A good example of correctly tuned radar. The point I was making earlier about interpretation of the radar information is clearly shown, with sea clutter appearing behind the target in-front of you. If the oil rig was instead a 500' cliff there would be a very deep arc absent of sea clutter behind the target, which should flag a big warning in the pilot SA loop.
The radar on the accident aircraft, if correctly operated and interpreted, should have provided a warning sign of what was ahead even if the active waypoint marker sat directly on top of the Blackrock radar return. If they send an S92 out to re-fly the accident mission profile I'd like to see what the radar image looks like.
