An air carrier pilot commented that a company policy preventing carriage of personal air navigation supplemental data in addition to the company supplied commercial ship-set navigation charts was removing a level of safety because pilot acquired knowledge was no longer available.

Narrative:
While the new ship-sets have a number of real advantages and positives I have major concern for a very negative safety aspect involved with the ship-set concept. When I reviewed the crew briefing prior to my departure I was taken back by a recent entry that indicated no personal plates or charts were to be carried during routine line operations. This directive has major negative safety implications; let me illustrate. On the arrival into an international destination crews are dealing with a number of factors that impact the safety of the operation. Language; unclear communication; fatigue; metric altimetry are some major factors. Introducing confusion because useful pilot footnotes obtained through experience have been removed is very bad. Let me illustrate further. Inbound the commercial approach plate leaves something to be desired. The fix D22 XXX is coded in the FMC as D082V; fix D8.1 XXX is D082H. I learned this from operating into and out of this field on many occasions and making appropriate notes on my pages. To take this type of useful information away from line pilots represents a negative safety factor.
