This forum post from r/flying represents a familiar ritual in the flight instructor community: a candidate preparing for the Certificated Flight Instructor-Glider (CFI-G) checkride crowdsourcing potential oral exam questions and examiner-specific insights ahead of their practical test. The poster is pursuing their first CFI certificate specifically in the glider category, and is soliciting both glider-specific stump questions and general CFI knowledge, while also asking for firsthand accounts of checkrides conducted by two named Designated Pilot Examiners (DPEs), Ron Ridenour and Sarah Arnold. While light on hard news content, this type of crowdsourced preparation thread is a long-standing and valuable tradition in aviation training culture, reflecting how pilots increasingly supplement formal ground school and DPE-specific reputational knowledge with peer-sourced, real-world exam experience shared through online communities.
For working CFIs and CFI candidates, this thread underscores a persistent reality of the FAA practical test system: outcomes and question emphasis can vary meaningfully by examiner, even within a standardized Airman Certification Standards (ACS) framework. Candidates routinely research individual DPEs' known focus areas, oral exam styles, and pass/fail tendencies before a checkride, and forums like r/flying, PilotWorkshops, and CFI-specific Facebook groups have become informal but influential repositories of this institutional knowledge. This is particularly pronounced in the glider community, which is smaller and more tightly networked than powered aviation, meaning DPEs are often well known by name and reputation to instructors nationwide, and specific examiner idiosyncrasies get discussed and passed down in far more granular detail than in larger power categories.
The glider CFI pathway itself is worth contextualizing for pilots outside that world. CFI-G certification requires deep command of aerodynamics unique to unpowered flight, energy management, thermal and ridge/wave soaring theory, aerotow and ground-launch procedures, emergency rope-break decision trees, and spin awareness training specific to gliders — much of which diverges meaningfully from the ACS content emphasized in the Airplane CFI initial. Glider instructors are also a comparatively scarce resource in the U.S. general aviation instructor population, and demand for qualified CFI-Gs has grown alongside renewed interest in soaring as an affordable, aerobatic-adjacent, and stick-and-rudder-focused entry point into aviation, as well as its use by some accelerated CFI-track programs and by pilots pursuing tailwheel/glider add-ons for insurance or skill-building purposes.
More broadly, this thread reflects a trend visible across all corners of professional and recreational aviation: the migration of institutional and tribal knowledge from traditional flight schools and mentor-mentee relationships onto public online forums, where crowdsourced checkride prep, DPE reviews, and study guides are increasingly treated as a normal and expected part of exam preparation. For airline and business jet pilots who came up through more conventional Part 141/61 power tracks, threads like this are a reminder that the instructor pipeline — particularly in specialty categories like gliders, seaplanes, and balloons — still depends heavily on a small number of experienced examiners and an even smaller community of instructors passing along know-how informally, a dynamic that has real implications for instructor supply, checkride consistency, and the long-term health of general aviation training capacity.
