Learn it, retain it, and drill the scenarios a real DPE will actually ask. The free starter deck.

Engine-out aerodynamics, Vmc factors, and the single-engine decisions DPEs love to probe. Our deepest deck. Now also covers the half the oral opens with: airworthiness and inspections for an airplane with two of everything, inoperative equipment and ADs, fuel tank sequencing and imbalance, single-engine fuel reserves, known-icing approval, tailplane icing and boot myths, and the mission decisions a DPE wants mitigated, not just listed.

Approaches, regulations, weather, and IFR decision-making mapped to the Instrument ACS.

Commercial privileges, complex/high-performance, performance maneuvers, and 14 CFR 119/91 limits.

Fundamentals of instructing, the learning process, and teaching to the ACS like an instructor.

Teaching instrument flight: approaches, holds, IFR regs, and common student errors to correct.

Instructor-level multi-engine: teaching Vmc, engine-out, and the demonstrations an MEI must give.

Air transport knowledge: high-altitude ops, performance, and ATP-level regulations.

14 CFR Part 61 and Part 91 — currency, privileges, and the limits DPEs test.

Theory, products, and go/no-go judgment from the FAA weather handbooks.

Lift, load factor, stalls, and stability from PHAK Chapter 5.

Powerplant, electrical, pitot-static, and fuel — how it works and how it fails.

Density altitude, weight & balance, and reading AFM/POH charts correctly.

Pilotage, dead reckoning, VOR/GPS, and cruising-altitude rules.

Classes A–G, entry requirements, and reading the sectional.

ADM, PAVE, IMSAFE, and the human-factors traps that bust checkrides.

Engine failures, fires, electrical, and inadvertent IMC — fly the airplane first.

The highest-frequency oral questions across topics, framed the way DPEs ask them.

The #1 logbook confusion, taught the way a DPE explains it — when you may act as PIC, when you may log PIC, and when two pilots can both log it. Free.

Why cross-country time is never one bucket. General XC vs the >50 NM rating definition vs ATP — plus the long-XC requirements DPEs verify. Free.

Actual vs simulated, what a safety pilot logs, and exactly which approaches count toward instrument currency — the errors that quietly break recency. Free.

Three different definitions of "night," what counts as a night landing, and why touch-and-goes don't keep you night-current. The definitions DPEs love to probe. Free.

Every field, what it means, and a right vs wrong example — plus the column math (which totals are subsets and which must add up). What's legally required vs professional. Free.

For CFIs: which endorsement, what it requires, what wording, how long it's valid, and the mistakes DPEs catch — grounded in the current AC 61-65K. Free.

Know the glass like the oral tests it: PFD/MFD, reversionary mode, AHRS vs. air data, red-X failures, GPS/VLOC source, autopilot modes, and what you fly when it quits. Then the half nobody teaches: the AFM supplement is what actually authorizes the airplane, required and inoperative equipment in an integrated panel, the pitot-static failure that never shows a red X, autopilot limitations, Nearest in a real emergency, automation surprise, and the electrical failure in IMC that is a diversion decision, not a monitoring exercise. Cited to the Garmin Pilot's Guide and FAA handbooks — install-specific items marked per AFM/POH and the G1000 supplement.

The box in most training and rental panels. GPS vs. VLOC, what makes an installation IFR-legal, WAAS and LPV, advisory vertical guidance that is not a glideslope, sequencing and the missed approach, RAIM, and database currency — plus loading vs. activating, matching the box to the clearance, course reversals, departure procedures, autopilot mode awareness, and single-pilot IFR workload. Knowledge and decision level — install-specific items marked per AFM/POH and the avionics supplement.

Get drone-legal and stay there: airspace & LAANC, Remote ID, the four Subpart D over-people categories, night rules, waivers vs. authorizations, lost-link and battery decisions, loading and maintenance — and the traps that cost operators their certificates. FAA-cited. Free.

Read the chart, don't memorize the figure. Sectional symbology, approach plates, enroute charts, and Part 107 airspace — comprehension-first, ahead of the Oct 26, 2026 embedded-chart-image change. The printed testing supplement is NOT being withdrawn — the FAA has not set a removal date. FAA-cited. Free.

The rule changed and most study material didn't. What MOSAIC actually did to the light-sport definition and to sport pilot privileges — stall-speed limits, occupancy, night, and the simplified-flight-controls endorsement that applies at every certificate level. Plus the certification procedure half nobody teaches: practical test vs. proficiency check, the VH endorsement that survived when the speed limit didn't, gear and propeller endorsements, and what an endorsement from a sport-pilot-rated instructor actually does to the pilot who receives it. FAA-cited. Free.

The exact misconceptions and gotchas that produce notices of disapproval — and how to beat them.
