Aviate1138, you ask if I am a pilot. You obviously have not read the Unsafe Skies presentation which this thread was about.
I am not an extremist and I do not believe that:
Radar apparently, solves all aviation safety problems so far encountered.
My presentation clearly explains that if you have radar you may as well use it as an extra safety feature.
May I ask why you are commenting without at least reading the presentation? You will find there is a rational explanation of why we in Australia use a ‘do it yourself’ system aircraft to aircraft when in cloud, under good radar coverage, rather than use a radar separation service – at least to help prevent Controlled Flight Into Terrain accidents.
