+xYes, if you let us know of a mountain pass that you think we should have but don't, we can add it.
Are these passes present on some other chart you're consulting?
Yes, for example on the
"Aeronautical Chart VISUAL 500" Austria/Österreich, published from DFS Germany.
I'm shure, they will hand hand off a list (high and coordinates) to you with the most important passes.
