  1. FADEC & the CFI New regulatory guidance CFI Workshop Bob Jex, ASI, North Florida FSDO

  2. Overview • Explanation of term “FADEC” • New regulatory guidance: Notice N 8000.331 • New definition of “Complex” Airplane! • Multi-Engine piston aircraft with FADEC • Practical Tests: Single-Engine ops • Your Questions

  3. What is “FADEC”? F – Full A – Authority D – Digital E – Engine C – Control In other words: Computerized engine control!

  4. FAA Notice N 8000.331 • New regulatory guidance, eff. Nov 2006 • Redefines “Complex Airplane” two ways • If FADEC installed: Retractable Landing Gear + Flaps + FADEC =Complex Airplane! • If FADEC not installed: • Use conventional definition! • Most significance for light piston twins

  5. New Piston Twin with FADEC • Diamond Aircraft DA42 “Twin Star” • TAA • Diesel engines (typ) • LE critical! • FADEC • G1000 Avionics • Carbon fiber • Training role Mfr. website: www.diamondaircraft.com

  6. DA42 trivia: • Chandelles, Lazy-8’s approved! • FSDO does not recommend these maneuvers. • Grass runways approved! • “Dynamic” stalls not approved • Vlo (extension & extended) = Vne = 194 • Powerplant instrumentation: • Percent load, 0 – 100% and • RPM • Loss of electrical power to FADEC unit(s) • Again:Critical Left engine!

  7. DA42 “Twin Star” Cockpit Engine M. Sw’s

  8. Practical Tests: Single-engine ops in FADEC piston twins

  9. FADEC Single-engine operations • Troubleshooting steps are minimal • Fewer things to check: focus is back on flying • ECU doing most of the work. New Term: “ECU Swap” • Autofeather provision • Zero-Thrust settings • Not published (yet) for DA42

  10. Intentional feathering • Retard thrust • Eng M. Sw. Off Prop feathers! • Restart: • Reverse steps! • Diesels use compression for ignition!
