English proficiency for pilots, I've learned during this past year is a real issue in Afghanistan. On a daily bases we deal with pilots who lack any real understanding of english that cause a lot of problems when you are trying to merge traffic for sequencing, let alone with trying to direct them to a specific parking location.
I know that there are several companies that teach and test aviation english proficiency (I wouldn't mind working for one of them), but how can we enforce a certain level of english proficiency for pilots that want to fly to/through other countries?
