Hi KG.

That equations are interesting. But as far I could see, drag is not included into the bombs' FM.

I've tested all sort of bombs (German, Russian, Japanese and American) in my level bombing tests, with masses ranging from 60 up to 2000 kg; and I didn't see drag effects.

Basically the manual targeting is a BS Elevation Angle calculation using the classical equations for parabolic motion, and utimately that depends of the falling time. If there would be a different drag effect for every bomb's weight and shape (like it is IRL), such BS Elevation Angle should be dependent of the bomb type, and therefore it would be different for each one. But it is not the case.
And, of course, I used the classical equations for parabolic motion you've posted several posts above.

What I observed is the wind effect over the free fall weapons. But all bombs are affected in same way. And this should be sufficient to guess that we've a simple and newtonian FM for all bombs in IL-2, with the crosswind component (when it exists) as the only force vectorially combined with vertical and horizontal velocities acting on a bomb, and determining its path.
