Quite right. It's something that seems to get forgotten when any discussion about civil use of NVG comes up, particularly with CASA. It's not easy and does require training but I don't think anyone is advocating the use of NVG in the same way as the military does. It should be used as a safety aid not a tactical aid. It used to be regarded as dangerous to go flying in the dark, or low flying, or in clouds and if you go back far enough it used to regarded as dangerous to go flying! We have developed training to learn how to cope with all of these situations and the regulators rules to ensure safe operations. The same can be done for this and the longer the regulators leave their heads in the sand the longer it will take to make any progress. I've obviously got it wrong but I always thought that they were there to help the industry progress not hinder it!!
