If you move the propeller of a plane that has just stopped and the magnetos are on, it's very likely the engine might have some pistons firing. The choice of cleaning the explosion chambers depends also on the weather and temperature conditions.
Magneto switching is a very important part of the preflight checks, before take off you bring RPM well below idle and try running the engine on one magneto at a time, all you should get is a circa 100 RPM drop. If your engine quits with just one magneto off it means that the one that is on is faulty.
A dual magneto system is not meant to burn mixture better, it's a redundant system to have extra security.

Military procedure yes, and we're talking about a military flight sim.
Here's a nice read for you, dual ignition really is meant for a better burn in those big-bore engines. It even lessens the risk of engine knock!

yes, dead generator means dead systems. Game over.

That's not what I read in electrical schematics of aircraft.

the batteries used on aeroplanes were meant to operate at low temperatures.

Batteries warm up while charging, and during flight, they are continuously charged unless charging is shut off manually.

..then you don't want to fly in most WW2 planes or light sport aviation planes. If your generator fails your battery won't be able to run your systems for long. Most of the engine ancillaries like magnetoes and primary pumps (at least in WW2 planes and light aviation) are actually connected and powered by the engine by means of reduced gearings, but you will still need the generator to run other components (flaps, aux pumps, ligths, gunsight, some instruments, radio, some cooling systems etc..)

That's why I started the topic in the first place! The battery won't keep it for long is something else than immediately dead systems.

does wiki mention the fact that some systems that keep the engine running and performing adequately need electricity? You mentioned the FW190 kommandgerat which I think it's the perfect example.

Kommandogerät is one example, prop pitch governor on the P38 is another. The mags will work anyway and if the rest fails, you still have a chance to get home.
