Checkride Oral Exam Prep
Multi-Engine Rating (ME) Checkride Oral Prep
The Multi-Engine Rating checkride oral focuses on the aerodynamics and procedures unique to multi-engine aircraft. Your DPE will test your understanding of Vmc (minimum controllable airspeed), critical engine concepts, engine failure procedures at different phases of flight, and multi-engine aircraft systems. This is one of the most technically demanding oral exams.

The multi-engine oral typically lasts 1-2 hours. Expect thorough questioning on Vmc and every factor that affects it, critical engine identification, engine failure procedures (before and after Vmc, on takeoff, in cruise, on approach), propeller feathering, and zero-sideslip concepts. DPEs want to see that you understand the aerodynamics behind why multi-engine flying has unique risks and how to manage them. Performance calculations for engine-out scenarios are also commonly tested.

Frequently Asked Questions
What is Vmc and why is it important for the multi-engine checkride?
Vmc is the minimum control speed with the critical engine inoperative — the slowest speed at which you can maintain directional control. It is the most heavily tested topic on the multi-engine oral. You must know the definition, all factors that affect it (density altitude, weight, CG, gear, flaps, bank angle, prop condition), and the associated ACS demonstration conditions.
What engine failure procedures should I know for the multi-engine checkride?
Know the memory items: mixtures, props, throttles, flaps, gear, identify (dead foot = dead engine), verify (throttle to idle), and feather. Understand engine-out procedures at different phases: on takeoff before Vmc, after Vmc, during climb, in cruise, and on approach. Know when to abort vs. continue, and single-engine service ceiling implications.
How long does the multi-engine checkride take?
The multi-engine rating checkride typically takes 1-2 hours for the oral exam and 1-1.5 hours for the flight test. The oral focuses on multi-engine aerodynamics, Vmc, critical engine, engine failure procedures, and systems specific to your training aircraft. The flight test includes engine failures during various phases of flight, Vmc demonstration, single-engine approaches, and single-engine go-arounds.
What is the critical engine on a conventional twin?
On a conventional (clockwise-rotating propellers) twin-engine airplane, the left engine is the critical engine. This is because when the left engine fails, the right engine's thrust is farther from the centerline due to P-factor, creating a greater yawing moment. This means the airplane is harder to control with the left engine inoperative. Counter-rotating propellers (like on some Beechcraft Barons) eliminate the critical engine concept.
Do I need a multi-engine rating before applying to airlines?
Yes, virtually all airline pilot positions require a multi-engine rating. Most regional airlines require a Commercial Multi-Engine certificate at minimum, and major airlines typically require an ATP with a multi-engine class rating. Many pilots earn their multi-engine rating during flight training and build multi-engine time as flight instructors (with an MEI) or through Part 135 operations.
