Thanks CJ for the PVD explanation.
But what are the advantages the L1011 AP has over other autoland and AP systems? What does it do better than for instance the 747-classic AP? Or do you consider it to be even superior over modern ( A330, B777 ) systems?
I'm not criticising, just wondering what it is that makes it so special.
