An AI DPE You Can Practice With Anytime

An FAA Designated Pilot Examiner is an FAA-authorized private citizen — typically an experienced pilot or CFI — who administers FAA practical tests on behalf of the FAA. For the Instrument Rating, the DPE conducts both the oral exam and the flight test, evaluates the applicant against the FAA Instrument Rating ACS, and issues temporary airman certificates on the spot for passing applicants.

The oral exam portion is entirely up to the DPE's judgment within the ACS framework. Some DPEs follow the ACS methodically. Others build a scenario and free-form from there. Most fall somewhere between these approaches — they have a flight scenario in mind and let the conversation evolve based on how the applicant responds. Understanding this format is essential for effective preparation.

Because DPEs are individuals with their own styles, preferences, and emphasis areas, practice with different examination styles — from patient to strict — is more effective than optimizing for a single approach. That is why MockDPE includes three distinct personas.

MockDPE's AI DPE starts each session with a complete scenario introduction, just as a real DPE does. You know the aircraft, the route, the weather, and the planned destination before the questioning begins. The DPE then works through the oral exam areas in a scenario context — the same flow a real DPE uses.

The follow-up question mechanism is the most important replication element. A real DPE does not move on when an answer is incomplete — they probe until they are satisfied. MockDPE does the same. If you mention that you need an alternate but do not explain the alternate minimums criteria correctly, the AI DPE will follow up. This is the single most effective way to surface knowledge gaps before the real test.

Regulatory citations are integrated into evaluations. When MockDPE notes that your answer was incomplete or incorrect, it references the relevant FAR or AIM section — the same citations a real DPE would expect you to be able to locate. You build familiarity with the regulatory framework over the course of multiple sessions.

The choice of DPE persona should evolve as your checkride date approaches. Early in your preparation, Mike Thompson (patient, conversational) is a good starting point. His style gives you room to think through answers and builds confidence as you learn the scenario-based format without excessive pressure.

Once you are comfortable with the format, switch to Reece Barrett (thorough, methodical). He most closely mirrors what most students experience in a real checkride — not harsh, but not lenient, and consistent in following up on anything incomplete. Running most of your preparatory sessions against Reece is the best baseline for checkride readiness.

In the final week before your checkride, sessions against Robert Chen (strict, by-the-book) can make your actual DPE feel comparatively relaxed. This is a deliberate calibration strategy — not because most real DPEs are as strict as Robert, but because arriving with the confidence that comes from having faced a harder examiner is genuinely useful.

One of the most valuable preparation strategies in the instrument community is reading gouge from other students who have tested with your specific DPE. Gouge describes the examiner's style, preferred topics, scenario types, and the areas they probe most deeply. This information is widely shared in pilot communities and on forums.

MockDPE's gouge upload feature (Premium) lets you put this information to direct use. Upload your gouge and MockDPE incorporates it into the session, weighting questions toward the topics your DPE is known to emphasize. This is not a guarantee that your real checkride will exactly match — DPEs adapt to applicants — but it significantly increases the specificity of your practice.

If you do not have gouge from your specific DPE, practicing against Reece Barrett is the most realistic general baseline. If you have partial information — for example, that your DPE strongly emphasizes weather — you can use MockDPE's focused-area practice mode to drill weather scenarios intensively.

Every MockDPE account gets one limited mock checkride session at no cost, no credit card required. This includes all three DPE personas, live aviation weather, and per-area ACS scoring. You can experience the full format and see your ACS baseline before committing to a subscription.

Premium is $29/month, or $249/year billed annually (saving $99 vs monthly). Premium unlocks unlimited sessions, focused-area and focused-task practice, diagnostic assessments, instructor-style lessons, gouge upload, and the cross-session progress dashboard. For students within a few weeks of their checkride, this is typically the highest-value study resource available.
