Script that allows an attached prim to become visible only when jumping and/or flying, is there one?

I assume that you have had a timer polling llGetAgentInfo to see whether AGENT_FLYING is TRUE.  Try polling for AGENT_IN_AIR instead.  That will be TRUE whether you are flying, jumping, hovering, or falling -- as long as you are in the air.

The other way to do it, which might be better if you want to show the wings only when the agent is flying or jumping (but not, for example, when falling) is checking llGetAnimation.
