Ermm.. has anyone got solid data on flak proximity fuzes? I DO know that the early ones weren't terribly reliable, and that well into teh secon world war many gunners didnt even use proximity fuses, they used time fuses, effectively set to go off at a particular altitude. (Hmnn... wonder if they had fuses that worked on atmospheric pressure...?).
Again, bearing in mind that I don't know for sure what the RL situation was, just suppose...
Flak gunners use timed fuses. Guns with particularly advanced sights have an optical system that brings things at the set range into sharp focus but blurs them at other distances. Gunner has to gauge range, one way or another, then set fuse, then blaze away. If the range is misjudged, then only a direct hit will hurt the plane, as the shell wil either burst short or long. Also, in a long engagement, the gunner would have to keep adjusting the fuze settings appropriately - easier to do with high alt targets whose range is changing only slowly than with low alt ones approaching or departing rapidly. The thing about this is that it makes good flak gunning a bit more of a skill. In skilled hands, its stil likely to be pretty nasty low down, but in unskilled hands, low-level planes would be a bit better off.
(further to the above idea, maybe allow gunners to pre-set their loadouts to various ranges, maybe give them a choice of 3 or 4, so then all they have to do is to press a numbered button to swap fro rounds of one setting to rounds of another. And if they run out of ones set the way they need, they can spend a few seconds resetting ones set in a way that won't be useful to them in current circumstances).
Also a possibility is proximity fuzes that dont work until they've been out of the barrel for a preset length of time. A look into the effective blast radius of various flak shells wouldnt go amiss, either.
