I don’t see how that compares to flying a plane? I could ask, “How does a blind person catch a baseball?” Which would be a closer analogy than reading a book. I understand that aircraft instruments might be able to be made in some sort of Braille form, or perhaps they could “talk” (although there are several instruments that need to be “read” pretty much at the same time (altimeter, airspeed indicator and artificial horizon, to name three). But even in IFR conditions there is taxiing and at least some need for vision, especially at landing.
