Rainboe - I think you have missed the point! Note the words
IF you have satisfied 'our' approach '2.5%' requirements i.e. you are BELOW the F15 limiting mass, you
will have the required climb performance, and if the decision is made to g/a straightway then that is the procedure to follow. Let's for example, consider an engine failure just above 50' on a CAT III approach and still in cloud. It is a brave man who accelerates to Vref+20 during the g/a, I propose - I don't think I would. The section you quote in the OM is, as I said, for the g/a FOLLOWING a 'continue' decision. In my book, the scenario I have added (for the sake of completeness) is the same as
"In the event of engine failure during a two-engine go-around,
ensure that the two-engine go-around procedure is actioned and
climb at Vref +5 to Aa. Limit bank angle to 15deg. Subsequent procedure will be the same as for engine failure on a Flap 15 take off."
Anyway - back to CIA.......................
