"Your local MRSC is only your tasking authority when the incident is within 30nm - outside of that it is ARCCK. As such, your flight should have access to the RCS and a direct line to Kinloss - if it doesn't then someone has been telling porkies about command and control of SAR helicopters."
Sorry Crab but that's wrong. For an incident requiring an MCA helo over 30nm ARCC are contacted and if confirmed that the helo is 'closest' then the tasking and scrambling reverts back to the MRCC (no MRSC's nowadays!), hence no direct line between ARCC and SAR Flight because it is all done via us here at the parent MRCC. The SAR Flight keeps us updated with their status hence no need for RCS, but I believe it is on the way.
So take it from somone who does know something about command and control of SAR Helicopters.
