This episode originally ran on the Aviation News Talk podcast. In it, Max Trescott interviews Dr. John Trowbridge, a physician and former senior Aviation Medical Examiner, to tackle a hidden yet critical safety topic: how over-the-counter (OTC) and prescription medications contribute to general aviation accidents. Studies have found that up to 40% of fatal accidents involve pilots with impairing substances in their system—ranging from allergy medications to sleep aids to alcohol. The problem? Many of these substances are legal and even commonplace, yet can significantly degrade judgment, memory, attention, and coordination.
Dr. Trowbridge emphasizes that many pilots—and even their doctors—are unaware of FAA wait-time guidelines. He explains the FAA’s “5x rule,” which states that a pilot must wait five times the recommended dosage interval before flying. So if a medication is taken every six hours, the pilot should wait 30 hours after the last dose. For 24-hour medications like Zyrtec, the wait time stretches to five full days.
The discussion highlights the particular dangers of first-generation antihistamines like Benadryl (diphenhydramine), which are highly sedating and frequently found in sleep aids like Tylenol PM, NyQuil, and Unisom. These medications, even when taken the night before, can impair cognitive function well into the next day. Alarmingly, Benadryl is the most commonly detected OTC drug in fatal GA accidents.
Dr. Trowbridge also warns about second-generation antihistamines like Zyrtec and Xyzal. While marketed as “non-drowsy,” these can still cause subtle sedation, especially in combination with alcohol or other medications. Alternatives like Allegra and Claritin are usually safer and FAA-approved—but only after personal ground-testing and AME consultation.
Beyond antihistamines, they explore other drug categories. For pain relief, medications like aspirin, Tylenol, ibuprofen, and Aleve are generally safe, but anything with “PM” on the label likely contains sedating ingredients. Prescription painkillers like codeine are outright disqualifying. Dr. Trowbridge shares unconventional options too, like topical lidocaine, coconut oil, and even horse liniment—though with cautions about application and legality.
Sleep aids are another minefield. Melatonin is the only one on the FAA’s “go list,” and even it should be ground-tested first. Nasal decongestants such as Afrin and Sudafed can raise blood pressure and cause jitteriness, making natural remedies like saline rinses or cool vapor inhalation preferable.
Cough medications also pose risks. Products with dextromethorphan (like DayQuil or Delsym) can sedate, as can multi-symptom formulas marked “PM” or “nighttime.” Gastrointestinal issues are more straightforward: most antacids like Tums and Maalox are safe, but anti-diarrheals like Imodium are not, due to sedation risks. UTIs are covered with non-sedating options like AZO and D-Mannose, but Dr. Trowbridge cautions pilots never to fly if symptomatic or on unfamiliar antibiotics.
The conversation then turns to alcohol. The FAA’s limit is 0.04%, but even lower levels can impair judgment, night vision, and reaction time—especially when combined with other medications or altitude-related hypoxia. Max cites an older FAA study showing that alcohol above 0.04% was found in 7% of fatal pilot crashes, with 3% involving both alcohol and drugs.
Finally, Dr. Trowbridge emphasizes the importance of pilot self-awareness and due diligence. Most doctors are not trained in FAA regulations and may prescribe disqualifying medications unless reminded. He urges pilots to always research their medications, consult their AME, and even speak with pharmacists about interactions and cognitive side effects.
Dr. Trowbridge’s website, ClearedForTakeoff.info, offers in-depth presentations on pilot health concerns like sleep, sinus issues, inflammation, and safe alternatives to disqualifying drugs. His goal is to help pilots avoid both illness and medication risks, empowering them to stay flying—and stay safe.

Max Trescott is joined by DPE Matt Johnson for a comprehensive and engaging mock oral checkride focused on the private helicopter pilot certification. This episode, one of the most popular styles in the Rotary Wing Show and Aviation News Talk history, simulates the real-world experience of sitting for an FAA practical test, complete with detailed discussions of eligibility, regulations, systems knowledge, and scenario-based questions.
Matt begins by describing his pre-checkride procedures, including document verification, aircraft records review, and setting a comfortable environment for the applicant. He emphasizes the three-legged stool concept: the examiner must be qualified, the aircraft must be airworthy, and the applicant must meet all regulatory requirements. To build rapport, Matt asks Max who his first passenger would be, which Matt then cleverly weaves into multiple checkride scenarios.
The mock oral kicks off with pilot certification and recency requirements under FAR 61.57, followed by an in-depth discussion of Robinson-specific endorsements under SFAR 73. Max correctly explains the need for an additional PIC endorsement after passing the checkride and describes the required flight reviews based on time-in-type.
The two then explore aircraft documents using the AROW mnemonic and systems such as weight and balance. Max demonstrates knowledge of performance planning, Vne adjustments, retreating blade stall, and preflight procedures. He uses both the PAVE and I'M SAFE checklists to explain how he assesses his personal readiness before a flight.
Matt tests Max's cross-country planning, asking about checkpoint selection, altitude choice, and airspace compliance. Max describes navigating around Hayward, California, and into the Central Valley, carefully avoiding Class B and C airspace. The discussion extends into weather analysis, interpretation of AIRMETs and SIGMETs, and use of EFB tools for inflight awareness.
In the systems and emergencies portion, Max explains operation of the electrical system, what to do in case of alternator or battery failure, and how the engine continues to operate using magnetos. They also dive into clutch actuator warnings, rotor system dynamics (free-teetering under-slung system), and the hazards of low-G mast bumping, vortex ring state, and forward CG conditions.
For add-on ratings, Matt details how the helicopter ACS matrix minimizes the oral scope for already-rated pilots. They compare traffic pattern procedures for helicopters versus airplanes, discuss airport lighting for heliports, and reinforce unique requirements like helipad rotating beacon colors (green-yellow-white).
Throughout the oral, Matt guides the conversation in a scenario-based manner to simulate a real checkride. He weaves in questions on regulations, performance charts, and even cross-references student answers to determine when to revisit topics like weight and balance, systems, or weather.
The episode wraps just before the preflight inspection begins, with Matt outlining the structure of the flight portion, which would include autorotations, hover maneuvers, and a post-flight debrief.
This detailed, realistic mock checkride offers exceptional value for both helicopter students and fixed-wing pilots considering a rotorcraft add-on. It brings listeners inside the mind of a DPE and prepares them for what to expect on test day—covering not just the “what” but the “why” behind FAA testing standards.
