Best of luck with the test my friend.
Thanks. In the end I just did what I thought pertinent to do and had done during training. I ran through the checks on the ground without calling them out, in the air I reverted to my habit of saying them aloud from memory...it seemed weird doing them silently.
Icing I commented on the OAT a few times, 'thought aloud' about using the deicing equipment a few times and very obviously looked at both wings regularly during the flight. I think the examiner got the point that I was thinking about it.
I didn't really like the idea of 'pretending' to be in icing conditions during the flight and I judged with the specific examiner I had that if I constantly made references to ice that was obviously not going to materialise he would think that I was being superfluous. He didn't comment on it during the debrief so I can only assume that was OK.
