Which safety assessment was made and validated ( and by who) which allowed visual separation for an helicopter at 200ft to pass below the approach path of an aircrfat at 3 or 400 feet ?, resulting in a 100-200ft separation ?That is the question I would be asking first.How about which actions were taken after the previous incidents , and possibly acting on the normalization of deviance , would be the next
You may bet:
1. These persons, making such SA, won't be part of any investigation especially not part of court trial process.
2. Bad systems do not have independent and respecred SA - that is the first reason- why they are bad for workers, customers and society
3. Last, but no least, it is very hard to prove financial benefits of making independent SA and respect it afterwards.
