Getting rid of the "are you sure..." messages

I tried to do a search for this but I wasn't really sure what to search for... didn't find anything.
Most of the time I use a plane (or whatever) in FSX that isn't using 100% new FSX-designed everything, I get prompted with "Hey, this is old, are you sure you want to use it?" Sometimes it's just one or two things, but it can be a fairly large amount of items.
I am wondering if and/or how people bypass, or ideally avoid, these aggravation inducing prompts. I know it's not much, but when I just want to hop in for a few minutes and I have to spend 5 minutes hitting "Yes" "Yes" "Yes" "Oh Baby" "Yes" "Yes" etc etc, it gets unhappy-fying. : (
Any help would be greatly, greatly appreciated.
