This forum post, drawn from the r/flying community, offers a firsthand account of a pilot preparing for the Instrument Rating Airplane (IRA) knowledge test using Sheppard Air, a widely used FAA written test prep provider known for its rote-memorization approach to the question banks. The poster describes a compressed study timeline—roughly four days at under four hours per day—and achieved a 90 on the exam, while acknowledging that procrastination and skipping a review pass on missed questions likely cost a few extra points. The account also highlights a common pain point for instrument students: VOR-related questions, which the poster crammed for but felt uncertain about, ultimately encountering only one such question on the actual test.
For working and aspiring pilots, this kind of testimonial matters because FAA knowledge tests remain a persistent bottleneck in the certification pipeline, particularly for career-track pilots moving through instrument, commercial, and ATP ratings under Part 61 or Part 141 programs. Airlines, flight schools, and Part 135 operators depend on a steady pipeline of instrument-rated pilots, and anything that streamlines or accelerates that process—without compromising actual competency—has downstream effects on staffing and training throughput. Sheppard Air and similar products (Gleim, King Schools, PrepWare) have long been debated within the CFI and DPE community for their test-bank memorization methodology versus true conceptual understanding of instrument procedures, navigation systems, and regulatory knowledge. The tension the poster implicitly raises—scoring well on paper while admittedly guessing on VOR theory—reflects a broader industry concern that written test scores don't always correlate with practical proficiency, which is why the oral portion of the checkride and ongoing IFR currency requirements exist as a check on rote test prep.
This also ties into a larger trend affecting flight training economics: time and cost pressure. With flight training costs rising and airlines under pressure to rebuild first officer and captain ranks post-pandemic, students are increasingly optimizing for speed to certificate rather than depth of study, particularly for the knowledge test component, which many view as a hurdle to clear quickly before moving to the more consequential flight and oral portions of the checkride. Aviation training providers, DPEs, and FSDOs have periodically flagged this pattern, and the FAA itself has occasionally reshuffled question banks or introduced Airman Certification Standards (ACS) reforms in part to reduce the effectiveness of straight memorization and push test prep back toward applied understanding.
For flight instructors, DPEs, and training department heads reading accounts like this, the takeaway isn't necessarily to discourage tools like Sheppard Air, which remain legal, effective, and widely endorsed—but to reinforce during ground and flight training that VOR navigation, radio procedures, and other foundational IFR concepts need to be understood operationally, not just answered correctly on a multiple-choice bank. As VOR infrastructure continues to shrink under the FAA's minimum operational network (MON) program, some might argue reduced emphasis on VOR questions is appropriate; but for now, IFR pilots still need working knowledge of conventional navaids for both checkride success and real-world contingency flying when GPS or WAAS systems are unavailable.
