390 Electric Airplane Test Flight: Max Trescott Reviews the Bristell B23 Energic

General Aviation Podcast
Max Trescott interviews Dr. John Trowbridge, a seasoned 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 welcomes aviation columnist, aerobatic instructor, and DPE Dr. Catherine Cavagnaro to explore smarter ways to plan cross-country flights. The conversation is inspired by Catherine’s June 2025 AOPA article titled “The Benefits of Getting High,” which argues that pilots often default to lower cruising altitudes or direct GPS routes without considering efficiency or safety trade-offs.Catherine explains that pilots should dig into their aircraft’s POH (Pilot’s Operating Handbook) to find performance charts that highlight how altitude affects both time and fuel efficiency. For her Bonanza, she found that the highest true airspeed at 65% power occurred around 7,000 to 8,000 feet, but fuel efficiency kept improving all the way up to the service ceiling. Using a sample 650-NM trip, she shows that cruising at 12,000 feet—despite a longer climb—saved enough fuel to eliminate a fuel stop, making the total trip time shorter.
They discuss how terrain, restricted airspace, and drop zones make GPS direct routing risky or impractical, especially across mountain ranges. Catherine shares how Victor airways, often dismissed as outdated, still provide safer terrain routing and proximity to emergency airports.
Max adds real-world examples, including dangerous direct flights through the Sierra Nevada that ended in CFIT accidents. He outlines three major cross-country paths—northern, central (I-80 corridor), and southern—each with their own altitude and weather considerations. The two agree that pilots often forget how minor route deviations can vastly improve safety with negligible time penalties. Catherine uses a mathematical analogy involving railroad tracks expanding in the sun to illustrate how small vertical detours can stem from large lateral gains.
They also dive into the importance of using supplemental oxygen—not just at legally required altitudes but even as low as 9,000 feet. Catherine explains how oxygen concentrators work, how they eliminate the need for tank refills, and how much better she feels after using them on long flights. Max echoes the sentiment, comparing it to the dramatic improvement that came with noise-canceling headsets. Together, they underscore how improved oxygenation can enhance alertness, decision-making, and post-flight fatigue levels.
When it comes to safety, Catherine highlights the “5 Fs” checklist she uses for personal go/no-go decisions, emphasizing that fatigue is the hardest one to self-assess. She emphasizes building “outs” into every flight plan, from not booking hotels in advance to carrying backup airline tickets in case weather or fatigue prevent safe continuation. Max shares a similar experience of aborting a leg from Reno when he realized how exhausted he was just after takeoff.
They also cover inflight considerations like maneuvering speed and turbulence. Catherine explains that because true airspeed rises with altitude while calibrated airspeed (which affects structural stress) stays lower, flying higher can reduce aircraft stress during turbulence—provided pilots understand how those values relate.
Finally, they joke about snacks in the cockpit—Catherine once flew past the Grand Canyon while munching a chocolate croissant from a bread-baking class. The lighthearted close reinforces the theme: safe flying is not just about skill, but about preparation, flexibility, and a little indulgence to make the journey enjoyable.
For any pilot planning a summer trip—or just wanting to sharpen their cross-country thinking—this episode is a goldmine of practical tips, insightful math, and hard-won wisdom.

Max Trescott and Rob Mark launch the first episode of NTSB News Talk, diving into NTSB agency news, recent accidents and newly published NTSB reports to help pilots better understand accident causes and improve decision-making in the cockpit. Please help us improve the show by sending us your feedback here. To hear future episodes of NTSB News Talk, Follow or Subscribe to the show in your podcast app.
They begin with a surprising administrative shake-up: the unexplained termination of NTSB Vice Chairman Alvin Brown . Rob questions the lack of transparency, pointing out how an independent agency like the NTSB should not be subject to political scapegoating without clear justification. Max brings up that the NTSB is hiring .
Next, they turn to cockpit video recorders—a long-recommended safety item by the NTSB. While commercial pilots and unions resist them on privacy grounds, Max and Rob argue that video can play a vital role in understanding pilot behavior and causes of crashes, especially in general aviation where data is often limited. Rob references Matt Thurber’s editorial advocating for video recorders and highlights tools like CloudAhoy that already allow post-flight review.
The hosts then discuss several accidents. One involved a Cessna 207 in Alaska that crashed during a go-around, possibly due to a dog on the runway. They examine when it’s safer to land versus abort, and why go-around procedures—rarely practiced—are often poorly executed, even by experienced pilots.
Two Citabria crashes raise density altitude concerns. One near Big Creek, Idaho , ended with no survivors; the other, in Wyoming, occurred during a flight to spread ashes . A partial engine power loss, high terrain, and low climb capability proved fatal. Both hosts emphasize how critical it is for instructors to teach performance limitations in high-elevation operations, especially in underpowered aircraft.
Max talked about a Fireboss firefighting seaplane that ditched in the Atlantic, killing the pilot, while on a ferry flight to the Azores. He mentioned that experience ferry pilot Sarah Rovner talked in detail about ferry piloting issues in episode 379 of the Aviation News Talk podcast.
Another incident highlights poor weather decision-making. A Piper PA-28 crashed near Mount Equinox, Vermont after entering icing conditions in IMC. The non-instrument-rated pilot, traveling with family on a ski trip, stalled and crash-landed. The hosts explain how “get-there-itis” and poor weather avoidance can prove fatal, and caution against pressing on in marginal conditions—especially with passengers aboard.
The episode’s deep dive analyzes the fatal accident of N611VG, a Citation 560 over Virginia. The pilot lost cabin pressure at high altitude and became incapacitated due to insufficient supplemental oxygen. The aircraft, operating Part 91, had numerous maintenance discrepancies—including an empty oxygen bottle and neglected pressurization issues. The pilot and passengers perished. Rob emphasizes that maintenance negligence is a silent killer, and guests aboard privately owned aircraft may have no idea about their true safety risks.
Max and Rob conclude with a discussion on high-altitude emergency procedures, including explosive decompression response. They urge pilots to practice rapid descents to VMO and recognize the signs of hypoxia before it’s too late. Finally, they encourage all pilots—regardless of experience—to schedule a flight review with an instructor to refresh skills like go-arounds and emergency descents.
This debut episode delivers clear, actionable safety lessons and insider insight into real-world aviation accidents. It’s a must-listen for pilots, CFIs, aircraft owners, and anyone serious about flight safety and learning from the NTSB’s findings.

