kuobin,
Perhaps you've confused the FMC with the Electronic Flight Bag (EFB) which will have the Airport Analysis incorporated. To the best of my knowledge, the EFB does not carry out the calculation, but simply stores electronically the AA data generated from another external source.
Current generation FMCs will give you little more than Balanced Field V Speeds for the weight and environmental conditions entered.
There's absolutely no reason why the FMC or EFB could not be programmed to carry out exacting Airport Analysis, it's only a software problem. If my PC at home can do it, then the squillion dollar FMCs and EFBs can also. Let's hope that future versions of the EFB will address this problem.
