Sometimes we very eagerly discuss internally, which source is the best. Sometimes we even have to do reasonable estimations, if sources are impossible to get. We are normal people, we are 'also cooking only with water' - as we say in germany.
But we are very careful with what we use as source and what not - be assured.

Excellent.
It would be great to reference these sources or even better to quote them.
Then the endless discussions will most likely stop.

I bet, they would rise up instead. Talking about FMs is one thing, talking about sources the next. They would be questioned anyway. It would be like opening a can of worms. In the end we would have to deliver proving stuff for all we change - order to stop discussions - as long as the change doesn't please anyone.

However, thats not up to me, as I do not own the references about FMs (I'm a cockpitmaker guy).

References 1
References 2
References 3
References 4
References 5

Going through just 100000 pages of the above sources should give anyone a fairly accurate impression of the Fw 190. While the discussions would hardly stop, they at least become interesting and useful.

you not right...

m-82a have 5-7 min "forsazh" (in fact, sometimes, pilots used forsazh 10 and more min if this was need and sometimes kill engine, of course)...

forsazh for m-82a = nominal power m-82f, so la-5f's have good perfomance with 550-560 km/h at SL for good plane and without any really hard time limits (in tests F have some problems with cooling cylinders, but if you see "problems", this not mean problems not solved)...

m-82fn can work on forsazh 10-15 min - this have in ALL la-5fn and la-7 manuals and you can see this here - "Взлетный режим - не более 10 мин" and "Температура головок цилиндров - 250° (не более 15 мин)"...


EDIT

after all i read FN-manual again, some things remembered, do some little research and what can say now - m-82fn, like m-82f, can work on forsazh all time of flight if aircraft have good cooling of engine (like with full or just open all "radiators" or in winter)... all veterans talk about this too...

10 min max for critical oil T and 15 min max for critical cylinders T from manual, with or without some cooling, this is limits for one use without serious after-effects...

and phrase "Взлетный режим - не более 10 мин" - maybe this is what i write about temperatures, maybe it's + and next thing - resource of m-82fn was 100 hours (or something like this), and engine only 6 hours from 100 can work on forsazh... of course, can more, but in this case engine need to be repaired or he not work good all 100 hours... so, this is cautions for long life of engine and cautions for one sort of pilots ("культура эксплуатации двигателя")...

so, something like this... maybe i somewhere little wrong, maybe no (i think no), sorry for mistake if what...

In response to several posts concerning the new drag profile of the FW190 and the suggestion that a test be carried out, I have produced the following results of deceleration rates and ROD's in the landing config. versus the Bf109

They are in no way scientific, but do show that there may be an issue with the current coefficient of drag setting applying to the whole flight envelope including rates of descent in the landing config.

I do believe that the current settings provide a good dogfighting FM and in no way would it be necessary to change that. However, some tweaking of the drag coefficient to produce more drag in the landing config. may add to realism as currently it does seem to be a little in error.

Here are the results of the suggested tests:-

Please note error in ROD:- Should be "mpm" (metres per minute) not "mps" (metres per second)

Thanks for going the length to do the testing and preparing the results in an attractive way.

It appears that compared to real life procedures for the 109, the 109 is totally off the mark, the 190 being more reasonable. We get a glide ratio of ~1/3 for the 109 and ~1/5 for the 190.
