Perhaps, Jeppesen was better at challenging the FAA TERPS office when their V-P in charge was named Terpstra. Jim is wonder of knowledge on the subject and, in my two meetings, a gentleman.
Knew Jim well and worked with him a lot. His successor is a sharp guy, too.
This has more to do with staffing levels and insights of past workerbees vs. present.
It is somewhat like the FAA staffs who design these procedures. They used to be pilots and used to be more accountable to the various FAA regions.
