    E201 - The First Five Minutes

    Bobby Doss and Wally Mulhearn open the episode by celebrating the milestone of reaching 201 shows and reflecting on listener engagement from Oshkosh and beyond. The main topic focuses on the first five minutes of flight, the phase where workload spikes as pilots manage engine start, avionics, passengers, and clearances before taxi. They stress the importance of sterile cockpit discipline once the engine is running to prevent distractions that can lead to incidents like runway excursions. Wally shares his approach to control checks before engine start and using checklists as verification tools rather than to-do lists. The conversation covers common checkride mistakes such as incomplete taxi readbacks that omit the assigned runway and failing to anticipate instructions by listening to other traffic. During the taxi to run-up phase, they highlight situational awareness in congested areas like the delta ramp at Hooks Airport and the value of positioning to allow space for others. Bobby outlines his three-part mental model of setup, decision point at run-up, and final go/no-go assessment while advocating for finding reasons not to fly rather than reasons to proceed. The takeoff decision includes the fifty-seventy rule for aborting if rotation speed is not achieved halfway down the runway and personal flows like lights, clocks, and fuel. In the initial climb they stress completing the after-takeoff checklist promptly to avoid configuration issues such as forgotten flap retraction. The episode closes with a listener challenge to develop and test a personal first-five-minutes flow along with a candid confession from Wally about once departing with a rudder gust lock still installed.

    E200 - The Flight Before the Flight

    Bobby and Wally open the episode reflecting on recent experiences at Oshkosh, including social media feedback and a memorable interaction with a young aviation enthusiast whose parents are pilots. They then dive into the main topic of Episode 200, The Flight Before the Flight, stressing that most poor decisions occur during pre-flight preparation rather than in the air. The night-before sequence covers weather outlook briefings using multiple apps and 1-800-WX-BRIEF for human insight, verification of aircraft records especially for older experimental planes with modern avionics like G5 systems, fuel planning with extra margins beyond legal minimums, and self-assessment of fitness including illness or medication effects. On the morning of the flight they recommend re-evaluating forecasts against actual conditions observed outside and applying personal minimums that may differ by aircraft type such as the Saratoga versus a tailwheel. The hosts stress making these steps habitual through a simple card system and the PAVE checklist while inviting listener confessions about past decisions, shared personal minimums, and feedback on what they always check the night before. Wally adds insights from international flying on the importance of sleep management. They close by recommending the AOPA VFR personal minimums sheet and an ALPA Air Safety Institute case study called Fair Weather Flyer.

    E199 - The Dirty Dozen

    In this episode of Behind the Prop, hosts Bobby Doss and Wally Mulhearn dive into the Dirty Dozen, a set of twelve human factor traps that can affect pilots and mechanics alike. Originally released by the FAA around 2011 or 2012 as a poster for mechanics, these traps apply equally to pilots and can lead to serious situations if not recognized. The discussion covers everyday traps like complacency and distraction that bite on routine flights, as well as decision-making and awareness issues. Bobby and Wally share personal anecdotes, including stories about fuel checks during checkrides, the dangers of expectation bias, and real-world incidents like the Eastern Airlines Flight 401 crash caused by a distraction over a light bulb. They emphasize how these factors, including fatigue, pressure, lack of communication, and normalization of deviation, can cascade into problems for even experienced aviators. To combat these traps, the hosts offer practical defenses such as setting personal minimums, chair flying, using checklists effectively, and maintaining situational awareness. They stress the importance of being prepared, honest with oneself, and continuously learning to avoid the Swiss cheese model of accidents. Listeners are encouraged to review the Dirty Dozen poster linked in the show notes.

    E198 - True, False, or It Depends

    Bobby Doss and Wally Mulhearn return to the mics after a break to tackle aviation myths in this episode of Behind the Prop. They dive into common misconceptions heard in flight training, around the hangar, and during checkrides, using a true false or it depends format to separate fact from fiction. Topics range from accelerated programs and school environments to DPE interactions and real-world decision making. The hosts explore whether accelerated training is always faster, how weather impacts learning, and the fine line between confidence and overconfidence on checkrides. They discuss crosswind components, alternate airports, and why some statements like there is always another airport can be misleading. Personal stories from both hosts add depth to the conversation about what really makes a successful pilot. The episode wraps with a lightning round covering myths like twin engines being safer, taking the written exam first, chair flying, simulators, parachutes, controller attitudes toward students, and where learning actually happens. Bobby and Wally emphasize seeking wisdom over opinions and invite listeners to keep questioning and learning in aviation.

    E195 - Could You Handle an Emergency Tonight?

    Bobby and Wally kick off this episode by posing a tough question to all pilots: could you handle an emergency tonight? They stress that you don't rise to the occasion but fall to the level of your training, sharing examples of how complacency creeps in during checkrides and real flights. The hosts dive into memory items every pilot should know cold, like engine fire during start procedures, glide speeds, and oil pressure emergencies, while advocating for scenario-based training and chair flying to build reflexive habits. They explore real-world case studies, including a pilot in Australia who executed a calm gear-up landing after hours of troubleshooting and fuel burn-off. Wally recounts a medical emergency on a 737 where staying calm and breathing first made all the difference. The conversation turns to proactive strategies for night flying, such as following freeways, flying higher for more options, and using tools like ForeFlight's emergency glide mode to improve odds during engine failures or electrical issues. In the lightning round, they challenge listeners with scenarios like engine roughness at night over a city, comms failure into Class C airspace, and night VFR with lowering ceilings. The takeaway is clear: build habits through deliberate practice with instructors or solo, know your airplane's POH inside out, and prepare your brain for the day you hope never comes so you can fly safely and confidently anytime.
