    E184 - Pilot Resolutions for the New Year

    In this episode of Behind the Prop, Bobby Doss and Wally Mulhern reflect on the lessons learned from flying in 2025 and use those experiences to frame practical pilot resolutions for the year ahead. The conversation opens with an honest discussion about why there is no such thing as a perfect flight, even for pilots with tens of thousands of hours. From automation surprises in advanced aircraft to long, weather-impacted piston flights, Bobby and Wally share real examples that reinforce the importance of staying mentally engaged and maintaining strong manual flying skills. Bobby recounts earning his Vision Jet type rating and the humbling moments that followed, including approach errors caused by mode confusion and overreliance on automation. These experiences highlight how quickly situations can escalate when pilots assume the airplane will “fix it” for them. Wally adds his own “never again” lesson involving fuel planning, where chasing cheaper fuel led to delays, extra flying, and higher costs. Together, these stories underscore a core theme of the episode: reliability, preparation, and judgment matter more than convenience or marginal savings. The hosts dive into personal minimums and proficiency, challenging pilots to reevaluate their limits as skills, experience, and operating environments change. They discuss why flying IFR, especially in actual weather, is mentally fatiguing and why proficiency can erode quickly without regular practice. Wally uses sports analogies to explain the importance of gradually building confidence in real conditions, while Bobby emphasizes aligning personal minimums with terrain, weather, and familiarity—not just legal minimums or flight school standards. The episode also explores how pilots can elevate their skills by using instructors strategically and taking advantage of programs like FAA WINGS. Rather than viewing instructor time as a burden, Bobby and Wally encourage pilots to treat it as an opportunity to sharpen skills, gain confidence, and reduce the need for formal flight reviews. They close by offering goal-setting guidance for student pilots, advanced trainees, and aspiring airline pilots, urging each group to balance knowledge, hands-on flying, and giving back to the aviation community. This episode serves as a reminder that growth in aviation comes from reflection, humility, and commitment.

    E183 - The Silent Killer - Distractions

    In this episode of Behind the Prop, Bobby Doss and Wally Mulhern unpack one of the most persistent and underestimated threats in aviation: cockpit distraction. Drawing from both historical airline accidents and modern general aviation trends, they explore how small lapses in attention can escalate into major safety events. The hosts revisit the tragedies of Eastern Airlines Flight 401 and United Flight 173, where professional crews became so focused on minor gear-indicator issues that they stopped flying the airplane—proving that distraction, not mechanical failure, can be the true killer. With the NTSB attributing 15–20% of GA accidents to distraction, the need for proactive management has never been clearer. The conversation moves into the cockpit realities of today’s pilots, where heavy reliance on iPads, automation, and touchscreen avionics often leads to excessive head-down time. Bobby and Wally share recent examples from training flights where pilots missed radio calls, misprogrammed GPS units, or became task-saturated simply because tech drew their attention away from flying. They emphasize the importance of preparing devices and routes before takeoff, and using automation deliberately rather than reactively. A key takeaway is that pilots must be willing to self-identify errors, speak up immediately, and assume the mistake is theirs until proven otherwise—a mindset that dramatically improves safety margins. The episode also highlights the critical role of the sterile cockpit, with Bobby advocating its use below 2,500 feet in GA. The hosts explain how nonessential chatter during taxi, takeoff, or climb dilutes situational awareness and can overwhelm newer pilots. They encourage instructors to reduce excessive talking as students advance, creating the “intentional silence” needed for real concentration and independent decision-making. Finally, Bobby and Wally address a commonly misunderstood distraction: open doors during takeoff or initial climb. They explain why an open door is typically benign, why rejecting a takeoff is often riskier, and why pilots must train for these scenarios before facing them unexpectedly. The episode closes with a call to action—pilots should openly discuss distractions, log them, review them, and build habits that keep them anchored to the core principle of aviation: aviate, navigate, communicate.

With over 12,000 flight hours and nearly three decades of flying experience, Mark shares how his passion for engineering and aviation led to building products that offer twice the value for only 10–20% more cost, creating a winning formula for pilots who prioritize both performance and safety. His companies now have 47 new aviation products under development, each designed to make flying more efficient, safer, and more enjoyable. Beyond business, Mark opens up about his transformation from the thrill-seeking days of the “Flying Cowboys” to becoming a safety advocate focused on humility and honesty. He reflects on how earlier flying videos showcasing aggressive backcountry flying unintentionally encouraged risk-taking, and how experience — along with age and perspective — taught him the true meaning of responsible flying. Mark emphasizes that proficiency and preparation make the difference between danger and mastery, comparing backcountry flying to instrument flying: both can be safe or deadly, depending on skill and mindset. The discussion also explores the growing issue of negativity in online aviation communities, where misinformation and quick judgments often drown out real learning opportunities. Mark and the hosts discuss the need for empathy, understanding, and constructive dialogue among pilots. In response to the fear and stigma surrounding mistakes, Mark introduces his vision for a “Pilot Confessional” podcast, where aviators can anonymously share near-miss experiences and lessons learned — helping others avoid similar situations without fear of backlash or violation. In a heartfelt conclusion, Mark reveals how a near-death medical experience reshaped his outlook on life and aviation. No longer chasing records or recognition, he now prioritizes peace, longevity, and family. His message to the aviation community is clear: be honest about your skills, stay humble, and fly for the love of life — not the thrill of risk.

