What’s on the Multi-Engine Checkride? (ACS, FARs, and What You’re Actually Tested On)

The Multi-Engine Checkride tests far more than the ability to fly a twin-engine airplane. Learn what the FAA ACS requires, what to expect during the oral and flight portions, how VMC and engine failures are evaluated, and which mistakes commonly cause applicants problems.

Preparing for a Multi-Engine Checkride can feel significantly different from preparing for earlier practical tests. The airplane is faster and more complex, systems require greater attention, and an engine failure introduces aerodynamic and performance problems that simply do not exist in a conventional single-engine trainer.

Fortunately, what the examiner expects is not a mystery. FAA practical tests are conducted using the applicable Airman Certification Standards (ACS), which integrate aeronautical knowledge, risk management, and flight proficiency. The current FAA ACS library includes standards for Private Pilot, Commercial Pilot, Instrument Rating, ATP, and Flight Instructor certification, so the exact tasks applicable to a multi-engine practical test depend on the certificate or rating being sought.

The important point is that a multi-engine checkride is not simply about demonstrating maneuvers. The examiner wants to determine whether the applicant understands the twin-engine aircraft, can recognize and manage its unique risks, and can make safe decisions when one engine is no longer producing thrust.

The Two Parts of the Multi-Engine Checkride

Like other FAA practical tests, the Multi-Engine Checkride includes an oral evaluation and a flight portion. Knowledge, risk management, and practical skills are interconnected throughout the test rather than existing as completely separate subjects.

During the oral portion, applicants should expect scenario-based questions rather than relying exclusively on memorized definitions. The examiner may combine weather, aircraft loading, runway conditions, systems, regulations, and engine-out performance into a realistic flight scenario and ask the applicant to explain whether and how the flight can be completed safely.

The flight portion then requires the applicant to demonstrate the applicable maneuvers and procedures to ACS standards while maintaining situational awareness, aircraft control, checklist discipline, and sound aeronautical decision-making.

What Is Tested During the Multi-Engine Oral Exam?

A major objective of the oral examination is determining whether the pilot understands what changes when moving from single-engine to twin-engine aircraft.

Knowing that VMC is minimum control speed or that VYSE is best single-engine rate-of-climb speed is not enough. An examiner can reasonably expect the applicant to explain why those speeds matter, what influences them, and how they affect decisions following an engine failure.

Aircraft-specific knowledge is equally important. A pilot should understand the airplane being used for the practical test well enough to recognize abnormal indications, manage systems correctly, and explain the consequences of a failure.

1. Regulations and Pilot Qualifications

The applicable regulations depend partly on the certificate or additional class rating being sought, so pilots should prepare using the regulations referenced by their specific ACS rather than treating a generic list as the complete test syllabus.

Relevant subjects may include pilot privileges and limitations, endorsements, required documents, airworthiness requirements, equipment requirements, maintenance status, operating limitations, and applicable IFR requirements when instrument privileges are involved.

Applicants should understand how the regulations apply operationally instead of simply memorizing FAR numbers. An examiner may present a realistic scenario and ask whether the pilot, aircraft, weather, equipment, and proposed operation satisfy the applicable requirements.

The FAA maintains the current certification standards through its official Airman Certification Standards library, which should be the primary reference when preparing for the practical test.

2. Twin-Engine Aircraft Systems

Aircraft systems are a major component of multi-engine knowledge because system failures can interact directly with engine-out performance and pilot workload.

The exact systems depend on the aircraft used for training and testing, but applicants should generally be prepared to discuss:

  • engines and engine controls;
  • propellers and feathering systems;
  • fuel tanks, selectors, pumps, and crossfeed where installed;
  • electrical generation and distribution;
  • landing gear and emergency extension;
  • hydraulic or vacuum systems where applicable;
  • heating and ventilation;
  • anti-icing and deicing equipment where installed;
  • fire detection or suppression equipment where installed;
  • avionics and associated electrical limitations.

