This forum thread highlights a gap that has quietly widened as flight schools modernize their training fleets faster than the study materials built to support them. A student roughly a month from a Private Pilot checkride, training exclusively in a 2023 Evektor Harmony equipped with a Garmin G3X primary flight/multi-function display and a G5 backup unit, is finding that the standard prep materials—King Schools courses, ASA test prep books, Sporty's ground school, even many CFI lesson plans—still default to six-pack analog instrumentation as the baseline. For a candidate who has never flown behind a vacuum-driven attitude indicator or a traditional VOR head, that mismatch creates real friction: understanding failure modes, cross-checking techniques, and even basic terminology (turn coordinator vs. GPS-derived turn rate, for example) is taught through an analog lens that doesn't map cleanly onto what the student actually operates.
This matters because glass cockpits are no longer a niche training environment; they are increasingly the norm at Part 141 schools and even many independent Part 61 operations, driven by fleet turnover to aircraft like the Cirrus SR20/22, Diamond DA40/DA42, and newer Cessna 172s with the G1000 NXi. The FAA's own Airman Certification Standards (ACS) for the Private Pilot certificate were revised specifically to be equipment-agnostic, requiring applicants to demonstrate proficiency with whatever avionics suite they trained in—meaning a DPE examining a Harmony pilot should be testing G3X/G5 system knowledge, not asking about vacuum pumps or gyroscopic precession errors that don't exist in that airplane. Garmin publishes pilot's guides and interactive courses for both the G3X Touch and G5 that are the most directly relevant study resources, and the FAA's Instrument Procedures Handbook and Advanced Avionics Handbook (FAA-H-8083-6) address glass cockpit systems, automation dependency, and integrated autopilot operations in a way generic PPL prep guides do not. CFIs increasingly recommend applicants build their own personalized study guide cross-referencing the ACS task list against their specific airplane's systems, rather than relying on materials written for a hypothetical steam-gauge Skyhawk.
The broader trend here reflects a pain point across all of aviation training, not just the PPL level: instructional content, checkride prep, and even some DPE oral exam habits lag behind the pace of avionics modernization. Airline and business jet pilots see an analogous version of this in initial and recurrent training, where legacy CRM and systems courseware sometimes fails to keep pace with new-generation flight decks (Garmin G3000/G5000, Honeywell Primus Epic, Collins Pro Line Fusion) and their automation logic, energy management cues, and failure annunciation philosophies. For instructors and DPEs, the lesson is that examining and teaching must be tailored to the actual aircraft and avionics suite in front of them, not a generic template. For students and working pilots alike, the takeaway is the same: primary source material—OEM pilot guides, FAA handbooks written for advanced avionics, and type-specific systems courses—will always outperform generalized prep products once the airplane deviates from the analog baseline those products were designed around. As flight training fleets continue shifting toward all-glass platforms, expect demand for updated, avionics-specific ACS-aligned study materials to grow, and expect schools and DPEs to increasingly need fluency in multiple avionics ecosystems rather than a single standardized panel.
