"WorldDC10"
This was on the original World DC10-30 fleet from the factory back in 1979, so yes, probably not on today's fleet mix. As you say, pilots probably found it wasn't that helpful, plus it was a complicated system as you can see from BAe146's posts, so why keep the weight and the maintenance headaches..
"BAe146s make me cry"
Looks like it was another one of those good ideas at the time but...
Thanks to all for the comments.
