The reason I asked is that the ARCCK use 190nm as a standard for all S61s but it appears that different operators have different ideas about this - where one will stretch it to 210nm, another won't go past 150nm - is this the elephant that Geoffers refers to?
The RAF cabs all have a quoted 240nm providing you get rid of enough role equipment to allow max fuel at 21,400 lbs aum but we all have the same aircraft fit, the same MLA and the same planning SOPs. When the ARCCK asked the various operators about RoA they didn't ask all the different S61 operators which is why I am asking the question.
NRDK - thanks for the offer, it might come to that since the SAR(H) manpower plot for the military looks ludicrous and unlikely to be self sustaining.