The objective is not simply identifying components. The applicant should understand what happens when something fails.

For example, an alternator failure should lead naturally to a discussion of electrical load management and available battery endurance. A fuel-system question may develop into a discussion of fuel starvation, crossfeed limitations, or engine restart procedures. A propeller question may lead directly to feathering and the effect of a windmilling propeller on single-engine performance.

The FAA’s multiengine guidance specifically covers subjects including feathering propellers, fuel crossfeed, electrical generation, autopilots, yaw dampers, anti-icing equipment, performance, and weight and balance.

3. Multi-Engine Performance and Limitations

Performance is one of the most important areas of the Multi-Engine Checkride because losing one of two engines does not mean the aircraft simply retains half of its normal performance.

Climb performance depends on excess power. Consequently, losing approximately half the installed power can eliminate a much greater proportion of the aircraft’s climb capability.

Applicants should understand how single-engine performance changes with aircraft weight, density altitude, temperature, configuration, propeller condition, and other operational factors. A twin that demonstrates acceptable engine-out performance on a cool day near sea level may perform very differently when heavily loaded at a high-elevation airport.

Performance charts in the aircraft’s POH or AFM therefore matter. An applicant should be able to use actual aircraft data rather than relying on assumptions about what a twin “should” be capable of doing.

Understanding VMC

Few subjects are more closely associated with multi-engine training than VMC, and an applicant should expect detailed questions about it.

VMC is the minimum control speed with the critical engine inoperative under specified certification conditions. More importantly for the checkride, the pilot needs to understand the factors that affect directional control and why actual conditions can change the available control margin.

The examiner may ask how power, density altitude, center of gravity, bank angle, propeller condition, aircraft weight, and configuration influence the situation.

Simply pointing to the red radial line on the airspeed indicator is therefore not enough.

The FAA’s Airplane Flying Handbook devotes substantial attention to both VMC and VYSE because directional control and obtaining the best available single-engine performance are fundamental to safe multiengine operation.

Understanding VYSE

VYSE is the best single-engine rate-of-climb speed under the applicable conditions and is commonly associated with the blue radial line on many light twin-engine airplanes.

During training, pilots quickly learn “blue line,” but the checkride requires understanding what the speed actually represents.

After an engine failure, allowing airspeed to deteriorate while attempting to maintain altitude can create a dangerous situation. The aircraft may transition from a performance problem into a directional-control problem as speed decreases and asymmetric thrust remains high.

A competent multi-engine applicant therefore needs to understand the relationship between airspeed, asymmetric thrust, directional control, drag, and single-engine climb capability, rather than treating each V-speed as an isolated number.

4. Critical Engine and Asymmetric Thrust

Where applicable to the airplane, the applicant should understand the concept of a critical engine and the aerodynamic factors that make the failure of one engine more detrimental than the other.

This can involve P-factor, accelerated slipstream, spiraling slipstream, and torque depending on the aircraft configuration. Counter-rotating propeller designs can alter or eliminate the conventional critical-engine relationship.

What matters during the checkride is being able to connect aerodynamic theory to aircraft behavior. If one engine fails, the pilot needs to understand why the aircraft yaws, why rudder is required, why a small bank toward the operating engine may improve performance when specified, and why decreasing airspeed can eventually make directional control impossible.

5. Engine Failure Procedures

Engine failures are central to multi-engine training and therefore receive substantial attention during the practical test.

Applicants should be prepared to discuss and demonstrate appropriate responses to failures occurring during different phases of flight, including a failure during the takeoff sequence, after liftoff, during climb or cruise, and during approach.

The exact procedure is always aircraft-specific, but the fundamental priority remains aircraft control.

The pilot must maintain directional control and an appropriate airspeed before becoming absorbed in identifying or troubleshooting the failure. Once the airplane is stabilized, the failed engine can be identified and verified according to the approved procedure before being secured when appropriate.

