the current generation only wants to look at the FMS.

I believe one of the reasons why lots of pilots are not aware of some performance and their related graphs is that they are not distributed to the pilots.
A simple flight planning and performance manual would show all relevant graphs to crews and I could ask how many of my colleagues have it...maybe 10%?5%?
I think it is the Airline responsability to distribute all manuals readily available to their crews and not only the usual FCOms..
