Thanks for all these informations.
I had a feeling that those visibility and ceilings values would somehow have been based on aspect of the local terrain.
Thanks for clearing that out.
The part that is still bothering me is :
We had strict rules on landing weights and tailwinds so would not have landed. Over 5 knots on a dry runway of tailwind prohibited us from landing.
I presume that all operators there would have the same criteria.
Do they ?
