High level bombing questions

[Woke Up Dead]

Two questions about high level bombing.

Does anyone have a IAS/TAS conversion chart for the cold maps in IL2, like Moscow? Bombsight Table 2 and all the charts I can find seem to be calibrated for average spring/fall temperatures, but the Moscow map is much colder, which affects TAS calculations, which in turn affects bombing accuracy.

For example, on the Crimea map, at 3950m and an IAS of 270km/h the TAS is 340km/h, according to the wonder-woman view. But on the Moscow winter map, IAS of 270km/h at 3950m is 312km/h.

If someone had a chart, or at least a basic guideline for calculating TAS on winter maps, that'd be great.


My second question pertains to the Soviet bombsight on the Pe-2, Pe-8, and IL-4 (now also found on the single-engined Japanese bombers). I find it to be very precise but not accurate; it consistently drops bombs with the same error, depending on bomb type and plane type.

BFS Thor made a great level bombing manual with a chart to correct the Bombsight Table 2 program, but it does not include the IL-4 or the Pe-8, and the Pe-2 information is now inaccurate or was never accurate to begin with. Doing my own tests on the Crimea map, I found the following corrections are needed, all at 3950m:

Pe-2, 250kg bomb: go by the sight
Pe-2, 500kg bomb: go by Bombsight Table 2
IL-4, 250kg bomb: go by Bombsight Table 2 + 0.4 degrees
IL-4, 500kg bomb: go by the sight
Pe-8, 500kg bomb: go by Bombsight Table 2 + 2.0 degrees
Pe-8, 1000kg bomb: go by Bombsight Table 2

Does someone have a more complete chart, and is it possible to fix these inaccurate bombsigts in future patches?

Thanks,
