It was a regular occurrence for a Minimum Departure Interval to be put on the departures to the south,often at short notice. This led to airfield delays often without notice. This trial has meant that the traffic is presented to Daventry sector in a known and expected manner leading to the lack of need for last minute restrictions and therefore a more regular and consistent service to the operators.
