But I'd rather have it in date now even if it will go out of date soon, so that when I don't update the AIRAC its not too far afield to the current AIRAC.
My 777 and 737 both still have AIRAC 1309, so I'm not sure that's how it works. (I don't have Navigraph)
I'm confident the 777 came out much more recently than 2009. Just out of curiosity which AIRAC do you PMDG products have??
