The use of tailored RNP charts was an expensive proposition - millions per year in licensing fees. Not sure these days but last time I looked it was difficult, if not impossible to justify on the basis of the savings you would make by avoiding diversions. It might be all different with Naverus being taken over by GE, I don't know.
The charts had a significant fee for access each month and given the significant training impost I couldn't see the value in it. Still don't quite frankly.In Queenstown definitely, but not too many other places...
Yes it is great having the capability but do you really get value for your money in an environment where every capability had to fight for funding? I suspect not but I think it got to the point where in order to "keep up with the jones" (or perhaps keeping up with Alex😄
it needed to be done.
