The Eight Checkride Mistakes That Are Costing Pilots Their Certificates

Most checkride failures aren’t caused by an inability to fly. According to Boldmethod, the most common reasons candidates don’t leave the examiner’s office with a new certificate come down to knowledge gaps, procedural habits, and pressure-induced errors - all of which are preventable once you know what to look for.

Why This Matters Before Your Next Practical Test

The Airman Certification Standards (ACS) - which has replaced the Practical Test Standards for most certificates and ratings - defines every task, knowledge element, and skill tolerance your examiner will use to evaluate you. Understanding exactly where candidates consistently fall short gives you a targeted prep checklist that goes well beyond maneuver practice.

Mistake 1: Sloppy Weight and Balance Work

Familiarity is the enemy here. Candidates have run hundreds of weight and balance problems during training, and that familiarity breeds carelessness when it counts. Examiners aren’t just checking whether the final number comes in under gross weight - they’re watching the process.

Are you referencing the actual aircraft’s Pilot’s Operating Handbook (POH), not a generic training example? Are you using the correct moment arms? Are you accounting for fuel burn during the planned flight? A technically correct answer arrived at sloppily can raise serious questions about your habits as pilot in command. Show your method. Reference the actual documents for the actual aircraft.

Mistake 2: Describing Aircraft Systems Without Understanding Them

The oral exam ends more checkrides than the flight portion does. The most consistent trap is knowing what a system does without being able to explain how it does it.

There’s a significant difference between stating that the pitot-static system provides inputs to the airspeed indicator, altimeter, and VSI - and being able to walk through the plumbing, describe the distinct symptoms of a blocked pitot tube versus a blocked static port, and explain the appropriate pilot response for each scenario. Examiners are trained to ask follow-up questions. They will find where your understanding gets shallow. Study systems until you can explain them out loud to someone who isn’t a pilot.

Mistake 3: Not Knowing the ACS Cold

The ACS is the document your examiner is holding while you fly. It contains every tolerance you’ll be held to: altitude within 100 feet, heading within 10 degrees, airspeed within 10 knots for most tasks. These are published pass-fail criteria, not guidelines.

Many candidates fly maneuvers throughout training without ever reading the document that defines what those maneuvers need to look like. Download the ACS for your specific certificate or rating, read it, and fly to its standards from the beginning of training - not the week before your ride. Tolerances also vary by certificate level: Private, Instrument, and Commercial standards are not interchangeable, so make sure you’re studying the right document for what you’re actually being tested on.

Mistake 4: Emergency Procedures That Aren’t Committed to Memory

Some procedures require immediate action before there’s time to locate a page. Engine fire on the ground. Engine failure after takeoff. If you’re reaching for the POH when the examiner pulls the throttle to idle on climbout, that’s a problem.

Most POHs explicitly distinguish between memory items and checklist items for this reason - and examiners know exactly what those memory items are. Beyond emergencies, aircraft limitations should be equally immediate: maneuvering speed (VA), never exceed speed (VNE), maximum flap extension speed (VFE), maximum demonstrated crosswind component. These numbers need to come instantly when asked. If you’re doing mental math to recall your VA, that’s a gap worth closing before your checkride.

Mistake 5: Performing Checklists Rather Than Using Them

There’s a meaningful operational difference between doing a checklist and using one. Doing a checklist means reciting memorized items while touching switches, with the printed checklist functioning as a prop. Using a checklist means reading each item, performing the action, verifying the result, and moving to the next.

Examiners watch your eyes and your hands. They can distinguish between cross-referencing an actual document and running a memorized flow while calling it a checklist. Flows have their place - particularly during high-workload phases of flight - but a flow should be followed by a challenge-and-response verification against the printed checklist. Don’t skip items because you’re confident they’re already done. Positive confirmation is what separates a professional scan from a habit pattern, and habit patterns break down under stress.

Mistake 6: Busting Tolerances Under Checkride Pressure

Knowing the tolerances is not the same as holding them while talking to an examiner, managing the aircraft, clearing the area, and handling injected scenarios simultaneously. If training was conducted to looser standards and only tightened in the weeks before the ride, the stress of the practical test may push performance back toward the actual baseline.

One area Boldmethod specifically calls out: airspeed in slow flight. Candidates frequently creep below target airspeed during configuration changes, particularly when simultaneously trying to hold altitude. The examiner is watching both needles at the same time. Have an honest conversation with your instructor - not about your best day, but about your average performance on a normal day. That’s where checkride numbers are going to come from.

Mistake 7: Letting One Error Cascade Into the Next

A single tolerance bust doesn’t automatically end a checkride. What does compound the problem is allowing that error to pull your attention backward while the next task is unfolding in front of you.

Examiners understand that practical tests are high-pressure environments. A single error, depending on its severity, is often survivable. What they’re evaluating is whether a candidate has the judgment to be a safe pilot in command - and part of that judgment is the ability to recognize a mistake, correct it, and refocus on the next task. Treat each task as a standalone event. One specific caution: don’t editorialize your own performance during the test. Statements like “that was terrible, I never do that” have directly contributed to discontinuations. Just fly the airplane.

Mistake 8: Failing to Exercise Command Authority

This is the most consequential item on the list, and it cuts across every other mistake above. From the moment the practical test begins, the candidate is the pilot in command - not the examiner. An FAA authorization to conduct tests does not confer PIC authority.

Acting as pilot in command means making the go/no-go call when weather looks marginal and explaining the reasoning - not asking the examiner what they think. It means picking an alternate airport, assessing options, making a decision, and briefing it. It means slowing down to complete a checklist even when traffic creates pressure, asking for clarification on a confusing ATC clearance, and not compromising on safety or procedure because someone in the right seat expressed impatience.

Examiners are specifically trained to test command authority by applying pressure. They may suggest a course of action that isn’t optimal. They may signal impatience. They’re watching to see whether a candidate will compromise. The answer they need to see is that you won’t. Pilot in command means owning the outcome - from the preflight to the shutdown.

What Happens If You Fail a Checkride

A discontinuation is not a career-ending event. It’s a precise diagnostic: it identifies exactly where to focus remedial training, with no ambiguity. Many pilots who have gone through a discontinuation and returned better prepared describe it as one of the most valuable training experiences of their career - a perspective that’s genuinely difficult to hold in the moment, but worth holding.

The examiner’s job is not to fail candidates. Their legal obligation is to ensure that the pilots they certify are safe to operate in the national airspace. Most examiners want to issue that certificate. They need to be certain it’s warranted.

Key Takeaways

• Most checkride failures stem from knowledge gaps and procedural habits, not an inability to fly the maneuvers
• The ACS is both your study guide and your examiner’s grading rubric - read it, know the tolerances, and fly to them from the first lesson
• The oral exam is high-risk territory: systems knowledge needs to cover mechanisms and failure modes, not just functions
• Memory items are non-negotiable - aircraft limitations and emergency procedures must be instant recall, not calculated under pressure
• Command authority is evaluated throughout the entire test - act as pilot in command from the preflight briefing to engine shutdown, and don’t let examiner pressure change your decisions
