Visibility & Airstrikes

[Big Ivan]

CS Folks,

I'm directing this to some of the Air Force Vets out there regarding airstrikes availability as it relates to visibility in the CS system. But if anyone has an opinion chime in, please.

For scenario design purposes in WWII and the CS, is there any general rule of thumb on design regarding airstrike availability as it relates to visibility in the game system?

Obviously when the visibility is clear, overcast or hazy airstrikes should be available to some degree (visibility: 15 or higher). But how about when its Lt Rain/Snow or squals (visibility 8-14)? What about when visibility is Hvy Rain/Snow (visibility 5-8)?

I'm petty much convinced when its foggy or night forget about it (visibility 1-4) in WWII combat simply because the planes were not as advanced as today. Seems to me that in WWII most flying was done by sight and not instruments but if I am wrong correct me.

I'm curious if there would be a percentage drop off as the visibility drops. For example say I had a scenario in hazy visibility and allowed 10 airstrikes. If I would then change that visibility to something less, what would I then have to change/drop the original 10 airstrikes by to make it more realistic given the new visibility?

Thanks
