LB is correct. A competent organisation involved in risk mitigation (which is all Airservices does) would have the numbers. However it seems Airservices mission is to maximise cash extraction from industry by charging the highest price for the minimum of service, like all parasites.
Their mission statement:”Please God! Not on my watch!”. They pray that they can take their bonuses and retire before the consequences of their cost cutting appear.
In Airservices that ensures nothing will change until there is the inevitable 200+ killed in a jet mid air.
The tools are there, the data is there but the Governments expectation of its annual dividend precludes rational thought.
To put that another way, if a bunch of amateurs can see the accident developing on Flightradar24, why can’t Airservices? Where is the ADSB we paid so much for?
