That being the case then, if as it turns out the PIC happens to be the one to remain on instruments until the 2IC lands visually, how many PIC's out there are entirely comfortable not looking outside, at least to some extent, to see what's going on whilst the 2IC is landing the aircraft in poor viz? Or in practice is there a scan of some sort going on here where the PIC is looking outside to monitor the approach, and cross referencing to the instruments?
Surely with the proximity of obstacles at the platform, and the risk of departure from optimal approach profile due to poor seeing conditions (depth perception and illusions), wouldn't it be more prudent for both pilots to be looking outside? As a NFP PIC in these circumstances I'd be very uncomfortable arriving at the platform without actually observing what's going on outside.
