Since this game has a component of education about flight, I figured it could another one about the actual the engineering inside the (air)crafts.

I tried to do this with FT, simulating virtual individual fuel tanks, hydraulic systems, bleed air, electrical power, all the systems related to the engines, basically. But it's still rather limited, you can't simulate specific failures like oil or fuel line leaks (You can set fuel tanks and engines on fire but that's about it). Something like this would probably eliminate the infinite power exploit from pistons and rotators.

Another idea on this topic would be jet turbines that you can tweak, kinda like SR2 but better, where you can change:
- Engine type (Turbine, piston in-line/radial)
- Fuel consumption;
- Engine temperature (heat damage too);
- Transmission length and articulation;
- Gearbox and clutches for wheels, propellers and fans;
- Dynamos and electric motors for power generation amd start-up;
- (Might add more ideas later)

All of these could be somewhat modular, like two turbines connected to a single shaft through a gearbox that transmits power to two contrarotating propellers. This would probably eliminate the issue where you need multiple engine to make one realistic engines, where engine consumption is way higher than it needs to be, where you build turbofan engines that make a piston engine sound (custom sounds would also be nice)
