Changing the windspeed and direction

Hi all,
Well, I am getting there slowly!
Can anyone tell me how to manually change the weather at the departure/arrival airport.
I can input wind speed and direction but I cant submit it, it seems to be stuck on 270/02kts .
Also is there a way that you can set up an external camera at the arrival airport so you can replay and watch you stuff up the landing. This is a great and simple to use feature on Flight sim X.
Thanks for any help
