What major airports are most affected by adverse weather conditions? Any ideas which airports are more times closed during the year because of meteorological conditions, such as heavy snow or fogs?
Applying technology and procedures could provide instrument approaches under a wider range of meteorological conditions. So why some airports still have to be closed? Examples: last month GVA had to be closed for a whole day, and GRU during the winter suffers from intense fogs causing flights to be diverted to CPQ and/or GIG.
