But it makes airborne tasking of an asset somewhat difficult when the tasking agency only uses HF. The MCA knew this and still procured aircraft without it.
Good to see Bristows taking the initiative on NVD, I'm sure the Stornoway and Sumburgh crews will be very glad of it.
No vote Joe - you are right about needing to look downwind with a radar search - this can be achieved flying into wind or crosswind if you aren't limited to a 120 radar.
