Diamond D-Jet controlled full-authority digital engine control (FADEC) system. Various functions, such as engine startup and over-speed selection prevention, have been automated and are seamlessly performed by the FADEC system. For redundancy, the dual-channel FADEC system uses four independent electrical power sources in addition to battery backup. Diamond opted to adopt a centerline location for the engine, air for which is fed through inlets embedded into the wing roots. The central location of the engine places makes it close to the center of gravity of the D-JET, reducing pitch forces, however, there are some drawbacks to this approach, including elevated air losses