This sequence matters because shutting down or feathering the operating engine is one of the most serious errors a pilot can make during a genuine engine failure.

Identify, Verify, Then Secure

The familiar “dead foot, dead engine” memory aid can help identify the suspected failed engine because the foot that is no longer applying significant rudder pressure generally corresponds to the failed side.

But identification is not verification.

Before feathering or shutting down an engine, the pilot should verify the suspected failure according to the procedure for the specific aircraft. The objective is to prevent a rushed response from turning a manageable one-engine-inoperative situation into a complete loss of useful power.

The examiner is therefore evaluating more than checklist memorization. They are looking for disciplined aircraft control, deliberate identification, proper verification, and appropriate use of the checklist.

The Flight Portion of the Multi-Engine Checkride

The practical flight portion evaluates both normal aircraft operation and the applicant’s ability to handle the distinctive hazards associated with multiengine airplanes.

The exact tasks depend on the certificate or rating and the applicable ACS, but pilots should prepare for normal operations, performance maneuvers, aircraft handling, and emergency operations involving simulated powerplant failures.

The FAA’s Airplane Flying Handbook covers normal and crosswind takeoffs, short-field operations, rejected takeoffs, slow flight, stalls, approaches, landings, and extensive engine-out procedures within its multiengine chapter.

Normal Takeoffs and Landings

Not everything on a Multi-Engine Checkride involves a failed engine.

The applicant must still demonstrate precise normal aircraft operation. This can include appropriate takeoffs, traffic-pattern operations, approaches and landings while demonstrating proper checklist use and aircraft control.

The difference is that the pilot is now operating a generally faster and more complex aircraft. Power management, propeller controls, landing gear, configuration changes and additional systems increase workload compared with many primary single-engine trainers.

Good cockpit organization therefore becomes particularly important.

Slow Flight and Stalls

Depending on the applicable ACS tasks, aircraft handling may include slow flight and stall-related demonstrations.

These exercises are particularly valuable in a twin because they reinforce recognition of deteriorating airspeed and aircraft energy. During an actual asymmetric-power situation, allowing speed to decay while maintaining high power on the operating engine can significantly reduce the directional-control margin.

The objective is therefore not merely performing a maneuver to a numerical tolerance. The pilot must demonstrate awareness of energy, coordination and aircraft limitations throughout the exercise.

Simulated Engine Failure

A simulated engine failure is one of the defining elements of multi-engine training.

The examiner wants to see an organized response rather than frantic movement through memorized controls. The applicant should recognize the failure, maintain directional control, establish the appropriate airspeed, manage configuration, identify and verify the failed engine, and complete the appropriate procedure.

Equally important is judgment. The applicant needs to understand whether the aircraft is capable of climbing, maintaining altitude, or only descending under the simulated conditions.

Trying to force an aircraft to climb when the available performance does not support it demonstrates poor engine-out decision-making even if the checklist itself is remembered correctly.

VMC Demonstration

The VMC demonstration is one of the best-known maneuvers associated with multi-engine training.

Its purpose is not to teach pilots to fly around at minimum control speed. Instead, it demonstrates how directional control deteriorates as airspeed decreases under asymmetric power and teaches pilots to recognize and recover before the aircraft develops into an uncontrolled condition.

The setup, recognition and recovery must follow the applicable training and ACS procedures. During recovery, reducing the asymmetric thrust and lowering the angle of attack can restore directional control, followed by recovery to an appropriate safe airspeed and flight condition.

The FAA’s official multiengine chapter discusses VMC throughout its treatment of engine-out aerodynamics and emphasizes understanding the difference between minimum control and best single-engine performance.

Single-Engine Approach and Landing

Engine-out operation does not end once the aircraft is stabilized in cruise. The pilot must also demonstrate the ability to plan and execute a safe approach while managing reduced performance.

A single-engine approach requires careful energy management because landing gear and flap extension increase drag. The applicant should understand when to configure the aircraft, what speeds to maintain, how to manage asymmetric thrust, and whether a single-engine missed approach is realistically available under the conditions.

