What would raise international standards?
From the comments posted in this thread it seems generally accepted that some international airlines have dramatically lower standards than US airlines regarding pilot proficiency in what used to be considered basic flying skills.
I doubt that the American flying public is aware of this.
I'm wondering what suggestions others have for ways that situation might be improved, as it doesn't look like something that will go away on its own.
Present case aside, let's say that a number of pilots currently flying into the USA are not actually prepared to land without benefit of an ILS.
What might get done about that?
Can the US unilaterally prohibit any international commercial pilot who hasn't demonstrated proficiency in landing without an ILS in the last X days from attempting such a landing in the USA if carrying passengers?
Or, if trade laws and international politics make that kind of move impractical, could there be a voluntary standard of testing airline pilots that is uniform around the globe that airline companies can put some or all of their pilots through, as they choose, but the percentage of pilots tested and their scores is made public and visible to passengers selecting which airline to book with?
