Multi-Engine ACS Secrets Revealed: What DPEs Look For on Every Checkride

Meta Description: Get insider secrets for your Multi-Engine checkride from active Designated Pilot Examiner (DPE) Jeff Gerencser. Learn what examiners look for beyond the ACS and how to ace your rating.

Let’s be real for a second: stepping up to a multi-engine rating is one of the most exciting moments in a pilot’s career. You’re finally moving away from the single-engine trainers and into the world of "heavy" iron, well, heavier iron, anyway. But with that extra engine comes a whole new set of responsibilities, and frankly, a whole new level of scrutiny during your checkride.

As an active Designated Pilot Examiner (DPE) with over 30 years in the cockpit, I’ve sat in the right seat for hundreds of multi-engine checkrides. I’ve seen it all: the rockstars who could fly the plane in their sleep and the candidates who were technically "prepared" but lacked the mindset of a commercial multi-engine pilot.

The FAA Airman Certification Standard (ACS) is your roadmap, but it isn’t the destination. If you want to walk away from your checkride with a temporary certificate in hand, you need to understand what we, the examiners, are actually looking for when the pressure is on.

The "Hidden" Standard: Understanding the ACS Philosophy

Most students treat the ACS like a list of chores. "Keep altitude within 100 feet. Keep heading within 10 degrees. Don’t crash." While those metrics matter, the ACS is actually designed around Risk Management and Single-Pilot Resource Management (SRM).

When I’m evaluating you for a multi engine rating, I’m not just checking if you can hold a blue line. I’m looking at your decision-making process. Are you ahead of the airplane? Are you identifying risks before they become emergencies?

A common pitfall I see is candidates who can recite the V-speeds but have no idea how to apply them in a dynamic environment. The FAA wants to see that you aren’t just a "task manager," but a pilot who understands the why behind every procedure. During our accelerated flight training, we don't just teach you the maneuvers; we teach you the philosophy of the twin-engine aircraft.

The Engine-Out Flow: Precision Over Panic

The core of any multi-engine checkride is the One-Engine Inoperative (OEI) work. This is where most checkrides are won or lost.

In my experience as a DPE, the number one reason for failure isn't the actual engine failure: it’s the candidate’s reaction to it. I often see "the panic reach." This is when I simulate an engine failure and the student immediately starts grabbing levers without identifying which engine actually quit.

The "Dead Foot, Dead Engine" Rule

You’ve heard it a thousand times, but are you practicing it? When an engine fails, the airplane will yaw toward the dead engine. The foot you are using to push the rudder to keep the nose straight is your "live foot." The other foot: the one doing nothing: is your "dead foot."

DPE Secret: I am watching your feet. If I see you identifying the wrong engine and moving to feather the good one, the ride is effectively over. Slow down. Identify. Verify.

The "Verify" step is where many pilots stumble. You must smoothly retard the throttle of the suspected dead engine to ensure there is no change in aircraft performance before you take the irreversible step of feathering the prop. Precision beats speed every single time in a twin.

Mastering Vmc: The Aerodynamic Deep Dive

The Vmc demonstration is the "boogeyman" of the multi-engine checkride, but it doesn't have to be. As an examiner, I’m looking for your recognition of the loss of directional control.

Many applicants focus so hard on the airspeed indicator that they forget to look out the window. Vmc is an aerodynamic limit, not just a red line on the gauge. I want to see you recognize the onset: that moment where the rudder is floored and the nose starts to wander.

If you try to "fight" the airplane past its limit, you’re demonstrating a lack of understanding of multi-engine aerodynamics. A successful Vmc demo shows me that you respect the airplane’s limits and can recover promptly and correctly by reducing power on the operating engine and lowering the angle of attack.

Systems Knowledge: Drawing the Map

Let’s talk about the oral exam. This is where we determine if you have the technical authority to operate a complex machine. I don’t expect you to be a mechanic, but I do expect you to be an expert on your airplane.

One of my favorite "tests" is asking a candidate to draw the fuel system on a whiteboard. Can you show me where the crossfeed valves are? Do you know what happens to the fuel pumps when an engine fails? If you can't visualize how the systems interact, you can't troubleshoot them at 5,000 feet in the clouds.

Using resources like multi-engine checkride flashcards is a great way to drill this knowledge, but make sure you are applying it to the specific systems of the aircraft you are flying. We look for pilots who understand the consequences of system failures, not just those who have memorized the POH.

Scenario-Based Performance: The Real World

In the modern FAA checkride environment, everything is scenario-based. I’m not just going to tell you to "do a steep turn." I might tell you that we are maneuvering to avoid a bird strike or entering a holding pattern.

The biggest secret to impressing a DPE is treating the checkride like a real commercial flight. This means:

• Professionalism: Show up with your paperwork organized and your IACRA ready to go.
• Checklist Discipline: Use your checklists! Don't rely on memory for critical items.
• Verbalizing: Tell me what you are doing. If you are correcting for a crosswind or adjusting power, say it. It shows me you are actively managing the flight.

When you enroll in accelerated flight training, we immerse you in these scenarios so that by the time you sit across from me for the checkride, it feels like just another day at the office.

The Mindset of a Commercial Multi-Engine Pilot

At the end of the day, a multi-engine rating is a gateway to the airlines and corporate flight departments. When I sign that temporary certificate, I am saying that I trust you to fly my family in the back of that airplane.

We look for a "Checkride Ready" mindset. This isn't about being perfect; it’s about being safe, methodical, and authoritative. If you make a small mistake: and most people do: own it, correct it, and keep flying the airplane. The worst thing you can do is let one mistake snowball into a failure because you lost your focus.

Are You Ready to Ace Your Checkride?

Earning your multi-engine rating is a massive milestone. It requires a shift in how you think about flying, moving from "surviving" maneuvers to mastering the machine.

With over 30 years of experience and my perspective as an active DPE, I’ve designed our programs at Ace Pilot Academy to cut through the fluff and get you exactly what you need to succeed. We don't just help you pass; we help you become a pro pilot.

If you’re ready to stop "studying" and start learning how to fly twins with the precision the industry demands, it’s time to get started.
