Inside the Examiner's Mind: Navigating the ACS

The checkride is often viewed by flight students as a high-stakes interrogation, a mysterious hurdle where a Designated Pilot Examiner (DPE) holds the keys to a career. That framing misses the point. The checkride is a standardized evaluation built around the Airman Certification Standards (ACS). To prepare effectively, a pilot should understand how the ACS drives the entire event.

For those pursuing a professional career or seeking a multi engine rating, mastering the ACS is just as important as mastering the aircraft. When a pilot understands the standards in plain terms, the checkride becomes more predictable, more manageable, and easier to train for.

Start Here: Understand the ACS

The Airman Certification Standards are the foundation of the practical test. They define what the applicant must know, how risk must be managed, and how each maneuver or procedure must be performed.

For the applicant, that matters because the ACS sets the framework for the entire checkride. The examiner is evaluating performance against published standards, not personal preference. The test is not built on surprises. It is built on defined tasks, measurable tolerances, and scenario-based application.

That is why serious preparation starts with the ACS itself. A pilot who knows the standards can train with purpose, study with direction, and show up for the practical test with a clear picture of what will be evaluated.

The Airman Certification Standard (ACS): The Objective Yardstick

The Airman Certification Standard is the evolution of the Practical Test Standards (PTS). While the PTS focused heavily on "how well can you fly the maneuver," the ACS adds two critical layers: Knowledge and Risk Management.

Every task in the ACS is broken down into these three categories:

1. Knowledge: Can you explain the system, the regulation, or the aerodynamics?

2. Risk Management: Can you identify, assess, and mitigate the risks associated with this specific task?

3. Skill: Can you fly the maneuver within the specified tolerances (e.g., +/- 100 feet, +/- 10 degrees)?

For a multi engine rating, the ACS is particularly rigorous. Candidates are expected to manage engine failures, understand Vmc (Minimum Controllable Airspeed) aerodynamics, and demonstrate precise control during single-engine approaches. At Ace Pilot Academy, we emphasize that the ACS is your "open-book test." There are no secrets; if it is in the ACS, it can be tested. If it is not in the ACS, it cannot be used as a basis for failure.

The Plan of Action: The ACS in Sequence

Before the applicant arrives, the checkride is typically organized around a clear testing flow. The goal is simple: cover the required ACS tasks efficiently and logically.

That flow usually follows a scenario. The oral may track a cross-country plan, moving through weather, performance, systems, and decision-making. In the airplane, tasks are often grouped to reduce wasted time and keep the evaluation organized. When a pilot knows the ACS requirements for a multi-engine rating, the next step on the checkride is rarely a surprise. The sequence usually makes sense based on the current phase of flight, altitude, and training objective.

Evaluating Performance: Satisfactory vs. Unsatisfactory

One of the biggest sources of checkride stress is the fear that one small mistake will end the ride. The ACS gives a more useful way to think about that problem. The evaluation is based on safety, standards, and corrective action.

An examiner is looking for three main things:

1. Any action or lack of action by the applicant that requires corrective intervention by the examiner to maintain safe flight.

2. Consistently exceeding ACS tolerances.

3. Failure to apply proper corrective action when tolerances are exceeded.

Notice the word "consistently." A momentary excursion of 110 feet in a maneuver with a 100-foot tolerance is not an automatic failure if the pilot recognizes the deviation and immediately applies the correct input to return to the desired altitude. The DPE is looking for mastery and situational awareness, not robotic perfection. In the context of a multi engine rating, this is vital. If an engine "fails" and you momentarily drift off your heading while performing the "Identify, Verify, Feather" flow, the examiner is watching to see if you catch that drift and correct it promptly.

The Multi-Engine Rating Perspective

For career-track pilots, the multi-engine rating is a pivotal milestone. The evaluation focuses heavily on the "Critical Engine" and the pilot's ability to maintain control during asymmetric thrust conditions.

Under the ACS for multi-engine airplanes, the "Engine Failure During Takeoff Before Vmc" and "Engine Failure After Lift-Off" tasks are non-negotiable. The examiner is looking for a "dead leg, dead engine" response that is both swift and accurate. These maneuvers are conducted with safety as the priority and are often demonstrated or simulated in a way that preserves a margin for error.

Candidates should focus on the Multi-Engine Flight Training syllabus, which aligns directly with these standards. By the time the checkride comes, the ACS tolerances should feel like a generous cushion rather than a tight restriction.

Reducing Anxiety Through Preparation

Anxiety often stems from a lack of control. The weather cannot be controlled, and the assigned examiner cannot be controlled, but preparation can be controlled.

To prepare effectively:

• Read the ACS front to back: Do not just look at the skill tolerances. Read the "Knowledge" and "Risk Management" sections for every task.

• Train to the standard: During final lessons at Ace Pilot Academy, hold performance to a higher standard than the ACS. If the ACS allows +/- 100 feet, aim for +/- 50.

• Practice correction, not perfection: Small deviations matter less than recognizing them early and fixing them correctly.

When a pilot walks into the briefing room with a clear understanding of the ACS, the conversation changes. The checkride becomes a standards-based evaluation, not a guessing game.

The Oral Exam: A Professional Conversation

The oral portion of the practical test is where the tone is set. The examiner will typically use scenario-based questioning when possible. Instead of asking, "What is Vmc?" they might ask, "You are taking off from a high-density altitude airport and lose an engine shortly after gear retraction. How does the current temperature affect your control of the aircraft?"

This approach tests your ability to apply knowledge, which is the hallmark of a professional pilot. If you can speak confidently about the systems of your aircraft: information found in our Multi-Engine Training Series: you demonstrate to the examiner that you are ready for the responsibility of the certificate.

Final Thoughts: The Path Forward

The path to becoming a professional pilot is paved with checkrides. When the process is viewed through the lens of the ACS, much of the mystery disappears. The examiner is not looking for perfection. The examiner is looking for safe, competent performance that meets the published standard.

At Ace Pilot Academy, training stays anchored to those standards. Whether the goal is a private pilot certificate or a multi engine rating, the priority is the same: study the blueprint, practice the maneuvers, and show up ready to perform to the ACS.
