I’m no longer current but we used to have routing procedures for the Turkey/Iraq/Iran area and we also did have some fairly interesting escape routes (engine failure and/or for depress) for flights heading Europe-Beijing/HKG etc over north west China via overhead Urumqi.
As far as the OPs request goes problem is in addition to the proprietary nature of the documents there’s the problem that they were type/company specific due to, for example, the amount of oxygen (both pax and crew) we carried, so no guarantee they’d be valid on any of the types they mention.
