747-400 Flightdeck
Obviously when the 747-400 first flew back in the late 80's the flightdeck was glass cockpit but fitted with CRT's (Cathode Ray Tube) screens as opposed to LCD screens. Two questions, basically have all these aircraft been retrofitted/equipped with LCD screens now or do the older ones that are in service still have the old CRT's? Secondly, were the newer production versions of the 747-400 fitted with LCD as standard? Any help would be appreciated, cheers!
