Rat5,
That's an easy one to answer, because it is most times very hard to teach an old dog new tricks.
Quite a while ago, "we" came across an operator of glass B737 who would not allow use of LNAV/VNAV or moving maps except in cruise, and insisted on switching to only display a "conventional RMI" for departure and arrival. And insisted everything had to be "heading up", none of this flying "track" nonsense. INS/IRS/FMCS was too much like black magic for their liking, best stick to the "tried and true".
It turned out many oi their procedures went back to Viscounts, after all, what would Boeing know?? It was quite a job to culturally update by several generations all at once. The resistance to change was close to immovable, short of removing the management.
Tootle pip!!
