Howdy. I noticed and started reading this thread about a month ago. Then got extremely busy at work on some end of fiscal year projects that need to get out and just haven't had time to post anything. I don't want to butt in on your research so I won't say too much...you may be like me and love the challenge of figuring stuff out.
But I will say this....true altitude and indicated altitude are basically the same thing. The difference being true altitude would be what a tape measure placed between sea level and your plane would say and indicated altitude would be what your instruments tell you. With modern laser and radar equipment, the difference between the two could be mere inches. In addition to indicated altitude, there are 2 other altitudes you need to bomb accurately. Here's a list of the different altitudes....

Also, you don't need adaptive bombing. There are definite formulas that are used, but some planes use slightly different values. Also, the IAS/TAS chart that's in the game is only giving you the partial equation...so the values for TAS are usually WAY off. That chart shows the aircraft's speed increasing linearly (on a straight line), but it actually increases on a curve. Fortunately, you don't need a differential equation to calculate it...a simple polynomial is all that's needed. In other words, basic mathematics. LOL
And yes, OAT (Outside Air Temperature) is very important for calculating that curve. With OAT in mind, I recently noticed that the Free Air Temperature gauges on the G4M1-11 Betty are bugged. I've reported it to DT so hopefully it will get fixed. Having air temperature gauges that work properly come in quite handy.
Anyway, I've said enough...but if you guys would like some help, just let me know.
