Hello All,
Having fun with Phase 3, flying a campaign with the Bristol Scout in May 1915
I have noticed, though, having also flown the Alb.D.III and Alb.D.V in Quick Combat, that there appears to be a marked change in the altitude effects on the fuel/air mixture balance (a marked change since Phase 2).
Both the Alb. types, with inline stationary engines, were effected at a much lower altitude than before. I noticed a significant effect from 3000-4000 ft in Phase 3, but it was correctly set at about 5,000-6000 ft in Phase 2 (the carburettors of this period were either slightly less than the stoichiometric or were slightly lean for take off at full throttle, which offset the altitude effects to this height).
The Bristol Scout on the other hand, with a rotary engine, appears to be largely unaffected until it gets to 5,000-6,000 ft. But a rotary engine of this period should be effected from as low as 3000-4000 ft, as it starts from a slightly over-rich base-line, set by the pilot, for full power at ground level and fully open throttle. This is, therefore, the complete opposite of what I would expect.
Is there a global setting for altitude effects on the fuel/air mixture that could be tweaked back to Phase 2 levels, or is this something that is set individually for each a/c by the flight model?
Sorry if this sounds like nitpicking - I realise this probably won't bother that many people, as most seem to fly with mixture control set to automatic in the workshop settings, but it bothers me in much the same way that wholly incorrect markings or incorrect a/c modelling details would bother others. This is not an issue about questionable performance (one reference source citing one set of figures, another citing something very different) as I know that many of these a/c did not have the manual mixture control for altitude that is currently necessary in OFF, and the effects of altitude on normally aspirated piston engines without mixture controls is well documented. So, having to use the manual mixture control, or set them to 'automatic', does bother me in a rather aspergic sort of way
Would it be possible for someone on the OFF team to look at this, and then if the OFF team agrees that it is so, correct it for a future patch, perhaps after the more urgent details have been dealt with?
