This book was designed to simplify and summarize the major concepts of the subject matter, based on the experience of both airline pilots and aircraft dispatchers of commercial companies, all professionals of the highest level.

The teaching methodology offered by our books proposes not only to cover simple theoretical contents, but also advanced practical concepts, trying to place each reader in the position of a real pilot performing his daily work, where he can find different challenges, and among them, the enormous challenge of making operational decisions based on the calculations made in the different performance tables.

The ultimate goal of this manual will be to provide each reader with the necessary tools to be able to interpret a certain table of limitations, its variables and its different configurations. We will learn to interpret the different calculations of each stage of a flight, take-off, cruise and landing.
