Q. Can this be added to the additional education expenses section of books and materials REQUIRED to be purchased from the school?
A. No Even though the school may have dictated where you took the training, that doesn't count as "required to be purchased from the school".
However, since it's a degree requirement, I do think it qualifies as "course materials not required to be purchased from the school". This means it does qualify for the American Opportunity Credit, but not the Lifetime Learning Credit (LLC)*.
*It the flight school, itself, was an "eligible institution" then the flight tuition would qualify for the LLC.
