Bluenose - Branahuie's quote -
Under an agreement between the MCA and the MoD, tasking of these assets is normally undertaken through ARCC, RAF Kinloss. Exceptionally, when helicopter assistance is necessary for immediate lifesaving, the MCA can task the helicopters direct and then notify the ARCC as soon as possible afterwards.
- means that since the SARF Cdr controls the ARCCK, he also has opcon of all the SAR assets, including the MCA ones. MRCCs are allowed to independently task their assets for tasks within 50nm.