Smooth control becomes especially important close to the ground. Abrupt power changes, excessive bank, skidding turns, or allowing airspeed to decay can unnecessarily reduce the available safety margin.

Instrument Work When Applicable

When instrument privileges are involved, multi-engine testing can include instrument operations with one engine inoperative as specified by the applicable ACS.

This adds another workload layer because the pilot must maintain instrument accuracy while simultaneously managing asymmetric thrust, reduced performance, configuration, navigation, communications and approach procedures.

The challenge demonstrates why successful multi-engine flying depends on workload management as much as physical aircraft control.

What the Examiner Is Really Evaluating

It is easy to approach a checkride as a collection of individual maneuvers, but the ACS framework integrates knowledge, risk management and flight proficiency.

That means a technically accurate maneuver can still reveal weak decision-making. Likewise, an applicant who immediately recognizes an unsafe situation, takes appropriate corrective action and demonstrates sound judgment is showing exactly the type of risk-management capability the standards are intended to evaluate.

The examiner is continually assessing whether the applicant remains ahead of the airplane.

Does the pilot recognize deteriorating airspeed before it becomes critical? Does the pilot verify the failed engine rather than rushing? Does the pilot understand when additional power helps and when it increases asymmetric-control problems? Can the applicant explain why a particular action is appropriate rather than merely repeating a memorized procedure?

Those distinctions separate procedural memorization from genuine multi-engine proficiency.

Why Pilots Fail the Multi-Engine Checkride

Many unsuccessful Multi-Engine Checkride attempts are not caused by an inability to perform ordinary takeoffs, turns or landings. Problems often appear when knowledge, aircraft control and decision-making must be combined.

Common weak areas include:

  • memorizing VMC without understanding the factors affecting it;
  • misunderstanding single-engine performance;
  • allowing airspeed to deteriorate during an engine-out scenario;
  • rushing the identification and verification process;
  • confusing the failed and operating engines;
  • weak knowledge of aircraft-specific systems;
  • improper checklist discipline;
  • poor drag or configuration management;
  • becoming fixated on troubleshooting instead of flying;
  • failing to recognize when the aircraft cannot maintain altitude;
  • weak knowledge of limitations or performance charts.

The solution is not simply performing more repetitions of the same maneuver. Effective preparation requires understanding why the aircraft behaves as it does.

How to Prepare for the Multi-Engine Checkride

Preparation should begin with the applicable FAA ACS because it defines the standards against which the applicant will actually be evaluated. From there, pilots should know the POH or AFM for the specific airplane, understand its systems and limitations, and be able to calculate realistic performance for the conditions expected on checkride day.

The FAA’s Airplane Flying Handbook is another valuable source because Chapter 13 is devoted specifically to transition into multiengine airplanes and covers systems, performance, VMC, VYSE, engine failures and normal operations.

Rather than memorizing isolated answers, applicants should practice explaining scenarios. Ask what would happen after an engine failure at maximum weight on a hot day, how a windmilling propeller changes performance, why directional control deteriorates near VMC, or how an alternator failure changes the electrical plan.

If you can explain the airplane clearly and then demonstrate those principles safely in flight, the checkride becomes much more predictable.

Conclusion

The Multi-Engine Checkride is ultimately a test of whether a pilot can safely manage the additional capability and complexity that comes with operating a twin-engine aircraft. The examiner is looking beyond normal aircraft handling to determine whether the applicant understands asymmetric thrust, VMC, single-engine performance, aircraft systems, emergency procedures and the decisions required when available performance suddenly changes.

Strong preparation therefore combines three elements: knowing the applicable ACS, knowing the specific aircraft, and understanding the aerodynamics behind the procedures. Memorizing the red line, blue line, critical engine and emergency checklist is useful, but genuine proficiency means understanding why those concepts matter and applying them correctly under workload.
