In my simple world there are 2 big differences between artillery and aircraft which make it not worth worrying about Coriolis effect in the latter.
Firstly once a shell is fired that's where it's heading so all the calculations beforehand have to take everything into account, whereas an aircraft can be constantly corrected until the destination.
Secondly, a shell is relatively small, dense and fast compared to most aircraft and so the effect of wind, etc will be relatively less and other effects relatively greater. In an aircraft wouldn't the wind effect make any Coriolis effect negligible ?
Cue someone to tell me I'm talking rubbish
