Contingency fuel...

When using the Jeppesen flt planning system to calculate max payload, fuel required for given payload etc. Why does the system assume that the 5% contingency fuel is burnt by the time you arrive. The fact is that this fuel is a buffer of extra fuel in case the situation arises where you might need it, but if this situation doesnt arise, then you arrive at your destination with it still in the tanks. If you are arriving at max landing weight, the reality is that you are arriving at your max landiing weight, plus the weight of the contingency fuel. In other words an overweight landing, which could be several tons over your max ldg wt. This is concurred when the loadmaster completes his loadsheet, where the maths don't lie. His loadsheet in this case will show an overweight landing...
