Built for Efficient ATPL Revision

The guide focuses on the information you actually need to understand and remember.

Complex subjects are broken down into shorter explanations, tables and step-by-step processes so you can quickly identify relationships between systems rather than simply memorising isolated facts.

You’ll also find sections such as:

EXAM TIP – useful recognition techniques and points worth remembering.

COMMON EXAM TRAP – concepts and wording that are easy to confuse.

MUST MEMORIZE – information worth committing directly to memory.

UNDERSTAND, DON’T MEMORIZE – concepts that become much easier once you understand how the system works.
