FAA Instrument Checkride Prep with an AI DPE

The FAA Instrument Rating practical test has two parts: an oral exam administered by the DPE and the flight portion. The oral typically runs one to three hours and is structured around the eight Areas of Operation defined in the FAA Instrument Rating ACS — Preflight Preparation, Preflight Procedures, Air Traffic Control Clearances, Flight by Reference to Instruments, Navigation Systems, Instrument Approach Procedures, Emergency Operations, and Post-Flight Procedures.

A DPE does not give you a list of questions to answer in order. Instead, they build a scenario — usually a complete IFR flight from one airport to another — and then probe your knowledge as the scenario unfolds. You will be expected to interpret weather, plan alternates, decode clearances, brief approaches, explain emergency procedures, and discuss regulations, all in context.

This scenario-based format is what makes the oral exam harder to prepare for than a simple written test. You cannot just memorize facts. You need to be fluent enough to apply regulations and procedures to novel situations under pressure. That fluency only comes from practice.

Many students spend most of their preparation time reading the Instrument Flying Handbook, reviewing the ACS, and watching YouTube videos. These are valuable resources, but they train recognition, not recall. A DPE is not asking you to identify a correct answer from four choices — they are asking you to explain your reasoning out loud, in the moment, in response to a follow-up question.

Active recall practice — actually talking through scenarios, being asked follow-up questions, and getting feedback on incomplete or incorrect answers — builds a different kind of readiness. It forces you to confront gaps you did not know you had, and it builds the confidence that comes from having already survived a tough oral exam.

MockDPE is designed to bridge this gap. The AI DPE does not accept a partial answer without a follow-up, just as a real DPE would not. If you say you would file an alternate but do not explain the alternate minimums criteria correctly, MockDPE will push back — which is exactly what your real DPE will do.

MockDPE starts each session with a complete scenario: an aircraft, a departure airport, a destination, current weather, and a planned route. Your AI DPE introduces the scenario and then begins the oral, asking questions that build on each other as the flight progresses.

Weather is pulled live from aviationweather.gov for your chosen airports. If you pick a scenario at an airport with actual low IFR conditions, your DPE will ask about those conditions. The alternates you need, the approaches available, and the currency requirements are all based on real data.

After your session, MockDPE gives you a per-area score breakdown aligned to the eight FAA Instrument ACS Areas of Operation. You can see where your answers were strong, where you needed prompting, and where you missed key points. That score map tells you exactly where to focus your remaining prep time.

MockDPE includes three DPE personas: Mike Thompson, a retired airline captain who is patient and conversational; Reece Barrett, an active DPE who is thorough and methodical and most closely mirrors a real checkride; and Robert Chen, who has a military background and examines strictly by the book.

Early in your prep, Reece Barrett is usually the best starting point because he most closely mirrors what a real DPE does. As your checkride date approaches, practicing against Robert Chen can make your actual exam feel comparatively relaxed — a deliberate confidence-building strategy.

If you know something about your actual DPE's style — from other students' gouge, for example — you can upload that gouge in MockDPE's premium tier and practice in a mode tailored to that examiner's known tendencies.

MockDPE works best as a complement to your ground study, not a replacement for it. A reasonable approach is to complete each ACS area in your Instrument Flying Handbook or study guide first, then run a focused MockDPE session on that area to test your understanding before moving to the next.

In the final two to three weeks before your checkride, switch to full mock checkride sessions to build stamina and cross-area fluency. The oral exam does not stay within one ACS area — a weather question can lead to a navigation question, which leads to a regulatory question — and full sessions simulate that flow.

Use the per-area scores from each session to guide where you spend your remaining study time. If you are consistently strong on regulations but weak on instrument approach procedures, that is where your hours should go.

Every MockDPE account starts with one limited mock checkride session at no cost, with no credit card required. This includes all three DPE personas, live weather, and ACS-aligned scoring — enough to give you a clear picture of the platform and where your knowledge stands.

Premium is $29/month or $249/year billed annually (saving $99 vs monthly). Premium unlocks unlimited mock checkrides, focused-area and focused-task practice, diagnostic assessments, instructor-style lessons, gouge upload, and the full progress dashboard across sessions.
