Thanks guys.
I know that the standard missed approach gradient is 2.5%.
So, does it means:
1.In case of one engine inop, as long as I can still have a climb gradient > 2.5% during missed approach, I can just follow the published missed approach procedure?
2.In case of one engine inop, and I can not have a climb gradient > 2.5% during missed approach, I need to follow the special engine out procedure instead of the missed approach procedure?
3.In case of one engine inop, and I can not have a climb gradient > 2.5% during missed approach, and there is no special engine out procedure, then I either maintain runway heading and climb to MSA and request radar vector, or I follow a SID which is appropriate?
