Do you ever operate in USA airspace? Well if you do I'm sure you will know that it is expedient to have your high and low level charts out, as well as any area charts as you will frequently get clearance to obscure waypoints. The pressure really comes on when, on the Eastern seaboard, in winter, fog and snow everywhere and you are required to divert. Putting your alternate in Route 2 will be of limited help until you are at a reasonably high level, until then you can expect directions to waypoints you have never previously heard of and you may just find the charts useful. On a multi crew aircraft this shouldn't be a problem, one just has to remember rule #1, fly the aircraft.
Obviously when on one's home turf and in familiar surroundings a lot of what is on the charts will be committed to memory as well but I believe the charts should be available and not still snug in the Jeppesen holder in a bag behind your seat!
