Is this misunderstood PC at work, applying the changes to all foreign airlines? I am sure there are plenty of foreign airlines that have no issues at all with those visual approaches.
Some maybe more sensible ways to still be PC:
- apply the restrictions per airline bases on statistics of past landings
- apply the restrictions on all flights from east Asia (including US carriers) based on the notion that it must be early morning for the pilots' body clocks (whereas it would be around midnight for flights coming in from Europe)
