Thanks for the response guys,
Aviophage, I think right way up has answered your question posted towards me about why would I use an autoland in an emergency situation.
As the part of the world where I operate, we do have some pretty bad sand storms in summer, and those early morning fog in the winter.
DeltaGolf, and again everybody else thanks for your efforts much appreciated. I have already passed on my question to the airbus technical representitive and he says he would get back to me.
Once I get his response, I would gladly share this with you guys asap.
