Not the groundschool books, the ones about the flying exercises. For example...
Or electronically...
(There, that was impartial wasn't it?)
Anyhow, question to the instructors who have had their students use one or more of these books - presumably instructing reading up on exercises before flying them, then just using the brief as a recap and Q&A session.
Do they help? Would you recommend using books or software like this, and if so what's your favourite, and how do you find they work best?
