All well and good Major, but when it comes to our upgrades and PPCs and line checks, we had best know every little FCI/FCN and change to the ever changing FOM or OM-whatever this week. Lest you will find yourself with several well known TREs that have memorized every dot and dishdash of said documents and will grade you accordingly. Here, as long as nothing gets dinged up, it's not how you fly, or conduct CRM, but how well you know (re. memorise) the books. Some (and I say just few) TREs seem to make up with "book" knowledge what they lack in real world experience. You know that. However in the real world, your post makes an outstanding point IMHO.
