For over a decade, general aviation has been chasing one elusive goal: a true 100-octane unleaded avgas that works across the entire piston fleet. Swift Fuels CEO Chris D&#39;Acosta has been at the center of that effort since 2012, and in this episode, he lays out exactly where the industry stands, why the process has been so slow, and what&#39;s still ahead.If you fly a piston aircraft, this conversation matters to you.  D&#39;Acosta breaks down:✅ which portion of the fleet is already covered by Swift&#39;s STCs✅ what&#39;s holding up the high-performance engines✅ the real story behind the university valve-seat recession controversy✅ whether the industry will hit the FAA&#39;s 2030 deadline for eliminating leaded avgas. ⏱️CHAPTERS0:00 – Introduction: Chris D&#39;Acosta&#39;s Journey from Oil &amp; Gas to Swift Fuels CEO8:00 – Why Major Oil Companies Walked Away from the Unleaded AvGas Race12:44 – Swift&#39;s STC Numbers: 1,200 Engines, 1,600 Airframes, 55% of the Fleet Covered15:28 – Inside the FAA&#39;s Seven Test Engines and Swift&#39;s High-Performance Fleet Partners21:10 – STC vs. ASTM vs. PAFI: Untangling the Certification Alphabet Soup30:50 – Why Swift Chose the STC Path Over PAFI (Liability &amp; Control)36:42 – Could the Transition Require 150,000 Individual Sign-Offs?40:07 – Why the STC Covers Both Engine and Airframe44:37 – Drop-In Fuel or Engine Modifications?

Barry Schiff has 28,000 hours, 363 aircraft types, five world speed records, and a 34-year TWA career that ran from the Lockheed Constellation to glass-cockpit 767s, and he&#39;s still not done asking why airplanes are built the way they are.Along the way, Barry and Mike dig into the topics that matter most to working GA pilots and owners: why light-aircraft maintenance culture is stuck in the 1970s, the case for running engines well past TBO, the real danger window right after an annual inspection, the mechanic shortage threatening the future of personal aviation, and where autonomy and single-pilot cockpits are actually headed. If you fly, wrench, or write about airplanes, this one&#39;s for you. ⏱ Chapters0:38 Welcome to Aviation Masters &amp; introducing Barry Schiff2:55 Learning to fly at 14 and racing through every rating6:39 Flying the Constellation and the transition to jets at TWA13:43 Life outside the cockpit: roots in Santa Monica, flying GA alongside the airline career18:13 Teaching gliders in Hawaii24:23 The bucket list: U-2, Space Shuttle sim, and a near-miss carrier landing29:11 63 years writing for AOPA Pilot and predicting ADS-B decades early33:35 Podcasting, and why light-aircraft maintenance culture needs to modernize38:29 Engines, TBO, and why GA engines haven&#39;t caught up43:53 Favorite airplanes, world speed records, and the Aerostar/Bushmaster stories49:54 Safety: loss of control, dangerous Vx climbs, and an unreported unsafe checkride56:21 Simulator training and recreating the Sioux City DC-10 accident1:03:32 Operation Peace Flight: the historic Israel–Jordan crossing1:11:00 Retirement flight, aging pilots, and insurance-driven age discrimination1:19:20 The future of flight: autonomy, Skyryse, and single-pilot jets1:24:59 The mechanic shortage as an existential threat to GA1:33:41 Barry&#39;s books and getting the next generation into aircraft maintenance1:43:09 Aviation trivia: hangar, cockpit, socked in, and hijack1:47:14 The flight he&#39;d redo, closing thoughts, and sign-off 📚 Resources &amp; LinksBarry Schiff&#39;s official site &amp; books - <a href="https://www.barryschiff.com/index.html" rel="nofollow">https://www.barryschiff.com/index.html</a>Savvy Aviation - <a href="https://www.savvyaviation.com/" rel="nofollow">https://www.savvyaviation.com/</a> 📍 Subscribe to Aviation Masters for more long-form conversations with the people shaping the future of GA.

Physicist, chip designer, serial entrepreneur — and the man who spent 25 years making aviation cheaper.  Host Mike Bush sits down with John Torode, founder of Dynon Avionics and Vashon Aircraft, for a wide-ranging conversation that runs from vacuum-tube computers and the birth of the PC to the $2,200 glass panel that upended general aviation. Along the way: GPS jamming, the brutal economics of FAA certification, what AI is really doing to software, the end of Moore&#39;s Law, and why getting an engine built may be harder than designing the avionics. Two MIT/Dartmouth classmates of &#39;66, both born in 1944, compare notes on careers that ran startlingly in parallel — and on the cost problem that could decide whether the next generation ever gets to fly. ⏱ Chapters0:26 — Meet John Torode &amp; two parallel lives3:38 — MIT, physics &amp; collecting five degrees6:21 — Learning to fly on $300 a month8:10 — Vacuum tubes, the IBM 650 &amp; Minsky&#39;s AI prophecy15:36 — Designing chips, networks &amp; the Cypress years22:20 — Founding Dynon: the quest for affordable avionics24:19 — GPS is everywhere — and dangerously easy to jam34:17 — The $2,200 glass panel that broke the mold40:40 — Aviation&#39;s volume problem &amp; dying semiconductors42:11 — Going certified: the FAA, the STC &amp; DO-17848:22 — Will AI rewrite (and certify) the code?1:04:46 — From Apollo&#39;s computer to the end of Moore&#39;s Law1:20:07 — Buy today&#39;s avionics, not tomorrow&#39;s1:23:04 — Telemetry, the cloud &amp; &#34;there is no privacy&#34;1:30:19 — Vision Aircraft: building a plane and an engine1:40:13 — Closing: keeping aviation affordable for the next generation 📍 Subscribe to Aviation Masters for more long-form conversations with the people shaping the future of GA.
