Long answer, it depends. In the big jets, on international flights we carry NGA charts for the entire world. However, some fields and locations have local or host nation developed procedures that you can download off military websites or have faxed to you. Sometimes they carry special aircrew qualifications. If we are flying to an airfield that doesn't have any NGA coverage, we use Jepps. We go to the Jepp website and print.

One habit I got into when flying to civilian or joint use international fields was that I always printed the Jepp charts for an airfield -- all of them. The parking spots, hold points, and other good-to-know information is not put into the NGA products. Knowledge is power.

If you knew in advance that you were going to use Jepp products, the specific procedures themselves had to be approved prior flying them -- even a stupid ILS approach. And the approval authority always approved procedures that you would never fly or would only approve VOR approaches and no ILSs usually due to terrain considerations.
