Re rpt jets, maybe you're right, because they aren't only mixing it with other ifr pilots but people like me in a tecnam.
However that is consistent separate from this incident involving two small ifr aircraft.
Again are you saying that given a similar situation, two ifr pilots don't have the knowledge to self separate ?
The more cta you put in, the less airspace I can use etc. That then creates what Dick calls roadblocks in the sky. Which then forces other aircraft into unsafe situations.