    E181 - Beyond the Check Ride - Building Real World Pilot Judgment

    In this episode of Behind the Prop, hosts Wally Mulhern and Bobby Doss dive into one of the most important and often overlooked stages of a pilot’s development — the period right after earning a Private Pilot Certificate, when decision-making truly begins. While training provides structure and supervision, real pilot-in-command judgment is built through solo experience, reflection, and continuous learning. Wally explains that many new pilots complete training with strong technical skills but little real-world decision-making experience. He compares flying to golf — once the fundamentals are learned, consistent, thoughtful application separates good pilots from great ones. Without the safety net of an instructor, new private pilots must learn to evaluate fuel, weather, and personal minimums on their own. Both hosts emphasize that certification is not the finish line but the starting point of lifelong learning. The conversation covers key tools like the PAVE acronym (Pilot, Aircraft, enVironment, External pressures), which provides a structured way to assess preflight risk. Wally and Bobby also stress the importance of mental rehearsals and “what if” scenario planning to strengthen decision-making during unexpected events. Through real stories — from leaving chocks in place to handling equipment failures — they illustrate how small mistakes can lead to valuable lessons when managed properly. Technology plays a major role in modern flying, but the hosts caution against overreliance on apps and automation. Errors in systems like ForeFlight can mislead pilots who fail to verify data manually. Proficiency, not just currency, is the foundation of safety. Pilots are urged to set personal minimums, fly regularly with instructors, and stay humble about their skill level, especially after certification. The episode closes with a powerful reminder: good judgment is learned through experience, reflection, and discipline. Wally and Bobby encourage pilots to embrace real-world flying, learn from others’ incidents, and view every flight as an opportunity to refine decision-making. Their shared vision promotes a culture of continuous learning and safety, helping pilots evolve from newly certified to truly competent and confident aviators.

    In this episode, Wally Mulhern and Bobby Doss take listeners deep into the mindset and methods behind effective flight planning. They break down how professional pilots think, plan, and prepare—long before the engine ever starts. Wally explains why smart flight planning begins weeks in advance, sometimes as early as 20 days before departure, especially for longer trips. He shares how to select fuel stops just beyond the halfway point—around 280 to 320 miles—to maintain both efficiency and mental endurance. Past experiences taught him that chasing cheaper fuel can backfire through delays and limited services, making reliability and safety worth the extra cost. Weather plays a defining role in every flight, and Wally emphasizes checking forecasts repeatedly—three weeks, two weeks, ten days, and again the night before. He outlines how to analyze broad surface charts, TAFs, and METARs to anticipate conditions, adjust routes, and account for winds that can change fuel burn by up to 20% in a Cessna 172. He also discusses planning around TFRs and keeping alternate airports ready, even when not required. Bobby builds on that foundation with his focus on cockpit organization and readiness. His night-before checklist includes verifying oil levels, charging devices, updating ForeFlight, and packing flight materials. These habits reduce stress, save time, and make each preflight smoother. Wally echoes this with his own structured airline routine—packing the night before, updating iPads, and keeping notes on the yoke for future pilots. Both stress that good organization directly impacts performance and safety, especially during check rides. Together, they underline a shared philosophy: prepare early, plan thoroughly, and stay flexible. Weather forecasts are only predictions, sound judgment and real-time decision-making matter most. Their combined airline and general aviation experience shows that professional-grade preparation leads to safer, more confident flying. Whether you’re a new student pilot or seasoned aviator, this episode delivers actionable insights on fuel management, weather interpretation, and cockpit discipline—helping you fly smarter, safer, and more like a pro.

    E177 - Mastering Energy Management for Approaches and Landings

    Mastering energy management is one of the cornerstones of becoming a safe and confident pilot. In this episode of Behind the Prop, Bobby Doss and Wally Mulhearn unpack the topic in detail, showing how altitude, airspeed, and power all work together as “energy assets” that must be carefully managed throughout every phase of flight—especially on approach and landing. Drawing from countless check rides, Wally describes how many applicants fall into the trap of treating every descent as a power-off glide, when in reality, a controlled descent with power and speed can be safer and more effective. Bobby shares his own learning curve, including stories of fast landings and bounced touchdowns, underscoring why setting up a stabilized approach is non-negotiable. Together, they walk through rules of thumb for descent planning, techniques for recognizing if you’re high or low on base, and how instrument training can help sharpen a pilot’s “sight picture” of a standard glide path. Listeners will hear practical guidance on the classic “pitch for airspeed, power for altitude” debate, and how those principles apply differently in cruise versus the landing phase. The duo also highlight the dangers of over-correction and porpoising, explaining why patience and small, measured inputs make all the difference. Wally’s mantra—“eyes moving fast, hands moving slow”—is a powerful takeaway for anyone working toward smoother, more confident landings. The episode wraps with recommended resources like the Airplane Flying Handbook, FAA Risk Management Handbook, and the AIM, plus encouragement to practice energy management on challenging days with an instructor. Whether you’re a new student preparing for a checkride or an experienced pilot refining your technique, this discussion offers the tools to better understand and master the flow of energy in your aircraft.
