Aluminium shuffler. Your post:
4468, your post indicates that you have never flown into an airport with severe windshear, as can happen frequently.
Indicates you have not read my post.
I referred to all
environmental conditions.
AFAIK, no a/c are 'certified' for landing in 'severe windshear'! (Are you aware of the definition of severe?) If that is what you are alleging occurred, then I would counsel you to tread very careful indeed. The added complication you would of course need to address is that the gear seems to have been retracted? Not part of any windshear procedure of any aircraft manufacturer!
As for the suggestions that the B777-300 is unfit for operations in DXB in the summer, again I would suggest great caution. Not that I believe it would be allowed/tolerated, but the allegation is a very serious one!
