All the Dundee and Leuchars based aircraft are equipped with either ADSB, Flarm or mode S and steps are underway to have the Perth based aircraft similarly equipped.
Leuchars and Scottish Tay sector control IFR arrivals and departures and there are letters of agreement between all parties. There is a determination to make this work in what is a busy training and recreational area.
