Back to the airprox board, my main point is that their conclusions and suggestions are at best, impractical. Also I would expect them to be an advocate for increased safety, not appear to state which pilot did or did not take avoiding action, with the implication that one or more wasn't maintaining a good lookout.
A solution isn't to insist on electronic awareness unless it's a common system, available to all pilots., or to rely on ATC in Class G. Re. biz jets or any other CAT, if a pilot deliberately left controlled airspace to reduce airtime,(and please the boss), it would be interesting to see the legal/insurance ramifications after a midair. Yes I know Class G can be flown by all and a few airports have visual/instrument apps. outside controlled airspace but I would imagine most AOC ops manuals would require CAS where possible.
