109 prop pitch (rpm) and the supercharger

[pstyle]

I think Klem had mentioned this last year someplace on the forums.. but I’m reviving the issue after having just finished reading “spitfire on my tail” - http://www.amazon.co.uk/gp/product/1...ls_o05_s00_i00

Ulrich Steinhilper, in his auto-biography (chapter 16) , talks about managing the prop-pitch on the early (E3 and E4 variant) 109s during the Battle of Britain. He states that, in order to achieve max climb rate and airspeed (particularly at higher altitudes) one had to constantly increase and decrease the propeller pitch. Increasing the pitch would engage the supercharger, which would be run for a short period (i.e. a second or less?) to force more air into the cylinders, then the pitch would be dropped back down again to disengage the supercharger and convert the power gained into airspeed, and allowing the engine/ supercharger to rest.

Steinhilper suggests that this prop-management was responsible for the pulsating sound of the German aircraft engines as reported on the ground. The fact that he has conflated the two (rightly or wrongly) suggests to me that this propeller management was continuous, and the changes between the flatter and coarser settings occurred over a few seconds (at most).

Steinhilper indicates that this was one of the most important skills for a 109 pilot to master, so it must have had a significant performance impact.

Is this effect modelled in the game? Does this constant prop management to engage and disengage the supercharger, allowing for best continued speed?

My experience is that the prop control is modelled to move quite slowly in the 109 in the game. But perhaps the range over which this manipulation needs to occur is quite narrow, just either side of the supercharger threshold?
