Climb gradient on go-around

[FLT86]

Hi All,

I am writing to you regarding net/gross climb gradient.

On books, I've read that the climb gradient on go-around for a turbo-propeller aircraft is 2.5%. Is it net or gross ?

At the same time, still on books, I've read the following for a turbo-prop:

G/A => One engine inop => Approach configuration => 2.1 % gross
G/A => All engine => Landing configuration => 3.2% gross

Should I take into account the 2.5% for a G/A or those mentioned before ?

Same for the penalty of climb gradient on cruise with one engine inop (turbo-prop) => 1.1%.
Should I know it ?

Thanks for your help.
