You missed the point, Teresa Green. Your words were
into a unknown airport
My point is it shouldn't have been so because the regs require pilots to be familiar with the route, sometimes even physically route endorsed, for RPT ops. And that would include being
familiar with all the likely alternate airports even if they hadn't actually been there. I do stand by my statement if the operator is using the sim properly then the crews should at least have had exposure that way. If it was "unknown" then something is wrong - which was my point.
Incidentally, why would the window be "possibly unstable"? Boeing windows don't do that without heat, you are just required to slow down at lower levels. I would have expected Airbus windows were the same. Maybe a 'Bus driver can clarify?
