I used to get induction icing regularly in the Islander, flying in winter around Shetland & down to Scotland. These were carburetted but it wouldn't have mattered a jot because it was snow & ice blocking the airfilter in the intake. Mind you, conventional carby ice was common too, but I'm tryign to address induction icing. I've never seen a design more prone to blockage than the BN2. Not even a drain hole (until one was added by the company
) to let meltwater out of the housing. It's not fun at 0200 in gales digging my fingers around the filter to remove impacted snow so I could depart again.
