that is a most telling statement DB - especially given your previous statement 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.
The co-pilot will help you out of a disorientation though
