I highly recommend this book, It is a must have. I have learnt fast calculations I thought I'd never could without a calculator, I carry it with me always. Two thumbs up:-)

I was disappointed with this product. I ordered this book as a gift for a pilot who also teaches. I'm still going to give him the gift, but it looks as if I made it as a school project. Not high quality at all. And yeah, there's no index either. I really want to return this item, but I don't want to pay the return shipping fees.

P.S. If you click on the larger image of this "book," the image is actually larger than the real-life book.

The book does contain many of the generalized ways of quickly working some of the problems confronted by an aviator. I was disappointed in the quality of print and paper.
