Indeed, I am now also convinced that this is the solution and that it would be a good thing.
Have to disagree with this.
What we need is the current recommended practices to be correctly trained on a world wide basis. Collectively, the industry can't be bothered to go to the (very modest) expense of doing so. As a result we have 'one size fits all' dogma about how TCAS should be used, rather than a proper understanding of its strengths and weaknesses, in a significant proportion of the industry. So we have dumb incidents happening, which people think can be solved by yet more automation.
The existing equipment and training recommendations are fit for purpose. We just need to use them.
