Why can't the Bf 109 Fly inverted in this "simulation"

[JG7_X-Man]

So this maybe common knowledge to everyone else - but not to me. So let's re-harsh.

 

So I was flying the Bf 109 and tried something I read years ago and have done frequently (Since Microprose European Air War to 1C's IL-2): Which is to hang upside down at high G's to track a diving target. I guess Have never done this since I purchased this because to my surprise - my engine stuttered and shut off. Thinking that I had engine damage I flipped back upright and looks back to see if  was trailing smoke, but I wasn't. 

 

I was under the impression that this was common knowledge among everyone that knew anything about WW II aviation. 

 

...By the time of the Battle of Britain, the Me 109 that faced Fighter Command had one major advantage over its rivals. Its engine had a fuel injection system that allowed a constant fuel flow even in conditions of negative-g.

 

Question: Did the Luftwaffe  have separate fuel systems for Eastern vs Western aircraft?

The fuel injection in the engine is only one part of a fuel system. Fuel tanks, fuel pumps and oil distribution - they all will malfunction after prolonged inverted flight.

Fuel injection is not a magic pill. Engines will fail after prolonged inverted flight regardless of the fuel system type for the reasons Ehret stated. Negative G's (pushover) does not exactly equate to inverted flight neccessarilly.  Further, most inverted flight has some element of POSITIVE G (loop, roll etc). Direct injection is better than basic carbs for this but you still cant abuse it for long periods of time. Little concerned about why you went directly for the fan boys rant over science/engineering....................

I see - so it's a factor of confusing maneuvers. After further reading the Bf 109 couldn't sustain inverted flight for more than 10 secs, nor did any other fighter of the period.

Thanks for the explanation.

Copy that! Thanks

Ehh, such a provocative title, questioning value of the game, before quick research. After that enlightenment takes place. 

This happens so often.
