The Reddit thread underscores a persistent point of confusion for instrument students working through the FAA's cross-country PIC time requirement under 14 CFR 61.65, which mandates 50 hours of cross-country time as pilot in command before the instrument checkride. The original poster raises a common misconception: the belief that safety-pilot arrangements, where two pilots split flight time by trading roles under a view-limiting device, can be used to build XC PIC time for both parties simultaneously. As the poster correctly discovers, only the pilot who is actually acting as PIC and meeting the cross-country definition (a landing more than 50 nautical miles from the original point of departure) can log that time toward the 61.65 XC requirement. The safety pilot, even though legally acting as PIC for the portion of the flight where the other pilot is under the hood, is not accumulating cross-country PIC time unless the flight itself independently satisfies the XC criteria for that pilot's own logbook entry and role-swap timing.
For working and prospective professional pilots, this distinction matters because logbook accuracy and regulatory compliance are foundational to a career built on trust and paper trails. Errors in interpreting XC time-building strategies can lead to disqualifying discoveries during an FAA knowledge test prep, checkride, or worse, during an airline or Part 135 background/records audit years later when a DPE or check airman scrutinizes early training logs. This is especially relevant given increased scrutiny industry-wide on logbook integrity following incidents of fraudulent time-building and record-keeping, including ATP-level investigations into falsified hours. Understanding the letter of 61.65, 61.1's cross-country definitions, and how they diverge from the simpler cross-country definitions used elsewhere in Part 61 (such as for commercial certification under 61.129, which has its own distance and route-structure nuances) is a rite of passage that every CFI should be reinforcing early, rather than letting students self-diagnose through trial, error, and Reddit crowdsourcing.
The economic calculus the poster raises, whether to split time now or fly solo, also reflects a broader reality of general aviation flight training: time-building is expensive, and efficiency matters enormously to students self-funding their path toward an instrument rating, commercial certificate, and eventually a professional flying job. Renting an aircraft solo for XC time versus splitting costs with a safety pilot changes both the calendar timeline and the total money spent, but as the poster intuits, splitting time only pays off if it serves a dual purpose, such as simultaneously building toward the safety pilot's own currency, instrument proficiency, or a different certificate's time requirements like commercial PIC XC hours under 61.129, which do allow more flexible logging arrangements in some scenarios. This is a case where flying more hours (74 versus 37) in exchange for shared cost isn't automatically the better deal unless total PIC time accumulation itself has value toward a later goal such as the 250 hours needed for a commercial certificate or building toward ATP minimums.
More broadly, this thread is emblematic of the information gaps that persist in part 61 flight training pipelines, where students frequently rely on informal peer networks, online forums, and word-of-mouth "hacks" rather than authoritative guidance from instructors or the FARs themselves. As the pilot shortage narrative shifts and flight schools scale up throughput to meet airline and regional hiring demand, ensuring CFIs are proactively teaching the nuances of loggable time, not just how to pass a checkride, remains essential to producing pilots who enter the profession with clean, defensible records. For students on the collegiate, Part 141, or self-funded 61 track alike, this kind of foundational regulatory literacy pays dividends well beyond the instrument rating, shaping habits around record-keeping and rule interpretation that carry into airline interviews, ATP-CTP eligibility, and Part 135 or 121 line operations where documentation errors carry far higher stakes.
