Canute
I go back to this from HP,
On the military hardware I flew (Global Express) if visual with traffic that we could see would shortly cause an RA, we would invariably go 'TA only'. We invariably did the same in our instrument pattern when you knew ATC-coordinated traffic was likely to result in an RA which would just spoil everyone's day.
This cannot be SOP for all operation of the Global Express by UKMil.
