Griffo. With up to six aircraft being given as traffic sounds to me as if a lot of time in the cockpit would be heads down attempting to write down all of those call signs and to try and work out which is relevant traffic.
If it’s heads down it’s clearly less looking out!
Lead. Yair. Triple mandatory mandatory mandatory 60 mile diameter 10,000’ CTAF s is the way to go.
Won’t cost the Regionals a cent and make en route flying below 10,000 such a nightmare that hopefully private pilots will sell their aircraft and travel in a proper airline aircraft.
Hold on. That’s already happening!
