I agree that meeting traffic in IMC in Class G in the UK is unlikely, but the risk is there, and no doubt it'd prove to be terminal.
Out of interest how many of you use a mode C transponder while flying in IMC / IFR? (I do) I'm curious as I'm wondering on the usefullness of these portable "TCAS" units (
www.avshop.com). Although they don't tell direction they will tell you differential altitude and range, which are the important things and I'd be happier flying IMC in the UK without a RIS if I had some means of traffic avoidance.
