And where is the instruction from ATC to the CRJ (now flying a VFR circling approach to 33) to look out for the helicopter?
Seems to me that what had been IFR from VFR separation with the onus on the helicopter to spot the FW visually had now become VFR from VFR separation with no indication to the FW that the helicopter was there.
Might have given them some vital SA.
