My question was indeed intended for the enroute IMC part for the hobby GA pilot who simply wants to climb to the nice weather when going somewhere (assuming cloud base at destination is high enough for regular VFR approach).
I do like the ability to get a limited IR (EIR) without needing to commit to all other aspects involved with a full IR and was simply wondering what the aircraft requirements were.
When I'm home I'll go search with the above tips on where to search, thanks
