In most Organisations the tuning of the Radar is informally taught during line training, legacy driven, and on this hill of hindsight may well be inadequate.
that is a most telling statement DB - especially given your previous statement
However as an ARA can quite legitimately get you to 200 feet and still be in solid IMC, only the RADAR can keep you safe, or so we have all assumed.
perhaps the attitude to training for the radar has slipped across from oil and gas to SAR.
We come back to replacing a dedicated and fully trained radar operator with a co-pilot - cheaper but clearly far less effective.
As for NVG - everyone who uses them properly knows that the higher you go the less effective they are - lower is better with goggles hence 200' as a common figure.
