are used are dumb displays (eg Saab 340, ATR, Boeing 757/767)
Gen 2: Side by side CRT gauges with fewer steam gauges. CRT gauges used are semi-smart displays (eg A320)
Gen 3: Large CRTs used as sole gauges. Smart (integrated) displays (eg 777, Saab 2000, Bombardier Q400)
Beyond Generation 3, things become a bit more difficult to define. Can someone shed any light on what distinguishes gen 4 from 3, and also whether there is a gen 5?
Thanks
Rich
