In an automobile engine, you can optionally upgrade your alternators like if you had a couple thousand watts worth of stereo in the back. The consequence is the magnetic feedback in the coils places a load on the engine, robbing power (just like your AC)
So my question is, does DCS model this effect, such that, if I need best possible speed out of my aircraft, turning off everything gives me just a little bit more, or is the electrical load on a modern aircraft so small compared to the thrust that this isn't really worth the time/money to model? Thanks.
