He doesn't want you to know what the coverage is at 6000ft. The maths are an "anal pluck"
Quote: "Re the first, the cover of interest to "us" is the 10,000'."
Who is this Royal "us"? Do we assume this is your canvassed majority of Day VFR owner pilot flights in Australia? Or just another sales speil? I guess this includes the 8,000 odd RA-Aus people who can't fly that high anyway.
The illustration, except for existing radar, shows nothing to do with flying below 10,000ft and as for CFIT, how many airports are at or above 10,000ft in Australia?
From memory, and I'm sure someone will argue this point, all aircraft must descend at some point in time to ground level which unfortunately leaves Oodnadatta out in the cold for this ADSB.
