polcat Posted July 21, 2014 Share Posted July 21, 2014 Yes, each engine has dual FADECs. However, only one is used at a time. The J has "power levers" instead of throttles without the need for condition levers. The beauty of the FADECs is that I can slam the power levers full forward, which we do for every takeoff, and never have to worry about over-temping or over-torqueing an engine. Re-synching the props and reduced power takeoffs are also not required in the J. Quote Link to comment Share on other sites More sharing options...
toepexs Posted July 22, 2014 Share Posted July 22, 2014 Any way what FADECs stand for ? Quote Link to comment Share on other sites More sharing options...
PerfManJ Posted July 22, 2014 Share Posted July 22, 2014 FADEC = Full-Authority Digital Engine Control Basically a computer that controls engine operation based on input from the throttle quadrant. As polcat explained, there is a single "power lever" for each engine. Re-synching the props and reduced power takeoffs are also not required in the J. The J could still benefit from reduced power takeoff, in terms of engine life. Unfortunately, all of the takeoff performance data is based on max power only.

pjvr99 Posted July 22, 2014 Share Posted July 22, 2014 More simply put, you don't control the engines. You make a suggestion, and if the FADEC agrees, it will respond accordingly Quote Link to comment Share on other sites More sharing options...
Dutch Posted July 22, 2014 Share Posted July 22, 2014 More simply put, you don't control the engines. You make a suggestion, and if the FADEC agrees, it will respond accordingly Look it up on Wikipedia. I don't think I would like it. Quote Link to comment Share on other sites More sharing options...
