IO 540
You make some good points, however, if you refer back to my original post, I was recommending being in the IFR system under light IMC or VMC conditions where the CB's are visible, in order to secure sensible deviations without worrying about airspace infringements etc.
As you suggest if embedded then get on top if possible, but with the limitations that you earlier referred to i.e. possibility of running in to one on the way down.
I flew for four years in Singapore, initially was happy with on-board radar, after a few scares put in stormscope to help with identifying attenuation issues, eventually fitted water diviners and prayer mat too, just to be sure
