Hi MAPSHIFT
As an ex Bluestar, I'm sure you'll also be aware of the cockups made by our guys in the slavish pursuit of the monitored approach.
The Cat 11s flown in Cavok to allow for a late landing clearance down to 100Radio, or conversely the go rounds flown from from Cat 1 DA before a late landing clearance had been given, much to the despair of ATC!
The complete lack of a coherent SOP for a monitored circling or visual approach also didn't help because a handover at MDA was mandated! What MDA would you use on a visual?? I could go on, but life's too short!
