I would say that the 50nm standard gets used all the time Akro, daily and hourly.
So my question - and it was a genuine question - is whether the separation requirements for non ADSB aircraft (ie the 100nm you tabled) is more arduous now than before the Dec 12 ADSB requirement. If the answer is yeas, then Dick and others are being penalised because they are unable to comply with the regulation requirement due only to lack of equipment.
If the answer is no, then I struggle to see why he couldn't do the same flight on Dec 11 as Dec 12.
The other thing I don't understand is how overseas aircraft are treated. I presume all the bizjets with N tail numbers in hangars around Essendon do not have ADS-B and I also assume that International carriers do not have the Aussie ES ADS-B units. How are these handled and is it any different to how Dick is being directed to operate.
