It appears that where there have been 'issues' with flying operations (including AEF) the resultant 'fix' has been to instigate more equipment fitment, and compulsory ATC requirement.
Again this has ignored the basic VFR rules that one must adopt a good look out rather than rely on equipment that means even more instruments to scan (inside the cockpit). The whole ATC radio thing also gives a false sense of security in the VFR regime of operations and ignores the basic VFR concept.
