Exact quote, "There were occasions, so it was said by one witness, when Air New Zealand aircraft were observed to be flying in and out of cloud although on the basis of their radio transmissions they were flying VMC.
This was from a ground observer at McMurdo, hardly proof of non-VMC compliance. It's possible for cloud to be between the observer and aircraft giving the impression the aircaft entered cloud.
Thanks for that photo Compresser Stall. Clears things up a lot. It's easy to see how a relatively high overcast could obscure Ross/Erebus completely.
Is it fair to say then you would not descend (today) without a radar or navaid fix?
If you would, can you describe the limits of visual identification that you would consider acceptable in terms of visibility, sight of ground or water or ice and landmarks for descending below MSA under
IFR?
