I've "done" aircraft electrics/electronics from WWII surplus in the '50s to Concorde to helicopters to Mirages.... and somehow I've never come across 112V DC.
Only just discovered the Valiant used it, and the Trident.
Does anybody here know the hows and whys and wherefores, and when it first came into use, and when it faded out?
Is it more or less UK-only, or do other examples exist?
Just curiosity (.... and wondering how I missed it all those years
).
