Just noticed this thread. I have been using the Standard OHJ for more years than I care to remember, basically because that is what I was taught and it was the subject of CAA procedures etc. I am now a trifle worried that there are alternative views and even alternative methods being implemented to save time, fuel etc. Like some of the last posters have stated, if we just use the Standards already in place, even if they are old, then we all know where we are meant to be.
