Note

Open-loop instructions are still used by the Controller in time critical situations, for instance: to ensure immediate separation of the aircraft versus conflicting traffic; to avoid adverse weather (for example Cumulonimbus clouds); or to make fine adjustments in the approach phase to maximise the runway throughput.
