We've done hoist cycles in the tens of thousands for the Dutch pilot service over the past 15 years and never had a problem with the Breeze cable cutting system. We wouldn't think of making the request but I am quite sure the authorities would not allow disabling it. On the other hand carrying a manual cable cutter seems an overkill, because if it gets that urgent the hoist operator probably would not be quick enough. We have had our cable or static line tangled on deck at times, but a little patience works wonders... Having the luxury of OEI hover capability also gives some peace of mind!
