Sorry, the older book I used was the AFE book, not the Pooleys. So even if I used the Pooleys Air Law book back in 2008, the content I am referring to would still be missing from the book. I'm also guessing the latest AFE books would still contain the material also.
I guess I could find information on fuel and wake turbulence in AICs, the only problem is I am concerned that there is other information I need to be aware of, but is not present in the book and I simply have not picked up on its absence.
