The problem is that the suggestions were all aimed at the pilots. The myth of crashes caused by single individuals, usually the pilot, persists. Accidents in aviation is a system problem.
Accidents occur because the system is faulty.
Accidents will continue as long as people treat this as something that can be cured by concentration on the pilots. Datalink is digital transmission of ATC information to be received somewhere in the cockpit on a CRT display. This replaces some of the voice communication on the now overcrowded channels. In principle it has merits, but it is yet another complex piece of equipment, yet another change in procedures, yet another bandaid and ill-considered addition to cockpit clutter. Basically, one cannot fix a system problem by adding local patches.
