So Dick, what approach would you expect from an ATC who could use the ADS-B?
That is exactly the point - ADSB has nothing at all to do with what you see in the cockpit (unless you're the lucky one getting ADSB-IN traffic cluttering up your screen).
Was Dick really expecting to be given 500' descents all the way to the ground, by his own personal controller?
Sounds like a slightly confused attempt to revive his upset at the cost of adding equipment to his private jet
