This is not rocket science and the XCOM radio could do this 18 years ago... this eliminates pilot error from 95% of the circumstances of being in an area on the wrong frequency.
Although this is undoubtedly possible, in practice it would result in missed calls, “lost” aircraft and calls made on the wrong frequency. A system that advised the pilot of a new frequency would be better. But in any case, that’s what pre-flight planning is for.
Here in U.K., my typical “daily” flight is only about an hour and twenty minutes but includes transit through the airspace of four major airports and three minor airfields, including the destination. I’ve just added up how many frequencies are needed. It’s fourteen (sometimes a couple more) and therefore the radios need very careful and timely management. Automatic and wrongly timed radio frequency changes would cause total chaos.
