Sorry, but the CBU 105s also work with GPS and ins... in particular the 105s have the WCMD... Wind trim corrector. It is also present in the bomb configuration on the MFD. A wind correction is already set on DCS. I'll leave you a wiki page. https://en.wikipedia.org/wiki/Wind_Corrected_Munitions_Dispenser
That said, maybe the 105s aren't the best weapons for this mission? If the wind actually affects its performance too much, isn't it better to use other weapons?.
N.B. It's not a polemical post, but it's just to have maximum realism. Also in the Mission Briefing... "Popeye had a weather briefing prepared for us. During the evening the winds have begun to pickup, which has had the benefit of helping clear the majority of the clouds out"
ok...i find the solution... The problem is the bombs attached to the paracute after the cluster was opened. Setting a BA 1000, the wind is too strong and moves the charges. I set the BA to 400...target hit.
TCKnight's post in Red talon part 2 Problem CBU105 and wind... was marked as the answer
