MiG-3 Manual mixture control

[TAIPAN_]

So it's pretty clear that 50% is auto, 100% is boost, and to manually control mixture its between 0-50% (from the Dev notes).

 

My question is what happens between 50%-99% mixture if we use it? It seems to affect manifold pressure so does that mean it's a "partial boost"? Or is it something like an "extra rich" mixture?

 

I see some virtual pilots take off in 60% mixture but I'm not sure if that's because it's rich or because they want to use some free boost without hitting the time limit.. 

 

Also if people DO use 60%-70% mixture for a partial boost is this gaming the game exploiting an implementation limitation in this unique mixture-boost? or is it a realistic strategy that's used in the real airplane?

Boosted Mode starts aroun 84%. It appears that there is a range for automatic from 50% - 84%, with higher in the range being slightly richer than lower. But I am not sure if this is realistic or not.

Thanks. Possible that the range is a limitation of how it has to be programmed, wondering how that compares to the real aircraft if it only has 2 fixed positions for 50 & 100, and manual below 50?

No idea, really. I don't fly it as much as I used to, but in combat I would run it at full boost, at 60% or so for cruise, and about 35% if I felt I needed to save fuel. Lower mixture on takeoff seemed to help a little with the excessive torque and tendency to ground loop.

Boost starts at ~86% fuel mixture, but you can push the aircraft into bumps of boost in the 80-85% range if you ram the throttle to full fast.

 

Speaking personally, I tend to cruise at 50%, take-off at 100%, lean at 30%, and when in combat I usually rest at 85% to maintain continuous (at 100% RPM) and then push directly to 100% when I need the extra power.

Thanks, I noticed a bit more power last night using 80%. Mixture between 50-70% doesn't seem to make any difference though.

 

Any idea what the time limit is to run at 85%, which seems to be about 1% of the boost range? or 90%?

100% is 10 minutes on paper, but reportedly 15 minutes in practice. I wonder is lower boost ranges can be unlimited or close to it...
