UK IMC rating holders are limited to 1800m met visibility on takeoff and landing anyway
Oh really, are you sure?


But BA pilots are excluded, right?


1800 m is a nautical mile, so you are telling me that a IR holder in UK can't land at airport with visibility 1/2 mile (CAT I) assuming runway has CAT I? The fact that he/she can't takeoff with visibility 1/2 nm is no less shocking.
