static; basically yes. Until recently in windy conditions traffic flow through SPL was controlled by regulating inbound atc slots, this by its nature regulated departures as well.
Now we seem to get massive slot delays departing in addition. It would seem from speaking to Swannick that SPL has been given an unprecedented degree of autonomy over the atc slots affecting their airfield.
Lastly SPL appear to be able to impose flight suspensions on the basis of wind condition, normally this procedure is triggered by low vis or radar failure.
