Veloo,
could u check with the Italians if they can produce some software which will auto sequence a/c to form a long line( with 5 nm spacing inbetween) to the runway in use?
Once any a/c enter KUL airspace, this system must be able to calculate speed and heading for that particular a/c to fly.
Since DCA is paying for the upgrade, might as well ask for a better system which will indirectly reduce controllers' workload.
