The CAA have stated that they consider ADSB is the way ahead. If Sky Echo behaves in this test as promised it must be the answer at £600.
I am situated 12 miles from Dundee with hills over 1000ft in between. I can see aircraft with ADSB on the ground here and at Dundee Airport. The Leuchars Grobs use Flarm and currently mode S as well. Some mode S returns (MLAT) I can see from about 1500ft upwards which is at least as good if not better than radar in the area. This is being achieved with one less receiver than is ideal. I genuinely believe we are close to the "VHS or Betamax" decision time.
tescoapp, I don't think there are any parallels here with the Beechcraft accident. The AAIB report left more questions than answers!!!!
There is no need for anyone here to feel inadequete.
Very few of the scheduled aircraft that fly to Dundee have ADSB.
