FCOM 2 and 3, what do we need a lot of it for?

[meatlover]

Understand why FCOM1 is very important, and though it's impossible to know it inside out, it's good to keep reading and gaining knowledge about the airbus systems.

I read what I could understand with the FCOM 3 as I believe it is important during flight, but seem to forget a lot of it as it includes a lot of numbers.
Disregarding the SOP's which I know should be memorized with time, what exactly do we need to know from the FCOM3?
If I am not wrong, the QRH covers everything we will need, and we need not to remember the numbers.
More importantly WHERE to find the content in the cockpit. Is this correct?

How about the FCOM 2.

I seem very lost in how to go about while studying all of this.
If someone can please guide me, thank you.

Both FCOM 2 and 3 have a lot of useful information in them.

FCOM 2 is required for all your contaminated PERF. It also contains various procedures that you may need to refer to, for example flight with the gear down etc and lots more!

FCOM 3 has lots of good stuff too. Limitations, expanded checklists, SUPP techniques, useful for manual engine starts, cross bleed starts just to name a couple.

From an operational point of view, as you become more experienced as an airbus pilot you will learn your way round the manuals.

You don't need to be a real world pilot to find appeal in realistic operation of the aircraft.

I know that much of the information I divulge is not useful in my hobby, let alone in practical life, but I still enjoy reading about it and having a clue. That is aviation and other.

That said I will admit that the A320 family is the one most lacking a decent rendition for desktop simulation from the usual narrowbody suspects.
