The problem is, AH's Fw190A-8 has three groups of fuel tanks, which burns in the order of aux -> aft -> fwd. The fuel in the aux tank is not used for Erhoete Notleistung(hereafter "EN"). It has nothing to do with the activation of emergency power, and is simply used for flight, powering the engine.
Now, this presents a confusion. Just how does our AH Fw190s work?
Injection of the C3 grade fuel mounted in the aux tanks, IIRC, is supposed to be essentially identical to the MW50 in functionality, cooling the cylinders in exactly the same manner. Does this mean the Fw190A-8 will not use the fuel in the aux tanks for normal flight? What if the Fw190A-8 flies around at normal power, without engaging EN? Will it; a) burn aft and fwd tanks, and then the engine quits due to the lack of fuel? Or b) can the fuel in aux tanks be fed into the engine like fuel in the fwd/aft tanks and be used for powered flight?
If its the former a), then our Fw190A-8 and Fw190F-8, which uses aux tanks for powered flight has some problems and should be fixed. The aux fuel should not be burnt, but rather its weight must be present on the Fw190A-8 as a constant value, since AH is unlimited in WEP - since the aux tank fuels were used for emergency power, not flight.
However, if its the latter b), then its another damn confusion brewing in the alley. If the aux tank fuels were used for both flight and emergency power, then the aux tank should not be used for flight until both the fwd/aft fuels run dry, but whenever WEP is engaged on the 190 the fuel should burn... except... that would mean AH will start limiting WEP times.
What's even worse, is our Fw190A-5 is at 1.65ata, which has a 10 minute WEP time. In AH, this 10 minute time is a loose indicator of a plane equipped with a special injection/boost system for emergency power. This can be viewed as some indication that our 190A-5 is the more rare versions mounted with the same EN system as the later A-8s. Then why does our 190A-5 have only fwd and aft tanks, but no aux tanks? How's the weight problem in the aux tank handled with the 190A-5 then?
...
In any case, all of this confusion is essentially a remnant of the old AH1 when WEP systems were not modelled in separately, but rather in a generic, simplified form of boosting the engine.
IMO this calls for a yet another revamp on how the WEP system is handled in each planes. There is just so much confusion revolving around the WEP, and especially if the WEP problem is related to the modelling problem as per the case of the Fw190A-8 and its aux fuel tanks... IMO something must be done.
I think I'd better write a suggestion in the wishlist forums.
Perhaps HT has changed his mind since then.
