Narrative:

We were in a 777-200. It is rare for me to do a route that flies along [terrain]. I glanced at the route in operations on wsi. I liked that is looked best for weather so didn't question it. I noticed that we would be near [terrain] and would have to the depressurization route procedures when we got down there.as we approached the high terrain; we got out the books and started doing the FMC entries for the depressurization routes.we noticed that our filed route took us through an area on the FD pro chart labeled 'no fly area'. It is brown shaded; not red dashed as described in [operations manual] and has no explanation as to what planes it applies to. There was weather in that area so we deviated around the and also remained outside of that 'no fly' area.why does the flight planning software allow flights to be filed through charted 'no fly' areas? That seems like a set up for problems. I am bothered that I signed a release through a no fly zone; whether it was truly applicable or not.this highlights that this is a very cumbersome procedure. You need two or three ipads out next to each other to assimilate you need to do. The first difficulty is looking at the FD pro route and the depressurization route chart simultaneously to see where they coincide. Then you need to do the difficult swipe to see the route details; while also consulting the many page directions. In our case we were skirting many of the depressurization clouds so there was a lot of work and all this took most of our attention. One thing that would make all this easier would be to have our own ship position available enroute.[suggest] simplify the burdensome depressurization routes procedures where multiple ipads must simultaneously be up to input all the pertinent information. This also requires almost complete attention of bob pilots with the ipad sharing and discussing the programming especially on a route like this where we skirted numerous areas.
