Interesting question KPax. No doubt the Mk 6 will bring additional capabilities in poor vis ops but some of the real show stoppers (poor icing clearance, low millilux operations) won't be addressed by the introduction of this new model. Interestingly there are some impressive developments that are available for helicopters (and Chinook in particular) that MOD have chosen not to buy. Goodness knows how MOD intends to employ 60 airframes. The total costed flying hours for the fleet in the future are unlikely to be as high as on current ops ....send for the mothballs!
