>> “...but also simple enough that you can't possibly need a whole book to explain it.” Graphic designer Paul Rand designed several logos during his long career which will be familiar to many people to this day. The deliverable for Rand was not just a mark, but also a presentation book (example [1]), which is different from the Style Manual describing how to use it. A dilemma for designers in business is how to justify costs of their designs. (Not much different from R&D I would guess). While it sounds like a good _idea_ to design cockpit in such a way pilots can be certified once and fly either plane, I could imagine an equally compelling argument the cost is too great compared to the cost of training (I have no idea why—maybe if training costs we’re somehow the burden of a secondary market—whatever). In which case you might need a great deal of research and maybe a book to make your argument? [1]: https://www.logodesignlove.com/next-logo-paul-rand https://www.logodesignlove.com/next-logo-paul-rand
