I was wondering with all the T-0stroms and such going around...if the wind changed at an airport and the airport began doing a diffrent star and landing at a diffrent runway....what would the pilot do???...I would think he would change the STAR..but where would he get the STAR chart...or do they have them all in the cockpits???...but what about the runway....you have to put in info. for landing...do they also have charts for this?

Yeah OTTOL is right, the STAR is constant, it's just used as a transition from the enroute structure to the terminal area for increast efficiency and lower radio congestion.  And yes, pilots *should* always carry all applicable charts for their destination and alternate airports.  And, you'd only need to worry about STARS if you're a high performance aircraft, they usually deal with pretty high altitudes and such. 

And speaking of carrying all applicable charts, just the other day when I went on an IFR flight for training, they requested a stop and go, and then I  needed the approprate DP for the airport (You can deny SIDs and DP's, but since I was there, it was good experience, and luckily I had them all ready to go in the back seat)  so it's always nice to have everything out and ready.
