Yes my questions relates to Australia, being that it requires 2.5% gradient in the MAP even with one engine. I was thought how to calculate what to add on with the whiz wheel as explained above. But I've forgotten exactly where you get the "height required to achieve missed approach" so once I have the 2.5% under and lined up with the 2.0% on the whiz wheel I can go across and read above this height which will give me the 2.0% value. I then am able to work out the difference in heights between the two and add that figure onto my MDA. But I am not sure which height to use...any one know for sure?
