I am sure there are some generalisations in this method and I am certainly no mathematician, but its a start. Again I stress its only point source data.

This was the method I used.

Ps = Rate of Climb in units per sec.
g= Acceleration due to gravity (32.2fps or 9.8msec)
V= TAS in fps or mps

1g Accel = (Ps x g )/V

So take an aeroplane with an instantaneous Climb rate of say 20msec at 300Kmh (83.1mps)

1gAccel = (20 x 9.8 ) / 83.1
1gAccel =2.358msec or 8.5Kmh/sec (again its point source data)

sorry to bother you

Did you test the 190A-4 and hold the results up against manifatures data?? ( i know the data normaly are in the "happy" end, but it gives an idea if its worth digging more into this subject

The problem with the Antons in game is the function of the komandogerate/prop pitch at low speeds. At low speed the FW190's cant maintain the rpm.
This leads me to belive the prop pitch is too corse, just like trying to climb a hill in high gear, or having no first and second gears in the gear box and the lower gear being third. You can actually try that. Go out and try to drive the car using only from third gear up. You can feel the engine strugling.

That's exactly how our Antons behave.

The auto prop feature of the game has always been off for the Anton Series... Any season FW driver in IL2 uses manual for this very reason. In fact once used it starts to behave a bit more like the Fighter version. You can get more climb more speed and acceleration. Not by huge amounts but it's noticeable

[Jaws2002]

Yeah. The first thing you do when starting a mission in Anton is to sitch the prop to manual. I used to do that before starting the engine.

Wasn't there an acceleration test in the ubi forum once? As far as I remember, the problem lied in the acceleration at low speeds.
Very understandable when you take off. I always thought that Oleg programmed an automatic parking break for the 190

As it has been said: The problem might very well be the Kommandogerät which can't handle the prop pitch at low speeds.
