3. Federal Aviation Administration 3 FADEC & the CFI May 5, 2007 What is “FADEC”? F – Full A – Authority D – Digital E – Engine C – Control In other words: Computerized engine control!

4. Federal Aviation Administration 4 FADEC & the CFI May 5, 2007 FAA Notice N 8000.331 New regulatory guidance, eff.

5. Federal Aviation Administration 5 FADEC & the CFI May 5, 2007 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. Federal Aviation Administration 6 FADEC & the CFI May 5, 2007 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!

New Term: “ECU Swap” –Autofeather provision Zero-Thrust settings –Not published (yet) for DA42

10. Federal Aviation Administration 10 FADEC & the CFI May 5, 2007 Intentional feathering Retard thrust Eng M. Sw. Off Prop feathers! Restart: –Reverse steps! –Diesels use compression for ignition!
