I've been doing a decent amount of F-5 bombing lately, and I just want to confirm what I think I'm seeing.
For level delivery of Mk82SEs, I'm seeing a decent amount of variation in reticle depression needed. I stick to 500 AGL/500 IAS delivery profile, and find that at sea level I need around 140 mils of depression.
Recently I hit a target at 11,500 ASL, and 140 mils caused the bombs to go way long. A second strike with 100 mils depression was centered on target.
It would make sense that atmospheric pressure would change sight setting requirements, and I assume that's what's happening, but I've never seen it mentioned in any manual or tutorial. I assume there's a way to account for this other than trial and error?
