I like your reasoned posts and fail to see why Seldom seldom sees the point you are making. I always, what ever kit I had on board did a DR calculation and pressed the stopwatch on the dashboard. When my DR time was up, and it had a safety margin put in by me, I reacted. Coming into Norweigan fiords from the sea at night and in poor vis needed this bit of very basic airmanship that I was taught as a safety net very early on in my career. I do hope that modern day pilots are not so engrossed in amazing kit that they forget the basics. It can kill you. DB
