Night Watchman regarding airwave that is an interesting development.
Crab I have it on good authority that the 92 does not have HF fitted which I agree is very strange when the CG has operational control of the CG helo's when on task it has been known for the Northern stations to use HF to maintain contact with them due to the distances involved and the dog leg that is sometimes generated between the Helo, ARCC and MRCC.
The AIS transponders will be an interesting development also. As you know it will enable the MRCC's to see where the helo's are in real time, eventually as you say the Mil SAR fleet should have them and the ARCC or JRCC will eventually have the softyware to track them also.
Cyclic, yes Bond fly for other companies but the JIGSAW aircraft were heavily financed by BP as were the RSV's and the ARRC's so are contracted to fly for them only. They have carried out SAR missions to other platforms owned by other companies on a large number of occasions when tasked by the ARCC/MRCC or Jigco but are still tied to BP.
