PT6A thanks again for all your very useful input. However, I am still confused. If the new Jepp DAs for Non-Precision Approaches do NOT include any add on, then surely they should always be factored to prevent descent below this 'hard' altitude? As far as I can see, the new DA is the same as an old MDA. The difference is that the charts now display the approach as a continuous descent procedure with an arrow showing the latest point at which the Go Around should be initiated.
