Multi Engine Study Guide

Welcome. I'm Jonathan Prentice.

I'm a flight instructor (CFI and CFII), a test pilot, and a former paramedic. If you're holding this guide, you're adding a multiengine rating, one of the most rewarding and most unforgiving steps in a pilot's training.

This guide goes deep on the material itself: why an engine failure turns into a loss of control, what Vmc really is, what you lose on one engine, and how the systems work. Chapters 1 to 12 are the subject matter. After them, every multiengine ACS Task is explained: what the ACS is asking, why, and where to find it.

The multiengine checkride is not about being brave. It is about being prepared. The examiner wants to see that you know your airplane's numbers, that you decide before you need to, and that you fly the airplane first, every time.

Use this guide alongside the current ACS, Flying Light Twins Safely (FAA-P-8740-66), the Airplane Flying Handbook, your airplane's POH or AFM, and your instructor. The numbers here are typical examples. Your airplane's manual is the authority. Fly safe, and exceed the standard.

Exceed the Standard.
