This episode of Behind the Prop takes a deep, practical look at aviation safety culture, pilot decision-making, and the human factors that continue to drive accidents across all experience levels. Bobby Doss and Wally Mulhern are joined by Paul Craig, author of The Killing Zone, to discuss why judgment—not just skill or legal minimums—is the foundation of safe flying.
The conversation begins with real-world examples of pilots choosing to delay or cancel flights despite external pressure, reinforcing that many of the best safety decisions never show up in accident statistics because nothing went wrong. Paul Craig shares data showing that from 2012 to 2023, approximately 82% of aviation accidents were survivable, shifting the focus toward preventing all accidents, not just fatal ones. Survivable accidents still represent breakdowns in judgment, awareness, or risk management, and often occur when pilots adopt an “it won’t happen to me” mindset.
A major theme of the episode is complacency, particularly as pilots gain experience. Wally and Bobby discuss how overconfidence can peak around key experience milestones, such as the first several hundred flight hours for pilots and around 1,000 hours for instructors. This complacency can quietly erode discipline in areas like preflight planning, fuel management, and risk assessment. The hosts emphasize that vigilance must be continuous, regardless of total time or aircraft type.
The discussion also explores the evolution of The Killing Zone and the decision to move its third edition to an aviation-focused publisher. The book’s continued relevance lies in its ability to wake pilots up to the statistically dangerous transition periods in their flying careers and encourage humility, preparation, and sound decision-making.
Throughout the episode, the group stresses the importance of practical understanding over memorization. Real safety comes from applying knowledge in dynamic, imperfect situations—whether navigating unusual airspace, managing fatigue, or making conservative go/no-go decisions. The episode closes with a strong reminder that aviation safety is a shared responsibility built through mentorship, education, and a commitment to putting life ahead of ego, schedule, or expectation.

This episode of Behind the Prop focuses on what truly determines student pilot readiness for solo flight, emphasizing judgment, consistency, and safety over simply meeting legal minimums. Bobby Doss and Wally Mulhern explain that solo readiness is not a checklist item but a mindset. Students must be willing to cancel a solo flight when conditions are not right, whether due to weather, aircraft condition, traffic volume, or personal readiness. The ability to say “no” is framed as a critical pilot skill, not a failure.
A major theme is the importance of consistent personal minimums. The hosts discuss how changing limits based on convenience or pressure can lead pilots into dangerous decision-making zones. Personal minimums may differ between pattern work and cross-country flying, but they must remain logically consistent and conservative. Clear boundaries, reinforced by instructors and aviation leaders, help prevent accidents caused by poor judgment and overconfidence.
The episode also stresses rigorous preflight inspections, especially on familiar aircraft. Complacency with aircraft condition is highlighted as a common risk, with reminders to physically verify fuel, oil, caps, and surfaces every time. Performance planning is equally important, as long runways and home airports can create a false sense of security. Understanding density altitude, weight, and engine performance builds confidence and prevents surprises during solo operations.
Traffic awareness and communication receive significant attention. In acknowledging crowded training environments, Bobby and Wally discuss how poor pattern discipline and weak radio calls contribute to near midair collisions. Students are encouraged to master pattern procedures, listen more than they talk, and fully understand both towered and non-towered operations before soloing.
Emergency preparedness rounds out the discussion. Pilots must be ready to handle unexpected failures alone by prioritizing aviate, navigate, and communicate. Practicing emergencies, memorizing light gun signals, and rehearsing radio failures help ensure calm, effective responses when things go wrong.
Finally, the hosts address training philosophy. Instructors are encouraged to reduce over-talking and create space for students to think independently. The goal is to produce pilots who take ownership of their decisions, demonstrate sound judgment, and fly safely—not just students who follow rules or pass checkrides.

In this episode of Behind the Prop, Bobby Doss and Wally Mulhern explore how pilot training can—and should—better integrate ground knowledge with real-world flying skills. Titled “From Ground to Sky: The Equal Journey,” the discussion challenges the long-standing separation between classroom learning and cockpit experience, arguing that true pilot proficiency comes from blending the two from the very beginning.
Wally shares insight from airline training at United, where modern programs no longer rely on weeks of traditional classroom ground school. Instead, pilots complete short, focused computer-based training at home and transition almost immediately into flight training devices. By learning systems, normal procedures, and abnormal scenarios while seated in the cockpit and actively manipulating switches, pilots gain a deeper, more durable understanding than rote memorization ever provides. This hands-on approach reduces disengagement and accelerates learning by tying knowledge directly to action.
Bobby contrasts this with common practices in general aviation, where students are often encouraged to “get ground school out of the way” before flying. He explains why this mindset is flawed, emphasizing that interacting with taxiway signs, runway markings, airspace, and procedures in real time creates understanding that flashcards and videos cannot. Ground knowledge, he argues, should be continuously reinforced throughout flight training—not treated as a one-time hurdle.
A major theme of the episode is navigating the overwhelming number of training resources available today. Both hosts stress that the “best” ground school is the one aligned with a student’s flight school and instructor syllabus. Using mismatched materials often creates confusion and slows progress, even if those alternatives are cheaper or more popular.
The conversation then shifts to the critical gap between passing a written exam and being ready for a checkride—or real-world flying. Wally shares checkride examples where applicants knew answers by memory but struggled to apply them in practical situations, particularly with weather minimums and airspace requirements. Bobby adds personal experiences where rote knowledge failed under real operational pressure, reinforcing the need for contextual learning.
The episode also addresses modern avionics training, clarifying misconceptions about navigation identification and encouraging pilots to properly use available technology, including visual identifiers and autopilots, as safety tools.
The takeaway is clear: great pilots are not just “good sticks.” They are aviators who seamlessly combine ground knowledge, judgment, and flying skill to make sound decisions in real-world conditions.

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. By documenting lessons learned, reassessing personal limits, and setting intentional goals, pilots can make the coming year safer, more rewarding, and more professionally fulfilling.

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.