Max Trescott shares his top recommended settings for Garmin avionics systems, specifically the G1000, G1000 NXi, G3000, G5000, and the Cirrus Perspective and Perspective+ systems. These configuration tips enhance situational awareness, flight safety, and pilot efficiency—and many also apply to Garmin standalone navigators like the GTN 650 and 750.
The episode begins with a critical safety upgrade: switching the Traffic Page vectors from Absolute to Relative. Unlike absolute vectors (which only show heading), relative vectors display a target aircraft’s flight path in relation to your own—allowing you to detect potential collision courses earlier and take evasive action sooner.
Max also explains Pilot Profiles, which store individual settings for different pilots or flight types. These profiles auto-save any inflight changes, even if made by other users, which can unintentionally overwrite your setup. He offers a clever workaround: naming your profile something like “Maintenance Only” to discourage accidental use.
For Cirrus Perspective, Perspective+, and other G1000-based systems, Max outlines his strong preference for Track Up or Heading Up map orientations and why North Up is ergonomically flawed. North Up can disorient pilots in high-workload situations and may even contribute to midair conflicts, as it forces mental rotation of traffic and terrain. Airline pilots overwhelmingly avoid it—and you should too.
Other key settings include:
For Cirrus Perspective pilots, Max also emphasizes enabling Runway Extensions to help identify the extended centerline in complex or night conditions, and TFR overlays to stay compliant with airspace restrictions.
Soft key setup tips include:
Through these curated settings, Max demonstrates how pilots flying with Garmin or Cirrus Perspective avionics can custom-tailor their displays for clarity, efficiency, and most importantly—safety.

Dr. Victor Vogel, a former oncologist turned flight instructor, founded the nonprofit Susquehanna STEM to the Skies to improve STEM education in rural Pennsylvania. The aviation-based STEM program was launched to address declining science and math scores among students, especially after the COVID-19 pandemic. By combining aviation concepts with hands-on learning, the program offers a powerful way to teach science, technology, engineering, and mathematics in real-world contexts.
Victor discovered that aviation offers rich, practical applications for STEM—such as flight navigation, time-speed-distance calculations, weight and balance, and engineering challenges. At the heart of the program is a Redbird FMX full-motion flight simulator, which draws students to the airport and anchors immersive educational experiences. Victor quickly learned that involving educators—not just pilots—was critical. Today, the board includes school superintendents, career technical center (CTC) leaders, and drone experts.
Students experience aviation careers beyond piloting, including aircraft maintenance, drone operation, medical helicopter crews, and aerospace engineering. Field trips, Girl Scout and Boy Scout aviation badge events, career fairs, and summer STEM camps all expose kids to high-demand aviation-related fields. Programs often include time in the simulator, tours of LifeFlight helicopters, and visits to maintenance hangars and paint shops.
Partnering with Sun Technical Institute, the program offers career-track students opportunities to fabricate metal airplanes and build Mars rover kits. A Redbird J desktop simulator expands access for physically challenged students. Another initiative included building a pedal-powered Piper Cub with students, demonstrating how aviation and vocational trades can intersect creatively.
Several success stories highlight the program’s impact. One former flight attendant is now a multi-rated certified flight instructor after a single inspiring simulator session. Others have moved on to flight schools, the Air Force Academy, or regional airline careers. The program’s ripple effect is also reaching educators. One high school band director attended the AOPA High School STEM Symposium, launched an aviation club, and introduced aviation curriculum into his school.
The organization was incorporated as a 501(c)(3) in late 2020—just as the COVID-19 pandemic was surging. Despite the initial slow progress, Victor journaled his efforts during the pandemic, later publishing them in his book Pains and Planes, which captures both the struggle of cancer patients during COVID and his dream of launching a STEM nonprofit.
Looking forward, Victor emphasizes the importance of finding volunteers—especially retired pilots, mechanics, teachers, and educators. He believes many people are simply waiting to be asked to contribute. He encourages others to replicate this aviation nonprofit model in their own communities by starting with educators, partnering with local airports, forming a nonprofit, and reaching out to media for visibility.
For those inspired to launch a similar STEM and aviation program, Victor recommends building partnerships with school districts and intermediate units, seeking grants and donations, and always putting student engagement first. His program shows that aviation-based STEM education can uplift rural students and guide them toward rewarding careers.
