I doubt that the RAF sea kings have that sort of auto-hover kit as its mainly useful over water (where there is nothing to hit when hovering imc
). Maybe the navy does?
The new Jigsaw AS332L2 has Eurocopter's own kit which is superb and so far seems much better than the LN450 fitted to the S61s . The only other aircraft I know of that has that kit is a Hong Kong-based SAR outfit.
