5 Steps How to Prep for Your Multi-Engine Add-On and Ace the Checkride (Easy Guide for Pilots)

Getting your multi-engine add-on is a massive milestone. For most career-track aviators, it’s the bridge between being a "private pilot" and becoming a professional. But the checkride isn't just a formality. It’s a fast-paced evaluation of your ability to manage high-workload environments and keep a complex machine under control when things go south.

At Ace Pilot Academy, we see a lot of pilots come through our multi-engine flight training programs. The ones who ace the checkride on the first attempt aren't necessarily the ones with the most natural "stick and rudder" skill: they’re the ones who are the most prepared.

If you’re part of our Multi-Engine Mastery Week, you’ve already seen our breakdown of V-speeds and our deep dive into the PA-30 Twin Comanche. Now, it’s time to put it all together. Here is your five-step guide to prepping for and passing your multi-engine add-on checkride.

1. The ACS is Your Playbook

The FAA Airman Certification Standards (ACS) is not a suggestion; it is the literal grading sheet the Designated Pilot Examiner (DPE) will use. If you haven't downloaded the most recent version of the Private or Commercial Multi-Engine ACS, do it now.

Know the "Satisfactory" Standards

The ACS outlines exactly how much altitude you can lose during a stall and how many degrees of heading you can deviate from during an engine failure.

• The Oral Exam: Review the "Knowledge" section for every task. You need to explain aerodynamics, systems, and performance data without hesitation.

• The Flight Test: Review the "Skills" section. These are the maneuvers you will perform. If the ACS says you need to maintain +/- 100 feet, don't settle for +/- 150 feet in practice.

Focus on the Multi-Engine Specifics

The checkride focuses heavily on Area of Operation X: Multi-engine Operations. This includes:

• Maneuvering with one engine inoperative (OEI).

• Vmc demonstrations.

• Engine failure during various phases of flight (takeoff, cruise, and approach).

2. Master Systems and "The Numbers"

A multi-engine aircraft is a different beast than a Cessna 172. You have twice the systems and twice the potential for things to break. To ace the oral, you need to know your aircraft’s Pilot Operating Handbook (POH) better than the DPE does.

The PA-30 Twin Comanche Advantage

If you’re training in our fleet, you’re likely flying the PA-30 Twin Comanche. It’s an incredible trainer because it handles honestly. However, you must know its specific systems:

• Fuel System: Understand cross-feed operations. Can you explain exactly how the fuel flows if you have a leak on the left wing?

• Electrical System: Know the alternator outputs and what happens if one side fails.

• Landing Gear: Know the manual extension procedure. The DPE will ask you to walk through this.

Know Your V-Speeds Cold

Yesterday, we covered V-speeds in detail, but for the checkride, you need them memorized and ready for instant recall.

• Vmc (Red Line): Minimum control speed.

• Vyse (Blue Line): Best rate of climb OEI.

• Vsse: Intentional one-engine inoperative speed.

If you hesitate on "Blue Line" speed when the examiner asks, it sets a bad tone for the rest of the ride.

3. Drill the "Engine Out" Flow Until It’s Muscle Memory

The core of the multi-engine checkride is how you handle an engine failure. You don't have time to look at a checklist while the airplane is yawing toward the dead engine. You need a flow.

Identify, Verify, Feather

Most instructors teach a variation of this flow. Practice it in the cockpit (on the ground) until you can do it with your eyes closed:

1. Maintain Control: Pitch for Blue Line (Vyse), use rudder to stop the yaw, and bank 2–3 degrees into the good engine.

2. Power Up: Mix, Props, Throttles: Full forward (usually).

3. Clean Up: Flaps up, Gear up.

4. Identify: "Dead foot, dead engine." If your left foot is doing nothing to keep the plane straight, the left engine is the one that failed.

5. Verify: Retard the throttle of the suspected dead engine. If nothing changes, you’ve identified the correct one.

6. Feather/Secure: Follow the POH for feathering the prop and shutting down the fuel and mags.

Don't Just Work the Checklist: Fly the Plane

A common mistake is "head-down" syndrome. While you're working the checklist, the plane is drifting off course or losing altitude. Always prioritize Aviate, Navigate, Communicate. Tell the DPE what you are doing. "I am identifying the left engine as failed. I am verifying by pulling the left throttle. No change in performance. I am now feathering the left prop."

4. Schedule a Mock Checkride

You don’t want the actual checkride to be the first time you’ve performed under pressure. At Ace Pilot Academy, we recommend all students do a full "Stage Check" or Mock Checkride with a different instructor than their primary one.

Why a Fresh Set of Eyes Matters

Your primary instructor might have become used to your small habits. A fresh instructor will look at you with the same critical eye as a DPE.

• The Oral: Have them grill you on the "COMBATS" acronym (factors affecting Vmc).

• The Flight: Have them "fail" an engine at the most inconvenient time: like right after gear retraction.

This builds the mental toughness required for the real deal. If you can handle an instructor trying to distract you, you can handle the DPE.

5. Perfect Your Paperwork

You can fail a checkride before you even engine start if your paperwork is a mess. DPEs are high-level professionals; they expect your logbooks and endorsements to reflect that.

Checklist for Day-Of:

• IACRA Application: Ensure it’s signed by your instructor and all hours match your logbook.

• Logbook Endorsements: Verify you have the 61.63(c) endorsement for an additional grade of certificate (if applicable).

• Aircraft Documents: Have the AROW (Airworthiness, Registration, Operating Handbook, Weight & Balance) ready.

• Maintenance Logs: You must be able to show the DPE that the aircraft is airworthy. Know where the 100-hour/Annual, Transponder, Pitot-Static, and ELT inspections are located in the logs.

Dress the Part

This is a professional evaluation. You don't need a tie, but looking like a professional pilot goes a long way in establishing "Pilot in Command" authority. It shows the DPE you take the responsibility of a multi-engine rating seriously.

Ace the Ride and Build Your Future

The multi-engine add-on is often the last "fun" rating before you start the grind of time building or regional airline training. Enjoy the process, but stay disciplined.

The key to acing the checkride is simple: Preparation eliminates panic. When you know your V-speeds, understand your systems, and have your engine-out flows dialed in, the checkride becomes just another flight in the Twin Comanche.
